INSECTICIDAL PROTEIN TOXINS FROM DOLLAR I(PHOTORHABDUS)

Abstract: Proteins from the genus Photorhabdus are toxic to insects upon exposure. Photorhabdus luminescens (formerly Xenorhabdus luminescens) have been found in mammalian clinical samples and as a bacterial symbiont of entomopathogenic nematodes of genus Heterorhabditis. These protein toxins can be applied to, or genetically engineered into, insect larvae food and plants for insect control.

This application is also a contmuation-m-part of provisional U.S. Patent Application Serial Number 60/007,255 filed November 6, 1995. Field of the Invention The present invention relates to toxins isolated from cacteria and the use of said toxins as insecticides Background of the Invention Many insects are widely regarded as pests to homeowners, to picnickers, to gardeners, and to farmers and others whose investments in agricultural products are often destroyed or diminished as a result of insect damage to field crops. Particularly areas where the growing season is short, significant insect damage can mean the loss of all profits to growers and a dramatic decrease crop yield Scarce supply of particular agricultural products invariably results m higher costs to food processors and, then, to the ultimate consumers of food plants and products derived from those plants. Preventing insect damage to crops and flowers and eliminating the nuisance of insect pests have typically relied on strong organic pesticides and insecticides with broad toxicities These synthetic products have come under attack by the general population as being too harsh on the environment and on those exposed to such agents. Similarly in non-agricultural settings, homeowners would be satisfied to have insects avoid their homes or outdoor meals without needing to kill the insects. The extensive use of chemical insecticides has raised environmental and health concerns for farmers, companies that -1- SUBSTTTUTE SHEET (RULE 26) produce the insecticides, government agencies, public interest groups, and the public in general. The development of less intrusive pest management strategies has been spurred along both by societal concern for the environment and by the development of biological tools which exploit mechanisms of insect management. Biological control agents present a promising alternative to chemical insecticides. Organisms at every evolutionary development level have devised means to enhance their own success and survival The use of biological molecules as tools of defense and aggression is known throughout the animal and plant kingdoms In addition, the relatively new tools of the genetic engineer allow modifications to biological insecticides to accomplish particular solutions to particular problems. One such agent, Bacillus thuπngiensis (Bt) , is an effective msecticidal agent, and is widely commercially used as such In fact, the msecticidal agent of the Bt bacterium is a protein which has such limited toxicity, it can be used on human food crops on the day of harvest. To non-targeted organisms, the St toxin is a digestible non-toxic protein. Another known class of biological insect control agents are certain genera of nematodes known to be vectors of transmission for insect-killing bacterial symbionts. Nematodes containing msecticidal bacteria invade insect larvae. The bacteria then kill the larvae. The nematodes reproduce the larval cadaver The nematode progeny then eat the cadaver from withm. The bacteria- containing nematode progeny thus produced can then invade additional larvae. In the past, msecticidal nematodes m the Stemernema and Heteror ajbditis genera were used as insect control agents. Apparently, each genus of nematode hosts a particular species of bacterium. In nematodes of the Heterorhabdi tis genus, the symbiotic bacterium is Photorhabdus luminescens . Although these nematodes are effective insect control agents, it is presently difficult, expensive, and inefficient to produce, maintain, and distribute nematodes for insect control. It has been known m the art that one may isolate an msecticidal toxin from Photorhabdus luminescens that has activity only when injected into Lepidopteran and Coleopteran insect larvae. This has made it impossible to effectively exploit the msecticidal properties of the nematode or its bacterial symbiont What would be useful would be a more practical, less labor-intensive wide-area delivery method of an msecticidal toxin which would retain its - ? - SUBSTITUTE SHEET (RULE 25) biological properties after delivery. It would be quite desirous to discover toxins with oral activity produced by the genus Photorhabdus . The isolation and use of these toxins are desirous due to efficacious reasons. Until applicants' discoveries, these toxins had not been isolated or characterized. Summary of the Invention The native toxins are protein complexes that are produced and secreted by growing bacteria cells of the genus Photorhabdus, of interest are the proteins produced by the species Photorhabdus luminescens . The protein complexes, with a molecular size of approximately 1,000 kDa, can be separated by SDS-PAGE gel analysis into numerous component proteins. The toxins contain no hemolysin, lipase, type C phospholipase, or nuclease activities. The toxins exhibit significant toxicity upon exposure administration to a number of insects. The present invention provides an easily administered msecticidal protein as well as the expression of toxin in a heterologous system. The present invention also provides a method for delivering msecticidal toxins that are functional active and effective against many orders of insects. Ob ects, advantages, and features of the present invention will become apparent from the following specification.

Detailed Description of the Invention The present inventions are directed to the discovery of a unique class of msecticidal protein toxins from the genus Photorhabdus that have oral toxicity against insects. A unique feature of Photorhabdus is its biolum escence . Photorhabdus may be isolated from a variety of sources. One such source is nematodes, more particularly nematodes of the genus Heterorhabdi is. Another such source is from human clinical samples from wounds, see Farmer et al . 1989 J Clin. Microbiol. 27 -4- SUBSTΪTUTE SHEET (RULE 26) pp. 1594-1600. These saprohytic strains are deposited m the American Type Culture Collection (Rockville, MD) ATCC #s 43948, 43949, 43950, 43951, and 43952, and are incorporated herein by reference. It is possible that other sources could harbor Photorhabdus bacteria that produce msecticidal toxins . Such sources in the environment could be either terrestrial or aquatic based. The genus Photorhabdus is taxonom cally defined as a member of the Family Enterobacteπaceae, although it has certain traits atypical of this family For example, strains of this genus are nitrate reduction negative, yellow and red pigment producing and biolummescent . This latter trait is otherwise unknown with the En t er oba ctena ceae . Photorhabdus has only recently been described as a genus separate from the Xenorhabdus (Boemare et al . , 1993 Int. J. Syst. Bacteriol . 43, 249-255). This differentiation is based on DNA-DNA hybridization studies, phenotypic differences (e.g., presence [ Photorhabdus) or absence {Xenorhabdus) of catalase and biolummescence) and the Family of the nematode host [Xenorhabdus ; Stemernejnatidae, Photorhabdus ; Heterorhabdi tidae) Comparative, cellular fatty-acid analyses (Janse et al 1990, Lett. Appl Microbiol 10, 131-135; Suzuki et al . 1990, J. Gen Appl. Microbiol., 36, 393-401) support the separation of Photorhabdus from Xenorhabdus . In order to establish that the strain collection disclosed herein was comprised of Photorhabdus strains, the strains were characterized based on recognized traits which define Photorhabdus and differentiate it from other Enterobacteπaceae and Xenorhabdus species. (Farmer, 1984 Bergey's Manual of Systemic Bacteriology Vol. 1 pp.510-511; Akhurst and Boemare 1988, J. Gen Microbiol. 134 pp. 1835-1845, Boemare et al . 1993 Int. J Syst. Bacteriol. 43 pp. 249-255, which are incorporated herein by reference) The traits studied were the following: gram stain negative rods, organism size, colony pigmentation, inclusion bodies, presence of catalase, ability to reduce nitrate, biolummescence, dye uptake, gelatin hydrolysis, growth on selective media, growth temperature, survival under anerobic conditions and motility Fatty acid analysis was used to confirm that the strains herein all belong to the single genus Photorhabdus . Currently, the bacterial genus Photorhabdus is comprised of a single defined species, Photorhabdus luminescens (ATCC Type strain #29999, Pomar et al . , 1977, Nematologica 23, 97-102). A variety of related strains have been described m the literature (e.g., Akhurst et al . 1988 J. Gen. Microbiol., 134, 1835-1845; Boemare -5- SUBSTΓΓUTE SHEET (RULE26) et al. 1993 Int. J. Syst. Bacteriol. 43 pp. 249-255; Putz et al . 1990, Appl. Environ. Microbiol., 56, 181-186) Numerous Photorhabdus strains have been characterized herein. Because there is currently only one species (luminescens) defined within the genus Photorhabdus , the luminescens species traits were used to characterize the strains herein. As can be seen m Fig. 5, these strains are quite diverse. It is not unforeseen that m the future there may be other Photorhabdus species that will have some of the attributes of the luminescens species as well as some different characteristics that are presently not defined as a trait of Photorhabdus luminescens . However, the scope of the invention herein is to any Photorhabdus species or strains which produce proteins that have functional activity as insect control agents, regardless of other traits and characteristics. Furthermore, as is demonstrated herein, the bacteria of the genus Photorhabdus produce proteins that have functional activity as defined herein. Of particular interest are proteins produced by the species Photorhabdus luminescens . The inventions herein should in no way be limited to the strains which are disclosed herein. These strains illustrate for the first time that proteins produced by diverse isolates of Photorhabdus are toxic upon exposure to insects. Thus, mcluded with the inventions described herein are the strains specified herein and any mutants thereof, as well as any strains or species of the genus Photorhabdus that have the functional activity described herein. There are several terms that are used herein that have a particular meaning and are as follows. By "functional activity" it is meant herein that the protein toxin (s) function as insect control agents in that the proteins are orally active, or have a toxic effect, or are able to disrupt or deter feeding, which may or may not cause death of the insect. When an insect comes into contact with an effective amount of toxin delivered via transgenic plant expression, formulated protein compositions (s) , sprayable protein composition (s) , a bait matrix or other delivery system, the results are typically death of the insect, or the insects do not feed upon the source which makes the toxins available to the insects. By the use of the term "genetic material" herein, it is meant to include all genes, nucleic acid, DNA and RNA. -6- SUBSTΓΓUTE SHEET (RULE 26) By "homolog" it is meant an ammo acid sequence that is identified as possessing homology to a reference W-14 tox polypeptide ammo acid sequence. By "homology" it is meant an ammo acid sequence that has a similarity index of at least 33% and/or an identity index of at least 26% to a reference W-14 toxm polypeptide am o acid sequence, as scored by the GAP algorithm using the BlOsum 62 protein scoring matrix (Wisconsin Package Version 9.0, Genetics Computer Group (GCG) , Madison, WI) . By "identity" is meant an ammo acid sequence that contains an identical residue at a given position, following alignment with a reference W-14 tox polypeptide ammo acid sequence by the GAP algorithm. The protein toxins discussed herein are typically referred to as "insecticides" By insecticides it is meant herein that the protein toxins have a "functional activity" as further defined herein and are used as insect control agents. By the use of the term "oligonucleotides" it is meant a macromolecule consisting of a short chain of nucleotides of either RNA or DNA. Such length could be at least one nucleotide, but typically are in the range of about 10 to about 12 nucleotides. The determination of the length of the oligonucleotide is well withm the skill of an artisan and should not be a limitation herein Therefore, oligonucleotides may be less than 10 or greater than 12. By the use of the term " Photorhabdus tox " it is meant any protein produced by a Photorhabdus microorganism strain which has functional activity against insects, where the Photorhabdustox could be formulated as a sprayable composition, expressed by a transgenic plant, formulated as a bait matrix, delivered via baculov rus, or delivered by any other applicable host or delivery system. By the use of the term "toxic" or "toxicity" as used herein it is meant that the toxins produced by Photorhabdus have "functional activity" as defined herein. - 7 - SUBSTTTUTE SHEET (RULE 26) By "truncated peptide" it is meant herein to include any peptide that is fragment (s) of the peptides observed to have functional activity. By "substantial sequence homology" is meant either, a DNA fragment having a nucleotide sequence sufficiently similar to another DNA fragment to produce a protein having similar biochemical properties; or a polypeptide having an am o acid sequence sufficiently similar to another polypeptide to exhibit similar biochemical properties. Fermentation broths from selected strains reported Table 20 were used to determine the following: breadth of msecticidal tox production by the Photorhabdus genus, the msecticidal spectrum of these toxins, and to provide source material to purify the toxm complexes. The strains characterized herein have been shown to have oral toxicity against a variety of insect orders Such insect orders include but are not limited to Coleoptera , Homoptera, Lepidoptera, Diptera, Acarina, Hymenoptera and Dic yoptera . As with other bacterial toxins, the rate of mutation of the bacteria in a population causes many related toxins slightly different in sequence to exist. Toxins of interest here are those which produce protein complexes toxic to a variety of insects upon exposure, as described herein Preferably, the toxins are active against Lepidoptera , Coleoptera , Ho opotera, Diptera, Hymenoptera, Di ctyoptera and Acarina . The inventions herein are intended to capture the protein toxins homologous to protein toxins produced by the strains herein and any derivative strains thereof, as well as any protein toxins produced by Photorhabdus These homologous proteins may differ in sequence, but do not differ m function from those toxins described herein. Homologous toxins are meant to include protein complexes of between 300 kDa to 2,000 kDa and are comprised of at least two (2) subunits, where a subunit is a peptide which may or may not be the same as the other subunit. Various protein subunits have been identified and are taught in the Examples herein. Typically, the protein subunits are between about 18 kDa to about 230 kDa; between about 160 kDa to about 230 kDa; 100 kDa to 160 kDa; about 80 kDa to about 100 kDa; and about 50 kDa to about 80 kDa. As discussed above, some Photorhabdus strains can be isolated from nematodes. Some nematodes, elongated cylindrical parasitic worms of the p .ylum Nematoda , have evolved an ability to exploit insect larvae as a favored growth environment The insect larvae provide a source of food for growing nematodes and an environment in which to reproduce. One dramatic effect that follows invasion of larvae by certain nematodes is larval death. Larval death results from the presence of, in certain nematodes, bacteria that produce an msecticidal tox which arrests larval growth and inhibits feeding activity. Interestingly, it appears that each genus of insect parasitic nematode hosts a particular species of bacterium, uniquely adapted for symbiotic growth with that nematode. In the interim since this research was initiated, the name of the bacterial genus Xenorhabdus was reclassified into the Xenorhabdus and the Photorhabdus . Bacteria of the genus Photorhabdus are characterized as being symbionts of Heterorhabdi tuε nematodes while Xenorhabdus species are symbionts of the Steiπernema species . This change in nomenclature is reflected in this specification, but in no way should a change in nomenclature alter the scope of the inventions described herein. The peptides and genes that are disclosed herein are named according to the guidelines recently published in the Journal of Bacteriology "Instructions to Authors" p. i -xii (Jan. 1996), which is incorporated herein by reference. The following peptides and genes were isolated from Photorhabdus strain W-14. -9- SUBSTΪTUTE SHEET (RULE 26) Table ι Peptide/Gene Nomenclature Toxm Complex "Sequence ID No.'s m brackets are peptide N-termini, b Numbers in parentheses are N-termim of internal peptide tryptic fragments =deduced from gene sequence internal gene fragment The sequences listed above are grouped by genomic region. More specifically, the Photorhabdus luminesence bacteria (W-14) has at least four distinct genomic regions- tea, tcb, tec and ted. As can be seen in Table 1, peptide products are produced from these distinct genomic regions. Furthermore, as illustrated the Examples, specifically Examples 15 and 21, individual gene products produced from three genomic regions are associated with insect activity. There is also considerable homology between these four genomic regions. -10- SUBSTΓΓUTE SHEET (RULE 26) As is further illustrated m the Examples, the tcbA gene was expressed m E. coli as two possible biological active protein fragments (TcbA and TcbAn/m) . The tcdA gene was also expressed in E. coli . As illustrated in Example 16, when the native unprocessed TcbA tox was treated with the endogeneous metalloproteases or insect gut contents containing proteases, the TcbA protein toxin was processed into smaller subunits that were less than the size of the native peptides and Southern Corn Rootworm activity increased. The smaller tox peptides remained associated as part of a tox complex. It may be desirable in some situations to increase activation of the toxm(s) by proteolytic processing or using truncated peptides. Thus, it may be more desirable to use truncated peptide (s) in some applications, i.e., commercial transgenic plant applications. In addition to the W-14 strain, there are other species withm the Photorhabdus genus that have functional activity which is differential (specifically see Tables 20 and 36) Even though there is differential activity, the amino acid sequences in some cases have substantial sequence homology. Moreover, the molecular probes indicate that some genes contained in the strains are homologous to the genes contained in the W-14 strain. In fact all of the strains illustrated herein have one or more homologs of W-14 toxm genes. The antibody data in Example 26 and the N- terminal sequence data in Example 25 further support the conclusion that there is homology and identity (based on am o acid sequence) between the protein toxm(s) produced by these strains. At the molecular level, the W-14 gene probes indicated that the homologs or the W-14 genes themselves (Tables 37, 38, and 39) are dispersed throughout the Photorhabdus genus. Further, it is possible that new toxm genes exist in other strains which are not homologous to W-14, but maintain overall protein attributes (see specifically Examples 14 and 25) . Even though there is homology or identity between toxm genes produced by the Photorhabdus strains , the strains themselves are quite diverse. Using polymerase chain reaction technology further discussed in Example 22, most of the strains illustrated herein are quite distinguishable. For example as can be seen in Figs. 5, the percentage relative similarity of some of the strains, such as HP88 and NC-1, was about 0.8, which indicates that the strains are similar, while HP88 and Hb was about 0.1, which indicates substantial diversity. Therefore, even though the insect tox genes or gene products that the strains produce are the same or similar, the strains themselves are diverse -11- SUBSTΓΓUTE SHEET (RULE 26) In view of the data further disclosed in the Examples and discussions herein, it is clear that a new and unique family of msecticidal protein toxm(s) has been discovered. It has been further illustrated herein that these toxm(s) widely exist withm bacterial strains of the Photorhabdus genus. It may also be the case that these tox genes widely exist withm the family Enterobacteracaea . Antibodies prepared as described in Example 21 or gene probes prepared as described in Example 25 may be used to further screen for bacterial strains with the family Enterobacteracaea that produce the homologous toxm(s) that have functional activity. It may also be the case that specific primer sets exist that could facilitate the identification of new genes with the Photorhabdus genus or family Enterobacteracaea . As stated above, the antibodies may be used to rapidly screen bacteria of the genus Photorhabdus or the family En erbacteracaea for homologous toxm products as illustrated in Example 26. Those skilled in the art are quite familiar with the use of antibodies as an analysis or screening tool (see US Patent No. 5,430,137, which is incorporated herein by reference) . Moreover, it is generally accepted in the literature that antibodies are elicited against 6 to 20 ammo acid residue segments that tend to occupy exposed surface of polypeptides (Current Protocols in Immunology, Coligan et al, National Institutes of Health, John Wiley & Sons, Inc.) Usually the ammo acid consist of contiguous am o acid residues, however, m certain cases they may be formed by non-contiguous ammo acids that are constrained by specific conformation. The ammo acid segments recognized by antibodies are highly specific and commonly referred to epitopes. The ammo acid fragment can be generated by chemical and/or enzymatic cleavage of the native protein, by automated, " solid-phase peptide synthesis, or by production from genetic engineering organisms. Polypeptide fragments- can be isolated by a variety and/or combination of HPLC and FPLC chromatographic methods known in the art. Selection of polypeptide fragment can be aided by the use of algorithms, for example Kyte and Doolittle, 1982, Journal of Molecular Biology 157: 105-132 and Chou and Fasman, 1974, Biochemistry 13: 222-245, that predict those sequences most likely to exposed on the surface of the protein. For preparation of immunogen containing the polypeptide fragment of interest, in general, polypeptides are covalently coupled using chemical reactions to carrier proteins such as keyhole limpet hemocyanm via free amino (lysiπe) , sulfhydyl (cysteine) , phenolic (tyrosme) or carboxylic (aspartate or glutamate) groups. Immunogen with an adjuvant is injected n animals, such as mice or rabbits, or -12- SUBSTΓΠJTE SHEET (RULE 26) chickens to elicit an immune response against the immunogen Analysis of antibody titer in antisera of inject animals against polypeptide fragment can be determined by a variety of immunological methods such as ELISA and Western blot. Alternatively, monoclonal antibodies can be prepared using spleen cells of the injected animal for fusion with tumor cells to produce immortalized hybndomas cells producing a single antibody species. Hybndomas cells are screened using immunological methods to select lines that produce a specific antibody to the polypeptide fragment of interest. Purification of antibodies from different sources can be performed by a variety of antigen affinity or antibody affinity columns or other chromatographic HPLC or FPLC methods. The toxins described herein are quite unique in that the toxins have functional activity, which is key to developing an insect management strategy In developing an insect management strategy, it is possible to delay or circumvent the protein degradation process by injecting a protein directly into an organism, avoiding its digestive tract. In such cases, the protein administered to the organism will retain its function until it is denatured, non-specifically degraded, or eliminated by the immune system in higher organisms. Injection into insects of an msecticidal toxm has potential application only in the laboratory, and then only on large insects which are easily in j ected. The observation that the msecticidal protein toxins herein described exhibits their toxic activity after oral gestion or contact with the toxins permits the development of an insect management plan based solely on the ability to incorporate the protein toxins into the insect diet. Such a plan could result m the production of insect baits. The Photorhabdus toxins may be administered to insects a purified form. The toxins may also be delivered in amounts from about 1 to about 100 mg / liter of broth. This may vary upon formulation condition, conditions of the inoculum source, techniques for isolation of the toxm, and the like. The toxins may be administered as an exudate secretion or cellular protein originally expressed in a heterologous prokaryotic or eukaryotic host Bacteria are typically the hosts in which proteins are expressed. Eukaryotic hosts could include but are not limited to plants, insects and yeast. Alternatively, the toxins may be produced in bacteria or transgenic plants in the field or in the insect by a baculovirus vector. Typically the toxins will be introduced to the insect by incorporating one or more of the toxins into the insects' feed -13- SUBSTΓΓUTE SHEET (RULE 26) Complete lethality to feeding insects is useful but is not required to achieve useful toxicity. If the insects avoid the toxm or cease feeding, that avoidance will be useful m some applications, even if the effects are sublethal . For example, if insect resistant transgenic crop plants are desired, a reluctance of insects to feed on the plants is as useful as lethal toxicity to the insects since the ultimate objective is protection of the plants rather than killing the insect. There are many other ways in which toxins can be incorporated into an insect's diet. As an example, it is possible to adulterate the larval food source with the toxic protein by spraying the food with a protein solution, as disclosed herein. Alternatively, the purified protein could be genetically engineered into an otherwise harmless bacterium, which could then be grown in culture, and either applied to the food source or allowed to reside m the soil in an area m which insect eradication was desirable. Also, the protein could be genetically engineered directly into an insect food source. For instance, the major food source of many insect larvae is plant material. By incorporating genetic material that encodes the msecticidal properties of the Photorhabdus toxins into the genome of a plant eaten by a particular insect pest, the adult or larvae would die after consuming the food plant. Numerous members of the monocotyledonous and dictyledenous genera have been transformed. Transgenic agronmonic crops as well as fruits and vegetables are of commercial interest. Such crops include but are not limited to maize, rice, soybeans, canola, sunflower, alfalfa, sorghum, wheat, cotton, peanuts, tomatoes, potatoes, and the like. Several techniques exist for introducing foreign genetic material into plant cells, and for obtaining plants that stably maintain and express the introduced gene. Such techniques include acceleration of genetic material coated onto icroparticles directly into cells (U.S. Patents 4,945,050 to Cornell and 5,141,131 to DowElanco) . Plants may be transformed using Agrrobacterium technology, see U.S. Patent 5,177,010 to University of Toledo, 5,104,310 to Texas A&M, European Patent Application 0131624B1, European Patent Applications 120516, 159418B1 and 176,112 to Schilperoot, U.S. Patents 5,149,645, 5,469,976, 5,464,763 and 4,940,838 and 4,693,976 to Schilperoot, European Patent Applications 116718, 290799, 320500 all to MaxPlanck, European Patent Applications 604662 and 627752 to Japan Tobacco, European Patent Applications 0267159, and 0292435 and U.S. Patent 5,231,019 all to Ciba Ge gy, U.S Patents 5,463,174 and 4,762,785 both to Calgene, and U.S. Patents 5,004,863 and -14- SUBSTΓΓUTE SHEET (RULE 25) 5,159,135 both to Agracetus . Other transformation technology includes whiskers technology, see U.S. Patents 5,302,523 and 5,464,765 both to Zeneca. Electroporation technology has also been used to transform plants, see WO 87/06614 to Boyce Thompson Institute, 5,472,869 and 5,384,253 both to Dekalb, WO9209696 and W09321335 both to PGS . All of these transformation patents and publications are incorporated by reference. In addition to numerous technologies for transforming plants, the type of tissue which is contacted with the foreign genes may vary as well. Such tissue would include but would not be limited to embryogenic tissue, callus tissue type I and II, hypocotyl , meristem, and the like. Almost all plant tissues may be transformed during dedifferentiation using appropriate techniques withm the skill of an artisan. Another variable is the choice of a selectable marker. The preference for a particular marker is at the discretion of the artisan, but any of the following selectable markers may be used along with any other gene not listed herein which could function as a selectable marker. Such selectable markers include but are not limited to ammoglycoside phosphotransferase gene of transposon Tn5 (Aph II) which encodes resistance to the antibiotics kana ycm, neomycm and G418, as well as those genes which code for resistance or tolerance to glyphosate; hygromycm; methotrexate; phosphmothric (bialophos) ; lmidazolmones, sulfonylureas and triazolopyrimidme herbicides, such as chlorosulfuron,- bromoxynil, dalapon and the like. In addition to a selectable marker, it may be desirous to use a reporter gene . In some instances a reporter gene may be used without a selectable marker. Reporter genes are genes which are typically not present or expressed in the recipient organism or tissue. The reporter gene typically encodes for a protein which provides for some phenotypic change or enzymatic property Examples of such genes are provided in K. Weismg et al . Ann. Rev. Genetics, 22, 421 (1988), which is incorporated herein by reference. A preferred reporter gene is the glucuronidase (GUS) gene . Regardless of transformation technique, the gene is preferably incorporated into a gene transfer vector adapted to express the Photorhabdus toxins in the plant cell by including m the vector a plant promoter. In addition to plant promoters, promoters from a variety of sources can be used efficiently in plant cells to express foreign genes. For example, promoters of bacterial origin, such as the octop e synthase promoter, the nopalme synthase -15- SUBSTΪTUTE SHEET (RULE 26) promoter, the marmop e synthase promoter; promoters of viral origin, such as the cauliflower mosaic virus (35S and 19S) , reengineered 35S, known as 35T (see PCT/US96/16582 , WO 97/13402 published April 17, 1997, which is incorporated herein by reference) and the like may be used. Plant promoters include, but are not limited to rιbulose-1 , 6-bιsphosphate (RUBP) carboxylase small subunit (ssu) , beta-conglyc in promoter, phaseolm promoter, ADH promoter, heat-shock promoters and tissue specific promoters. Promoters may also contain certain enhancer sequence elements that may improve the transcription efficiency. Typical enhancers include but are not limited to Adh-mtron 1 and Adh- intron 6 Constitutive promoters may be used. Constitutive promoters direct continuous gene expression in all cells types and at all times (e.g., act , ubiquitin, CaMV 35S) Tissue specific promoters are responsible for gene expression specific cell or tissue types, such as the leaves or seeds (e.g., zein, oleosin, napin, ACP) and these promoters may also be used. Promoters may also be are active during a certain stage of the plants' development as well as active in plant tissues and organs. Examples of such promoters include but are not limited to pollen-specific, embryo specific, corn silk specific, cotton fiber specific, root specific, seed endosperm specific promoters and the like. Under certain circumstances it may be desirable to use an mducible promoter. An mducible promoter is responsible for expression of genes in response to a specific signal, such as. physical stimulus (heat shock genes) , light (RUBP carboxylase) ; hormone (Em); metabolites, and stress. Other desirable transcription and translation elements that function plants may be used. Numerous plant-specific gene transfer vectors are known to the art. In addition, it is known that to obtain high expression of bacterial genes plants it is preferred to reeng eer the bacterial genes so that they are more efficiently expressed the cytoplasm of plants. Maize is one such plant where it is preferred to reengmeer the bacterial gene(s) prior to transformation to increase the expression level of the tox in the plant One reason for the reeng eer g is the very low G+C content of the native bacterial gene(s) (and consequent skewing towards high A+T content) This results in the generation of sequences mimicking or duplicating plant gene control sequences that are known to be highly A+T rich. The presence of some A+T-rich sequences within the DNA of the gene(s) introduced into plants (e.g , TATA box regions normally found in gene promoters) may result in aberrant -16- SUBSTΓΓUTE SHEET (RULE 26) transcription of the gene(s) . On the other hand, the presence of other regulatory sequences residing in the transcribed mRNA (e.g., polyadenylation signal sequences (AAUAAA) , or sequences complementary to small nuclear RNAs involved in pre-mRNA splicing) may lead to RNA instability. Therefore, one goal in the design of reengmeered bacterial gene(s), more preferably referred to as plant optimized gene(s) , is to generate a DNA sequence having a higher G+C content, and preferably one close to that of plant genes coding for metabolic enzymes. Another goal m the design of the plant optimized gene(s) is to generate a DNA sequence that not only has a higher G+C content, but by modifying the sequence changes, should be made so as to not hinder translation. An example of a plant that has a high G+C content is maize. The table below illustrates how high the G+C content is in maize. As in maize, it is thought that G+C content n other plants is also high. Table 2 Compilation of G+C Contents of Protein Coding Regions of Maize Genes Number of genes in class given in parentheses. Standard deviations given in parentheses. Combined groups mean ignored calculation of overall mean. ■ 17 - SUBSTΓΠJTE SHEET (RULE 26) For the data in Table 2 , coding regions of the genes were extracted from GenBank (Release 71) entries, and base compositions were calculated using the MacVector™ program (IBI, New Haven, CT) . Intron sequences were ignored in the calculations. Group I and II storage protein gene sequences were distinguished by their marked difference m base composition. Due to the plasticity afforded by the redundancy of the genetic code (i.e., some am o acids are specified by more than one codon) , evolution of the genomes of different organisms or classes or organisms has resulted in differential usage of redundant codons. This "codon bias" is reflected in the mean base composition of protein coding regions. For example, organisms with relatively low G+C contents utilize codons having A or T in the third position of redundant codons, whereas those having higher G+C contents utilize codons having G or C in the third position. It is thought that the presence of "minor" codons withm a gene's mRNA may reduce the absolute translation rate of that mRNA, especially when the relative abundance of the charged tRNA corresponding to the minor codon is low. An extension of this is that the diminution of translation rate by individual minor codons would be at least additive for multiple minor codons. Therefore, mRNAs having high relative contents of minor codons would have correspondingly low translation rates. This rate would be reflected by the synthesis of low levels of the encoded protein. In order to reengmeer the bacterial genets), the codon bias of the plant is determined. The codon bias is the statistical codon distribution that the plant uses for coding its proteins After determining the bias, the percent frequency of the codons in the gene(s) of interest is determined. The primary codons preferred by the plant should be determined as well as the second and third choice of preferred codons . The amino acid sequence of the protein of interest is reverse translated so that the resulting nucleic acid sequence codes for the same protein as the native bacterial gene, but the resulting nucleic acid sequence corresponds to the first preferred codons of the desired plant The new sequence is analyzed for restriction enzyme sites that might have been created by the modification. The identified sites are further modified by replacing the codons with second or third choice preferred codons. Other sites in the sequence which could affect the transcription or translation of the gene of interest are the exon -.intron 5' or 3 ' junctions, poly A addition signals, or RNA polymerase termination signals. The sequence is further analyzed and modified to reduce the frequency of TA or GC doublets In - 18 - SUBSTΓΓUTE SHEET (RULE 26) addition to the doublets, G or C sequence blocks that have more than about four residues that are the same can affect transcription of the sequence. Therefore, these blocks are also modified by replacing the codons of first or second choice, etc. with the next preferred codon of choice. It is preferred that the plant optimized genets) contains about 63% of first choice codons, between about 22% to about 37% second choice codons, and between 15% and 0% third choice codons, wherein the total percentage is 100%. Most preferred the plant optimized gene(s) contain about 63% of first choice codons, at least about 22% second choice codons, about 7.5% third choice codons, and about 7.5% fourth choice codons, wherein the total percentage is 100%. The method described above enables one skilled in the art to modify gene(s) that are foreign to a particular plant so that the genes are optimally expressed in plants The method is further illustrated application PCT/US96/16582 , WO 97/13402 published April 17, 1997 Thus, in order to design plant optimized gene(s) the ammo acid sequence of the toxins are reverse translated into a DNA sequence, utilizing a nonredundant genetic code established from a codon bias table compiled for the gene DNA sequence for the particular plant being transformed The resulting DNA sequence, which is completely homogeneous in codon usage, is further modified to establish a DNA sequence that, besides having a higher degree of codon diversity, also contains strategically placed restriction enzyme recognition sites, desirable base composition, and a lack of sequences that might interfere with transcription of the gene, or translation of the product mRNA. It is theorized that bacterial genes may be more easily expressed n plants if the bacterial genes are expressed in the plastids. Thus, it may be possible to express bacterial genes in plants, without optimizing the genes for plant expression, and obtain high express of the protein. See U.S. Patent Nos. 4,762,785; 5,451,513 and 5,545,817, which are incorporated herein by reference. One of the issues regarding commercial exploiting transgenic plants is resistance management. This is of particular concern with Bacillus thuringiensis toxins. There are numerous companies commeπcally exploiting Bacillus thuringiensis and there has been much concern about Bt toxins becoming resistant. One strataegy for insect resistant management would be to combine the toxins produced by Photorhabdus with toxins such as Bt, vegetative insect proteins (Ciba Geigy) or other toxins. The combinations could be formulated -19- SUBSTΪTUTE SHEET (RULE 26) for a sprayable application or could be molecular combinations. Plants could be transformed with Photorhabdus genes that produce insect toxins and other insect toxm genes such as Bt as with other insect tox genes such as Bt. European Patent Application 0400246A1 describes transformation of 2 Bt m a plant, which could be any 2 genes. Another way to produce a transgenic plant that contains more than one insect resistant gene would be to produce two plants, with each plant containing an insect resistant gene. These plants would be backcrossed using traditional plant breeding techniques to produce a plant containing more than one insect resistant gene. In addition to producing a transformed plant containing plant optimized gene(s), there are other delivery systems where it may be desirable to reengmeer the bacterial gene(s) Along the same lines, a genetically engineered, easily isolated protein tox fusing together both a molecule attractive to insects as a food source and the msecticidal activity of the toxin may be engineered and expressed in bacteria or m eukaryotic cells using standard, well-known techniques. After purification in the laboratory such a toxic agent with "built-in" bait could be packaged inside standard insect trap housings. Another delivery scheme is the incorporation of the genetic material of toxins into a baculovirus vector Baculoviruses infect particular insect hosts, including those desirably targeted with the Photorhabdus toxins. Infectious baculovirus harboring an expression construct for the Photorhabdus toxins could be introduced into areas of insect infestation to thereby intoxicate or poison infected insects. Transfer of the msecticidal properties requires nucleic acid sequences encoding the coding the ammo acid sequences for the Photorhabdus toxins integrated into a protein expression vector appropriate to the host in which the vector will reside. One way to obtain a nucleic acid sequence encoding a protein with msecticidal properties is to isolate the native genetic material which produces the toxins from Photorhabdus, using information deduced from the toxin's ammo acid sequence, large portions of which are set forth below. As described below, methods of purifying the proteins responsible for tox activity are also disclosed. Using N-terminal ammo acid sequence data, such as set forth below, one can construct oligonucleotides complementary to all, or a section of, the DNA bases that encode the first am o acids of the tox . These oligonucleotides can be radiolabeled and used as -20- SUBSTΓΓUTE SHEET (RULE 26) molecular probes to isolate the genetic material from a genomic genetic library built from genetic material isolated from strains of Photorhabdus. The genetic library can be cloned in plasmid, cosmid, phage or phagemid vectors. The library could be transformed into Escherichia coli and screened for toxm production by the transformed cells using antibodies raised against the tox or direct assays for insect toxicity. This approach requires the production of a battery of oligonucleotides, since the degenerate genetic code allows an ammo acid to be encoded the DNA by any of several three-nucleotide combinations. For example, the ammo acid argmme can be encoded by nucleic acid triplets CGA, CGC, CGG, CGT, AGA, and AGG. Since one cannot predict which triplet is used at those positions the tox gene, one must prepare oligonucleotides with each potential triplet represented. More than one DNA molecule corresponding to a protein subunit may be necessary to construct a sufficient number of oligonucleotide probes to recover all of the protein subunits necessary to achieve oral toxicity. From the am o acid sequence of the purified protein, genetic materials responsible for the production of toxms can readily be isolated and cloned, in whole or in part, into an expression vector using any of several techniques well-known to one skilled in the art of molecular biology A typical expression vector is a DNA plasmid, though other transfer means including, but not limited to, cosmids, phagemids and phage are also envisioned. In addition to features required or desired for plasmid replication, such as an origin of replication and antibiotic resistance or other form of a selectable marker such as the bar gene of Streptomyces hygroscopicus or viπdochromogenes, protein expression vectors normar-ly additionally require an expression cassette which incorporates the cis-actmg sequences necessary fcrr-tr-anscription and translation of the gene of interest The cis-actmg sequences required for expression in prokaryotes differ from those required in eukaryotes and plants. A eukaryotic expression cassette requires a transcriptional promoter upstream (5') to the gene of interest, a transcriptional termination region such as a poly-A addition site, and a ribosome binding site upstream of the gene of interest's first codon. In bacterial cells, a useful transcriptional promoter that could be mcluded in the vector is the T7 RNA Polymerase-binding promoter. Promoters, as previously described herein, are known to efficiently promote transcription of mRNA Also upstream from the gene of interest the vector may include a nucleotide sequence encoding a -21- SUBSTΓΓUTE SHEET (RULE 26) signal sequence known to direct a covalently linked protein to a particular compartment of the host cells such as the cell surface. Insect viruses, or baculoviruses, are known to infect and adversely affect certain insects. The affect of the viruses on insects is slow, and viruses do not stop the feeding of insects. Thus viruses are not viewed as being useful as insect pest control agents . Combining the Photorhabdus toxins genes into a baculovirus vector could provide an efficient way of transmitting the toxins while increasing the lethality of the virus. In addition, since different baculoviruses are specific to different insects, it may be possible to use a particular toxin to selectively target particularly damaging insect pests. A particularly useful vector for the toxins genes is the nuclear polyhedrosis virus. Transfer vectors using this virus have been described and are now the vectors of choice for transferring foreign genes into insects. The virus-toxin gene recombinant may be constructed in an orally transmissible form. Baculoviruses normally infect insect victims through the mid-gut intestinal mucosa. The toxin gene inserted behind a strong viral coat protein promoter would be expressed and should rapidly kill the infected insect. In addition to an insect virus or baculovirus or transgenic plant delivery system for the protein toxins of the present invention, the proteins may be encapsulated using Bacillus thuringiensis encapsulation technology such as but not limited to U.S. Patent Nos. 4,695,455; 4,695,462; 4,861,595 which are all incorporated herein by reference. Another delivery system for the protein toxins of the present invention is formulation of the protein into a bait matrix, which could then be used in above and below ground insect bait stations. Examples of such technology include but are not limited to PCT Patent Application WO 93/23998, which is incorporated herein by reference. As is described above, it might become necessary to modify the sequence encoding the protein when expressing it in a non-native host, since the codon preferences of other hosts may differ from that of Photorhabdus . In such a case, translation may be quite inefficient in a new host unless compensating modifications to the coding sequence are made. Additionally, modifications to the amino acid sequence might be desirable to avoid inhibitory cross - reactivity with proteins of the new host, or to refine the insecticidal properties of the protein in the new host. A genetically modified toxin gene might encode a toxin exhibiting, for example, enhanced or reduced toxicity, altered insect -22- SUBSTΓΓUTE SHEET (RULE 26) resistance development, altered stability, or modified target species specificity. In addition to the Photorhabdus genes encoding the toxins, the scope of the present invention is intended to include related nucleic acid sequences which encode ammo acid biopolymers homologous to the toxm proteins and which retain the toxic effect of the Photorhabdus proteins in insect species after oral mgestion. For instance, the toxms used in the present invention seem to first inhibit larval feeding before death ensues. By manipulating the nucleic acid sequence of Photorhabdus toxms or its controlling sequences, genetic engineers placing the tox gene into plants could modulate its potency or its mode of action to, for example, keep the eating- inhibitory activity while eliminating the absolute toxicity to the larvae. This change could permit the transformed plant to survive until harvest without having the unnecessarily dramatic effect on the ecosystem of wiping out all target insects. All such modifications of the gene encoding the toxm, or of the protein encoded by the gene, are envisioned to fall withm the scope of the present invention. Other envisioned modifications of the nucleic acid include the addition of targeting sequences to direct the toxm to particular parts of the insect larvae for improving its efficiency.

Example ι Purification of Tox from Photorhabdus luminescens and Demonstration of Toxicity after Oral Delivery of Purified Toxm The msecticidal protein toxm of the present invention was purified from Photorhabdus luminescens strain W-14, ATCC Accession Number 55397 Stock cultures of Photorhabdus luminescens were maintained on petri dishes containing 2% Proteose Peptone No. 3 (i.e., PP3, Difco Laboratories, Detroit MI) in 1.5% agar, incubated at 25°C and transferred weekly. Colonies of the primary form of the bacteria were inoculated into 200 ml of PP3 broth supplemented with 0.5% polyoxyethylene sorbitan mono-stearate (Tween 60, Sigma Chemical Company, St. Louis, MO) in a one liter flask. The broth cultures were grown for 72 hours at 30°C on a rotary shaker. The toxm proteins can be recovered from cultures grown in the presence or absence of Tween,- however, the absence of Tween can affect the form of the bacteria grown and the profile of proteins produced by the bacteria. In the absence of Tween, a variant shift occurs insofar as the molecular weight of at least one identified toxm subunit shifts from about 200 kDa to about 185 kDa. The 72 hour cultures were centrifuged at 10,000 x g for 30 minutes to remove cells and debris The supernatant fraction that contained the msecticidal activity was decanted and brought to 50 mM K 2 HPO„ by adding an appropriate volume of 1.0 M K ^ HPO, . The pH was acfjuste<3 to 8.6 by adding potassium hydroxide. This supernatant fraction was then mixed with DEAE-Sephace-z (Pharmacia LKB Biotechnology) which had been equilibrated with 50 mM K 2 HP0 4 . The toxic activity was adsorbed to the DEAE resin. This mixture was then poured into a 2.6 x 40 cm column and washed with 50 mM K 2 HP0 4 at room temperature at a flow rate of 30 l/hr until the effluent reached a steady baseline UV absorbance at 280 nm. The column was then washed with 150 mM KC1 until the effluent again reached a steady 280 nm baseline. Finally the column was washed with 300 mM KC1 and fractions were collected. Fractions containing the toxin were pooled and filter sterilized using a 0.2 micron pore membrane filter The toxm was then concentrated and equilibrated to 100 mM KP0 4 , pH 6.9, using an ultraflltration membrane with a molecular weight cutoff of 100 kDa -24- SUBSTΓΓUTE SHEET (RULE 26) at 4°C (Centπprep 100, Amicon Division-W.R. Grace and Company). A 3 ml sample of the toxin concentrate was applied to the top of a 2.6 x 95 cm Sephacryl S-400 HR gel filtration column (Pharmacia LKB Biotechnology) . The eluent buffer was 100 mM KP0„, pH 6.9, which was run at a flow rate of 17 ml/hr, at 4°C The effluent was monitored at 280 nm. Fractions were collected and tested for toxic activity. Toxicity of chromatographic fractions was examined m a biological assay using Manduca sexta larvae. Fractions were either applied directly onto the insect diet (Gypsy moth wheat germ diet, ICN Biochemicals Division - ICN Biomed cals, Inc.) or administered by mtrahemocelic injection of a 5 μl sample through the first proleg of 4th or 5th instar larva using a 30 gauge needle. The weight of each larva withm a treatment group was recorded at 24 hour intervals. Toxicity was presumed if the insect ceased feeding and died with several days of consuming treated insect diet or if death occurred withm 24 hours after injection of a fraction. The toxic fractions were pooled and concentrated using the Centrιprep-100 and were then analyzed by HPLC using a 7.5 mm x 60 cm TSK-GEL G-4000 SW gel permeation column with 100 mM potassium phosphate, pH 6.9 eluent buffer running at 0 4 ml/min. This analysis revealed the toxm protein to be contained with a single sharp peak that eluted from the column with a retention time of approximately 33 6 minutes. This retention time corresponded to an estimated molecular weight of 1,000 kDa. Peak fractions were collected for further purification while fractions not containing this protein were discarded. The peak eluted from the HPLC absorbs UV light at 218 and 280 nm but did not absorb at 405 nm. Absorbance at 405 nm was shown to be an attribute of xenorhabdm antibiotic compounds. Electrophoresis of the pooled peak fractions m a non- denaturing agarose gel (Metaphor Agarose, FMC BioProducts) showed that two protein complexes are present in the peak. The peak material, buffered in 50 mM Tris-HCl, pH 7.0, was separated on a 1.5% agarose stacking gel buffered with 100 mM Tris-HCl at pH 7.0 and 1.9% agarose resolving gel buffered with 200 mM Tris-borate at pH 8.3 under standard buffer conditions (anode buffer 1M Tris-HCl, pH 8.3; cathode buffer 0.025 M Tris, 0.192 M glycme) . The gels were run at 13 mA constant current at 15°C until the phenol red tracking dye reached the end of the gel. Two protein bands were visualized in the agarose gels using Coomassie brilliant blue staining -25- SUBSTΓΓUTE SHEET (RULE 26) The slower migrating band was referred to as "protein band 1" and faster migrating band was referred to as "protein band 2." The two protein bands were present m approximately equal amounts . The Coomassie stained agarose gels were used as a guide to precisely excise the two protein bands from unstained portions of the gels. The excised pieces containing the protein bands were macerated and a small amount of sterile water was added. As a control, a portion of the gel that contained no protein was also excised and treated the same manner as the gel pieces containing the protein. Protein was recovered from the gel pieces by electroelution into 100 mM Tris-borate pH 8.3, at 100 volts (constant voltage) for two hours. Alternatively, protein was passively eluted from the gel pieces by adding an equal volume of 50 mM Tris-HCl, pH 7.0, to the gel pieces, then incubating at 30 °C for 16 hours. This allowed the protein to diffuse from the gel into the buffer, which was then collected. Results of insect toxicity tests using HPLC-purifled toxm (33.6 mm. peak) and agarose gel purified tox demonstrated toxicity of the extracts. Injection of 1.5 μg of the HPLC purified protein kills with 24 hours. Both protein bands 1 and 2, recovered from agarose gels by passive elution or electroelution, were lethal upon injection. The protein concentration estimated for these samples was less than 50 ng/larva. A comparison of the weight gam and the mortality between the groups of larvae injected with protein bands 1 or 2 indicate that protein band 1 was more toxic by injection delivery. When HPLC-purifled toxm was applied to larval diet at a concentration of 7.5 μg/larva, it caused a halt m larval weight gam (24 larvae tested) . The larvae begin to feed, but after consuming only a very small portion of the toxm treated diet they began to show pathological symptoms induced by the toxm and the larvae cease feeding. The insect frass became discolored and most larva showed signs of diarrhea. Significant insect mortality resulted when several 5 μg toxm doses were applied to the diet over a 7-10 day period. Agarose-separated protein band 1 significantly inhibited larval weight gam at a dose of 200 ng/larva. Larvae fed similar concentrations of protein band 2 were not inhibited and gained weight at the same rate as the control larvae . Twelve larvae_were fed eluted protein and 45 larvae were fed protem-contam g agarose pieces. These two sets of data indicate that protein band 1 was orally toxic to Manduca sexta . In this experiment it appeared that protein b aid 2 was not toxic to Manduca sexta -26- SUBSTΓΠJTE SHEET (RULE 26) Further analysis of protein bands 1 and 2 by SDS-PAGE under denaturing conditions showed that each band was composed of several smaller protein subunits. Proteins were visualized by Coomassie brilliant blue staining followed by silver staining to achieve maximum sensitivity. The protein subunits in the two bands were very similar. Protein band 1 contains 8 protein subunits of 25.1, 56.2, 60.8, 65.6, 166, 171, 184 and 208 kDa Protein band 2 had an identical profile except that the 25.1, 60.8, and 65.6 kDa proteins were not present. The 56.2, 60.8, 65.6, and 184 kDa proteins were present in the complex of protein band 1 at approximately equal concentrations and represent 80% or more of the total protein content of that complex. The native HPLC-purifled toxm was further characterized as follows. The toxm was heat labile in that after being heated to 60°C for 15 minutes it lost its ability to kill or to inhibit weight gam when injected or fed to Manduca sexta larvae Assays were designed to detect lipase, type C phospholipase, nuclease or red blood cell hemolysis activities and were performed with purified toxin. None of these activities were present. Antibiotic zone inhibition assays were also done and the purified toxin failed to inhibit growth of Gram-negative or -positive bacteria, yeast or filamentous fungi, indicating that the toxic is not a xenorhabd antibiotic. The native HPLC-purifled tox was tested for ability to kill insects other than Manduca sexta Table 3 lists insects killed by the HPLC-purifled Photorhabdus luminescens toxin in this study. Table 3 Insects Killed by Photorhabdus luminescens Toxm Genus and Route of Common Name Order species Delivery Tobacco Lepidoptera Manduca sexta Oral and horn worm in ected Mealworm Coleoptera Tenebrio mol i tor Oral Pharaoh ant Hymenoptera Mono orium pharoanis Oral German Dictyoptera Blattella germanica Oral and cockroach injected Mosquito Diptera Aedes aegypti Oral -27- SUBSTΓΓUTE SHEET (RULE 26) Further Characterization of the High Molecular Weight Toxin Complex In yet further analysis, the tox protein complex was subjected to further characterization from W-14 growth medium The culture conditions and initial purification steps through the S-400 HR column were identical to those described above After isolation of the high molecular weight toxm complex from the S-400 HR column fractions, the toxic fractions were equilibrated with 10 mM Tris- HCl, pH 8.6, and concentrated in the centriplus 100 (Amicon) concentrators The protein toxin complex was then applied to a weak anion exchange (WAX) column, Vydac 301VPH575 (Hesparia, CA) , at a flow rate of 0.5 ml/mm. The proteins were eluted with a linear potassium chloride gradient, 0-250 mM KC1 , in 10 mM Tris-HCl pH 8.6 for 50 mm. Eight protein peaks were detected by absorbance at 280 nm. Bioassays using neonate southern corn rootworm (JDϊabrotαca undeci punctata howardi , SCR) larvae and tobacco horn worm [Manduca sexta , THW) were performed on all fractions eluted from the HPLC column. THW were grown on Gypsy Moth wheat germ diet (ICN) at 25 ϋ C with a 16 hr light 8 hr dark cycle. SCR were grown on Southern Corn Rootworm Larval Insecta-Diet (BioServ) at 25°C with a 16 hr light / 8 hr dark cycle. The highest mortality for SCR and THW larvae was observed for peak 6, which eluted with ca. 112 mM to 132mM KC1 SDS-PAGE analysis of peak 6 showed predominant peptides of 170 kDa, 66 kDa, 63 kDa, 59.5 kDa and 31 kDa. Western blot analysis was performed on peak 6 protein fraction with a mixture of polyclonal antibodies made against TcaA 11 -syn, TcaA 111 -syn, TcaB ι;L -syn, TcaC-syn, and TcbA 11 -syn peptides (described Example 21) and C5F2, a monoclonal antibody against the TcbA lxl peptide. Peak 6 contained immuno-reactive bands of 170 kDa, 90 kDa, 66 kDa, 59.5 kDa and 31 kDa These are very close to the predicted sizes for the TcaC (166 kDa) , TcaA li + TcaA xll (92 kDa), TcaA xll (66 kDa), TcaB ι;L (60 kDa) and TcaA ι;L (25 kDa), respectively Peak 6 which was further analyzed by native agarose gel electrophoresis, as described herein, migrated as a single band with similar mobility to that of band 1. The protein concentration of the purified peak 6 tox protein was determined using the BCA reagents (Pierce) Dilutions of the protein were made in 10 mM Tris, pH 8.6 and applied to the diet bioassays. After 240 hours all neonate larvae on diet bioassays that received ng or greater of the peak 6 protein fraction were dead. The grou of larvae that received 90 ng of the same fraction -28- SUBSTΓΓUTE SHEET (RULE 26) had 40% mortality. After 240 hrs the survivors that received 90 ng and 20 ng of peak 6 protein fraction were ca. 10% and 70%, respectively, of the control weight. Example 2 Insecticide Utility The Photorhabdus luminescens utility and toxicity were further characterized. Photorhabdus luminescens (strain W-14) culture broth was produced as follows. The production medium was 2% Bacto Proteose Peptone ® Number 3 (PP3, Difco Laboratories, Detroit, Michigan) in Milli-Q * deionized water. Seed culture flasks consisted of 175 ml medium placed in a 500 ml tribaffled flask with a Delong neck, covered with a Kaput and autoclaved for 20 minutes, T=250°F. Production flasks consisted of 500 mis in a 2.8 liter 500 ml tribaffled flask with a Delong neck, covered by a Shm-etsu silicon foam closure These were autoclaved for 45 minutes, T=250 ° F The seed culture was incubated at 28°C at 150 rpm in a gyrotory shaking incubator with a 2 inch throw. After 16 hours of growth, 1% of the seed culture was placed in the production flask which was allowed to grow for 24 hours before harvest Production of the toxm appears to be during log phase growth The microbial broth was transferred to a IL centrifuge bottle and the cellular biomass was pelleted (30 minutes at 2500 RPM at 4 ° C, [R.C.F = about 1600] HG-4L Rotor RC3 Sorval centrifuge, Dupont , Wilmington, DE) . The primary broth was chilled at 4°C for 8 - 16 hours and recentπfuged at least 2 hours (conditions above) to further clarify the broth by removal of a putative mucopolysaccharide which precipitated upon standing. (An alternative processing method combined both steps and involved the use of a 16 hour clarification centrifugation, same conditions as above.) This o broth was then stored at 4 C prior to bioassay or filtration. Photorhabdus culture broth and protein toxm(s) purified from this broth showed activity (mortality and/or growth inhibition, reduced adult emergence) against a number of insects More specifically, the activity is seen against corn rootworm (larvae and adult) , Colorado potato beetle, and turf grubs, which are members of the insect order Coleoptera . Other members of the Coleoptera include wireworms, pollen beetles, flea beetles, seed beetles and weevils. Activity has also been observed against aster leafhopper, which is a member of the order, Homoptera Other members of the Homoptera include planthoppers, pear pyslla, apple -29- SUBSTΓΓUTE SHEET (RULE 26) sucker, scale insects, whiteflies, and spittle bugs, as well as numerous host specific aphid species. The broth and purified fractions are also active against beet armyworm, cabbage looper, black cutworm, tobacco budworm, European corn borer, corn earworm, and codling moth, which are members of the order Lepidoptera . Other typical members of this order are clothes moth, Indian mealmoth, leaf rollers, cabbage worm, cotton bollworm, bagworm, Eastern tent caterpillar, sod webworm, and fall armyworm Activity is also seen against fruitfly and mosquito larvae, which are members of the order Diptera. Other members of the order Diptera are pea midge, carrot fly, cabbage root fly, turnip root fly, onion fly, crane fly, house fly, and various mosquito species. Activity is seen against carpenter ant and Argentine ant, which are members of the order that also includes fire ants, oderous house ants, and little black ants. The broth/fraction is useful for reducing populations of insects and were used in a method of inhibiting an insect population. The method may comprise applying to a locus of the insect an effective insect inactivating amount of the active described. Results are reported in Table 4. Activity against corn rootworm larvae was tested as follows. Photorhabdus culture broth (filter sterilized, cell-free) or purified HPLC fractions were applied directly to the surface (about 1.5 cm 2 ) of 0.25 ml of artificial diet in 30 μl aliquots following dilution in control medium or 10 mM sodium phosphate buffer, pH 7.0, respectively. The diet plates were allowed to air-dry in a sterile flow-hood and the wells were infested with single, neonate Diabrotica undecimpunctata howardi (Southern corn rootworm, SCR) hatched from sterilized eggs, with second nstar SCR grown on artificial diet or with second instar Diabrotica virgif ra virgifera (Western corn rootworm, WCR) reared on corn seedlings grown in Metromix . Second instar larvae were weighed prior to addition to the diet. The plates were sealed, placed in a humidified growth chamber and maintained at 27°C for the appropriate period (4 days for neonate and adult SCR, 2-5 days for WCR larvae, 7-14 days for second instar SCR) . Mortality and weight determinations were scored as indicated Generally, 16 insects per treatment were used m all studies. Control mortalities were as follows: neonate larvae, <5%, adult beetles, 5%. Activity against Colorado potato beetle was tested as follows Photorhabdus culture broth or control medium was applied to the surface (about 2.0 cm * ) of 1.5 ml of standard artificial diet held in the wells of a 24-well tissue culture plate Each well received -30- SUBSTΓΓUTE SHEET (RULE 26) 50 μl of treatment and was allowed to air dry. Individual second instar Colorado potato beetle [Leptmotarsa decemlinea ta , CPB) larvae were then placed onto the diet and mortality was scored after 4 days Ten larvae per treatment were used in all studies. Control mortality was 3.3%. Activity against Japanese beetle grubs and beetles was tested as follows. Turf grubs [ Popillia japonica , 2-3rd instar) were collected from infested lawns and maintained in the laboratory in soil/peat mixture with carrot slices added as additional diet. Turf beetles were pheromone-trapped locally and maintained m the laboratory in plastic containers with maple leaves as food Following application of undiluted Photorhabdus culture broth or control medium to corn rootworm artificial diet (30 μl/1.54 cm 2 , beetles) or carrot slices (larvae), both stages were placed singly m a diet well and observed for any mortality and feeding In both cases there was a clear reduction in the amount of feeding (and feces production) observed. Activity against mosquito larvae was tested as follows. The assay was conducted in a 96-well microtiter plate Each well contained 200 μl of aqueous solution [ Photorhabdus culture broth, control medium or H 2 0) and approximately 20, 1-day old larvae [Aedes aegypti ) There were 6 wells per treatment. The results were read at 2 hours after infestation and did not change over the three day observation period. No control mortality was seen. Activity against fruitflies was tested as follows. Purchased Drosophila elanogaster medium was prepared using 50% dry medium and a 50% liquid of either water, control medium or Photorhabdus culture broth. This was accomplished by placing 8.0 ml of dry medium in each of 3 rearing vials per treatment and adding 8 0 ml of the appropriate liquid. Ten late instar Drosophila melanogaster maggots were then added to each vial. The vials were held on a laboratory bench, at room temperature, under fluorescent ceiling lights. Pupal or adult counts were made after 3, 7 and 10 days of exposure. Incorporation of Photorhabdus culture broth into the diet media for fruitfly maggots caused a slight (17%) but significant reduction in day- 10 adult emergence as compared to water and control medium (3% reduction) Activity against aster leafhopper was tested as follows. The mgestion assay for aster leafhopper [Macrosteles severini ) is designed to allow mgestion of the active without other external contact The reservoir for the active/ "food" solution is made by making 2 holes in the center of the bottom portion of a 35 x 10 mm Petri dish. A 2 inch Parafilm " square is placed across the top of -31- SUBSTΓΠJTE SHEET (RULE 26) the dish and secured with an "O" ring. A 1 oz. plastic cup is then infested with approximately 7 leafhoppers and the reservoir is placed on top of the cup, Parafilm down. The test solution is then added to the reservoir through the holes. In tests using undiluted Photorhabdus culture broth, the broth and control medium were dialyzed against water to reduce control mortality Mortality is reported at day 2 where 26.5% control mortality was seen. In the tests using purified fractions (200 mg protem/ml) a final concentration of 5% sucrose was used in all treatments to improve survivability of the aster leafhoppers. The assay was held in an incubator at 28 °C, 70% RH with a 16/8 photoperiod. The assay was graded for mortality at 72 hours. Control mortality was 5.5%. Activity against Argentine ants was tested as follows A 1.5 ml aliquot of 100% Photorhabdus culture broth, control medium or water was pipetted into 2.0 ml clear glass vials. The vials were plugged with a piece of cotton dental wick that was moistened with the appropriate treatment. Each vial was placed into a separate 60x16mm Petri dish with 8 to 12 adult Argentine ants [ Lmepi thema humile) . There were three replicates per treatment Bioassay plates were held on a laboratory bench, at room temperature under fluorescent ceiling lights. Mortality readings were made after 5 days of exposure. Control mortality was 24% Activity against carpenter ant was tested as follows Black carpenter ant workers [ Camponotus pennsylvamcus) were collected from trees on DowElanco property in Indianapolis, IN. Tests with Photorhabdus culture broth were performed as follows. Each plastic bioassay container (7 1/8" x 3") held fifteen workers, a paper harborage and 10 ml of broth or control media m a plastic shot glass. A cotton wick delivered the treatment to the ants through a hole m the shot glass lid. All treatments contained 5% sucrose Bioassays were held in the dark at room temperature and graded at 19 days. Control mortality was 9%. Assays delivering purified fractions utilized artificial ant diet mixed with the treatment (purified fraction or control solution) at a rate of 0.2 ml treatment/2.0 g diet in a plastic test tube. The final protein concentration of the purified fraction was less than 10 μg/g diet Ten ants per treatment, a water source, harborage and the treated diet were placed in sealed plastic containers and maintained m the dark at 27 °C in a humidified incubator Mortality was scored at day 10. No control mortality was seen. Activity against various lepidopteran larvae was tested as follows Photorhabdus culture broth or purified fractions were -32- SUBSTΓΓUTE SHEET (RULE 26) applied directly to the surface (about 1.5 cm ) of 0.25 ml of standard artificial diet in 30 μl aliquots following dilution in control medium or 10 mM sodium phosphate buffer, pH 7.0, respectively. The diet plates were allowed to air-dry in a sterile flow-hood and the wells were infested with single, neonate larva. European corn borer [ Ostrinia nubilalis) and corn earworm [Helicoverpa zea) eggs were supplied from commercial sources and hatched m-house, whereas beet armyworm [Ξpodoptera exigua) , cabbage looper [ Trichoplusia ni ) , tobacco budworm [Heliothis virescens) , codling moth (Laspeyresia pomonella) and black cutworm [Agrotis ipsilon) larvae were supplied internally. Following infestation with larvae, the diet plates were sealed, placed a humidified growth chamber and maintained in the dark at 27 °C for the appropriate period. Mortality and weight determinations were scored at days 5-7 for Photorhabdus culture broth and days 4-7 for the purified fraction. Generally, 16 insects per treatment were used in all studies. Control mortality ranged from 4-12.5% for control medium and was less than 10% for phosphate buffer. -33- SUBSTΓΓUTE SHEET (RULE 26) Tabl e 4 Effect of Photorhabdus luminescens (Strain W-14) Culture Broth and Purified Toxin Fraction on Mortality and Growth Inhibition of Different Insect Orders/Species or . = mor a i y, grow inhibi ion, na = not applicable, nt not tested, a.f anti-feedant Exa p e 3, Insecticide Utility upon Soil Application Photorhabdus l uminescens (strain W-14) culture broth was shown to be active against corn rootworm when applied directly to soil or a soil -mix (Metromix" ' ) . Activity against neonate SCR and WCR -34- SUBSTΓΓUTE SHEET (RULE 26) Metromix ® was tested as follows (Table 5) . The test was run using corn seedlings (United Agriseeds brand CL614) that were germinated m the light on moist filter paper for 6 days. After roots were approximately 3-6 cm long, a single kernel/seedlmg was planted in a 591 ml clear plastic cup with 50 gm of dry MetromixX Twenty neonate SCR or WCR were then placed directly on the roots of the seedling and covered with Metromix". Upon infestation, the seedlings were then drenched with 50 ml total volume of a diluted broth solution. After drenching, the cups were sealed and left at room temperature in the light for 7 days. Afterwards, the seedlings were washed to remove all Metromix " and the roots were excised and weighed. Activity was rated as the percentage of corn root remaining relative to the control plants and as leaf damage induced by feeding. Leaf damage was scored visually and rated as either -, +, ++, or +++, with - representing no damage and +++ representing severe damage. Activity against neonate SCR in soil was tested as follows (Table 6) . The test was run using corn seedlings (United Agriseeds brand CL614) that were germinated in the light on moist filter paper for 6 days. After the roots were approximately 3-6 cm long, a single kernel/seedlmg was planted in a 591 ml clear plastic cup with 150 gm of soil from a field in Lebanon, IN planted the previous year with corn. This soil had not been previously treated with insecticides. Twenty neonate SCR were then placed directly on the roots of the seedling and covered with soil. After infestation, the seedlings were drenched with 50 ml total volume of a diluted broth solution. After drenching, the unsealed cups were incubated in a high relative humidity chamber (80%) at 78°F Afterwards, the seedlings were washed to remove all soil and the roots " //ere excised and weighed.

Approximately 50 gm of dry Metromix * was added to a 591 ml clear plastic cup The Metromix * was then drenched with 50 ml total volume of a 50% (v/v) diluted Photorhabdus broth solution. The dilution of crude broth was made with water, with 50% broth being prepared by adding 25 ml of crude broth to 25 ml of water for 50 ml total volume A 1% (w/v) solution of proteose peptone #3 (PP3), which is a 50% dilution of the normal media concentration, was used as a broth control After drenching, five second instar turf grubs were placed on the top of the moistened Metromix * .

The leaves were air dried and cut into equal sized strips approximately 2 x 2 inches. The leaves were rolled, secured with paper clips and placed in 1 oz plastic shot glasses with 0.25 inch of 2% agar on the bottom surface to provide moisture. Twelve neonate European corn borers were then placed onto the rolled leaf and the cup was sealed. After incubation for 5 days at 27°C in the dark, the samples were scored for feeding damage and recovered larvae . -37- SUBSTΪTUTE SHEET (RULE 26) Table 8 Effect of Photorhabdus luminescens (Strain W-14) Culture Broth on European Corn Borer Larvae Following Pre- Infestation Application to Excised Maize Leaves Treatment Leaf Damage Larvae Recovered Weight (mg) Water Extensive 55/120 0.42 mg Control Medium _ Extensive 40/120 0.50 mg Broth (1.0% v/v) Trace 3/120 0.15 mg Activity of the culture broth against neonate tobacco budworm (Heliothis virescens) was demonstrated using a leaf dip methodology. Fresh cotton leaves were excised from the plant and leaf disks were cut with an 18.5 mm cork-borer. The disks were individually emersed in control medium (PP3) or Photorhabdus luminescens (strain W-14) culture broth which had been concentrated approximately 10-fold using an Amicon (Beverly, MA) , Proflux M12 tangential filtration system with a 10 kDa filter. Excess liquid was removed and a straightened paper clip was placed through the center of the disk. The paper clip was then wedged into a plastic, 1.0 oz shot glass containing approximately 2.0 ml of 1% Agar . This served to suspend the leaf disk above the agar. Following drying of the leaf disk, a single neonate tobacco budworm larva was placed on the disk and the cup was capped. The cups were then sealed in a plastic bag and placed in a darkened, 27°C incubator for 5 days. At this time the remaining larvae and leaf material were weighed to establish a measure of leaf damage (Table 9) .

Part A Characterization of Toxm Peptide Components In a subsequent analysis, the toxm protein subunits of the bands isolated as in Example 1 were resolved on a 7% SDS -38- SUBSTTTUTE SHEET (RULE 26) polyacrylamide electrophoresis gel with a ratio of 30:0.8 (acrylamide : BIS-acrylamide) . This gel matrix facilitates better resolution of the larger proteins. The gel system used to estimate the Band 1 and Band 2 subunit molecular weights Example 1 was an 18% gel with a ratio of 38:0.18 (acrylamide :BIS-acrylamιde) , which allowed for a broader range of size separation, but less resolution of higher molecular weight components. In this analysis, 10, rather than 8, protein bands were resolved Table 10 reports the calculated molecular weights of the 10 resolved bands, and directly compares the molecular weights estimated under these conditions to those of the prior example. It is not surprising that additional bands were detected under the different separation conditions used in this example. Variations between the prior and new estimates of molecular weight are also to be expected given the differences analytical conditions In the analysis of this example, it is thought that the higher molecular weight estimates are more accurate than in Example 1, as a result of improved resolution However, these are estimates based on SDS PAGE analysis, which are typically not analytically precise and result in estimates of peptides and which may have been further altered due to post- and co-translational modifications Am o acid sequences were determined for the N- terminal portions of five of the 10 resolved peptides Table 10 + correlates the molecular weight of the proteins and the identified sequences. In SEQ ID NO.2, certain analyses suggest that the prol e at residue 5 may be an asparag e (asn) . In SEQ ID NO: 3, certain analyses suggest that the am o acid residues at positions 13 and 14 are both arg ine (arg) In SEQ ID NO: 4, certain analyses suggest that the ammo acid residue at position 6 may be either alanme (ala) or ser e (ser) . In SEQ ID NO: 5, certain analyses suggest that the ammo acid residue at position 3 may be aspartic acid (asp) . -39- SUBSTΓΓUTE SHEET (RULE 26) Table .10 ESTIMATE NEW ESTIMATE* SEP.

Part B Characterization of Toxm Peptide Components New N-terminal sequence, SEQ ID NO: 15, Ala Gin Asp Gly Asn Gin Asp Thr Phe Phe Ser Gly Asn Thr, was obtained by further N- terminal sequencing of peptides isolated from Native HPLC-purifled tox as described m Example 5, Part A, above. This peptide comes from the tcaA gene. The peptide labeled TcaA n , starts at position 254 and goes to position 491, where the TcaA xll peptide starts, SEQ ID NO: 4 The estimated size of the peptide based on the gene sequence Example 6 Characterization of Tox Peptide Components In yet another analysis, the toxm protein complex was re- lsolated from the Photorhabdus luminescens growth medium (after culture without Tween) by performing a 10% - 80% ammonium sulfate precipitation followed by an ion exchange chromatography step (Mono Q) and two molecular sizing chromatography steps. These conditions were like those used in Example 1 During the first molecular sizing step, a second biologically active peak was found at about 100 ± 10 kDa. Based upon protein measurements, this fraction was 20 - 50 fold less active than the larger, or primary, active peak of about 860 ± 100 kDa (native) . During this isolation experiment a smaller active peak of about 325 ± 50 kDa that retained a considerable portion of the starting biological activity was also resolved. It is thought that the 325 kDa peak is related to or derived from the 860 kDa peak. A 56 kDa protein was resolved in this analysis. The N- termmal sequence of this protein is presented in SEQ ID NO: 6 It is noteworthy that this protein shares significant identity and conservation with SEQ ID NO: 5 at the N-termihus, suggesting that the two may be encoded by separate members of a gene family and that the proteins produced by each gene are sufficiently similar to both be operable in the insecticidal toxin complex. A second, prominent 185 kDa protein was consistently present in amounts comparable to that of protein 3 from Table 10, and may be the same protein or protein fragment. The N-terminal sequence of this 185 kDa protein is shown at SEQ ID NO: 7. Additional N-terminal amino acid sequence data were also obtained from isolated proteins. None of the determined N-terminal sequences appear identical to a protein identified in Table 10. Other proteins were present in isolated preparation. One such protein has an estimated molecular weight of 108 kDa and an N- terminal sequence as shown in SEQ ID NO: 8. A second such protein has an estimated molecular weight of 80 kDa and an N-terminal sequence as shown in SEQ ID NO: 9. When the protein material in the approximately 325 kDa active peak was analyzed by size, bands of approximately 51, 31, 28, and 22 kDa were observed. As in all cases in which a molecular weight was determined by analysis of electrophoretic mobility, these molecular weights were subject to error effects introduced by buffer ionic strength differences, electrophoresis power differences, and the like. One of ordinary skill would understand that definitive molecular weight values cannot be determined using these standard methods and that each was subject to variation. It was hypothesized that proteins of these sizes are degradation products of the larger protein species (of approximately 200 kDa size) that were observed in the larger primary toxin complex. Finally, several preparations included a protein having the N- terminal sequence shown in SEQ ID NO: 10. This sequence was strongly homologous to known chaperonin proteins, accessory proteins known to function in the assembly of large protein complexes. Although the applicants could not ascribe such an assembly function to the protein identified in SEQ ID NO: 10, it was consistent with the existence of the described toxin protein complex that such a chaperonin protein could be involved in its assembly. Moreover, although such proteins have not directly been suggested to have toxic activity, this protein may be important to determining the overall structural nature of the protein toxin, and thus, may contribute to the toxic activity or durability of the complex in vivo after oral delivery. -41- SUBSTΓΓUTE SHEET (RULE 25) Subsequent analysis of the stability of the protein tox complex to protemase K was undertaken It was determined that after 24 hour incubation of the complex in the presence of a 10- fold molar excess of protemase K, activity was virtually eliminated (mortality on oral application dropped to about 5%) . These data confirm the prote aceous nature of the tox The toxic activity was also retained by a dialysis membrane, again confirming the large size of the native tox complex Example 7 Isolation. Characterization and Partial Ammo Acid Sequencing of Photorhabdus Toxms Isolation and N-Termmal Ammo Acid Sequencing In a set of experiments conducted in parallel to Examples 5 and 6, ammonium sulfate precipitation of Photorhabdus proteins was performed by adjusting Photorhabdus broth, typically 2-3 liters, to a final concentration of either 10% or 20% by the slow addition of ammonium sulfate crystals. After stirring for 1 hour at 4°C, the material was centrifuged at 12,000 x g for 30 minutes. The supernatant was ad}usted to 80% ammonium sulfate, stirred at 4°C for 1 hour, and centrifuged at 12,000 x g for 60 minutes The pellet was resuspended in one-tenth the volume of 10 mM Na 2 P0 4 , pH 7.0 and dialyzed against the same phosphate buffer overnight at 4°C. The dialyzed material was centrifuged at 12,000 x g for 1 hour prior to ion exchange chromatography A HR 16/50 Q Sepharose (Pharmacia) anion exchange column was equilibrated with 10 mM Na 2 P0 4 , pH 7 0. Centrifuged, dialyzed ammonium sulfate pellet was applied to the Q Sepharose column at a rate of 1.5 ml/mm and washed extensively at 3.0 ml/mm with equilibration buffer until the optical density (O.D. 280) reached less than 0.100. Next, either a 60 minute NaCl gradient ranging from 0 to 0.5 M at 3 ml/mm, or a series of step elutions using 0.1 M, 0.4 M and finally 1.0 NaCl for 60 minutes each was applied to the column. Fractions were pooled and concentrated using a Centriprep 100 Alternatively, proteins could be eluted by a single 0.4 M NaCl wash without prior elution with 0.1 M NaCl. Two illiliter aliquots of concentrated Q Sepharose samples were loaded at 0.5 ml/mm onto a HR 16/50 Superose 12 (Pharmacia) gel filtration column equilibrated with 10 mM Na 2 P0 4 , pH 7 0 The column was washed with the same buffer for 240 mm at 0 5 ml/min and 2 mm samples were collected The void volume material was -42- SUBSTΪTUTE SHEET (RULE 26) collected and concentrated using a Centriprep 100. Two milliliter aliquots of concentrated Superose 12 samples were loaded at 0.5 ml/min onto a HR 16/50 Sepharose 4B-CL (Pharmacia) gel filtration column equilibrated with 10 mM Na 2 ' P0 4 , pH 7.0. The column was washed with the same buffer for 240 min at 0.5 ml/min and 2 min samples were collected. The excluded protein peak was subjected to a second fractionation by application to a gel filtration column that used a Sepharose CL-4B resin, which separates proteins ranging from about 30 kDa to 1000 kDa. This fraction was resolved into two peaks,- a minor peak at the void volume (>1000 kDa) and a major peak which eluted at an apparent molecular weight of about 860 kDa. Over a one week period subsequent samples subjected to gel filtration showed the gradual appearance of a third peak (approximately 325 kDa) that seemed to arise from the major peak, perhaps by limited proteolysis. Bioassays performed on the three peaks showed that the void peak had no activity, while the 860 kDa toxin complex fraction was highly active, and the 325 kDa peak was less active, although quite potent. SDS PAGE analysis of Sepharose CL-4B toxin complex peaks from different fermentation productions revealed two distinct peptide patterns, denoted "P" and "S". The two patterns had marked differences in the molecular weights and concentrations of peptide components in their fractions. The "S" pattern, produced most frequently, had 4 high molecular weight peptides (> 150 kDa) while the "P" pattern had 3 high molecular weight peptides. In addition, the "S" peptide fraction was found to have 2-3 fold more activity against European Corn Borer. This shift may be related to variations in protein expression due to age of inoculum and/or other factors based on growth parameters of aged cultures. Milligram quantities of peak toxin complex fractions determined to be "P" or "S" peptide patterns were subjected to preparative SDS PAGE, and transblotted with TRIS-glycine (Seprabuff™ to PVDF membranes (ProBlott™, Applied Biosystems) for 3-4 hours. Blots were sent for amino acid analysis and N-terminal amino acid sequencing at Harvard MicroChem and Cambridge ProChem, respectively. Three peptides in the "S" pattern had unique N- terminal amino acid sequences compared to the sequences identified in the previous example. A 201 kDa (TcdAϋ) peptide set forth as SEQ ID NO: 13 below shared between 33% amino acid identity and 50% similarity (similarity and identity were calculated by hand) with SEQ ID NO:l (TcbAϋ) (in Table 10 vertical lines denote ammo acid -43- SUBSTΓΓUTE SHEET (RULE 26) identities and colons indicate conservative amino acid substitutions) . A second peptide of 197 kDa, SEQ ID NO:14 (TcdB), had 42% identity and 58% similarity with SEQ ID NO: 2 (TcaC) (similarity and identity were calculated by hand) . Yet a third peptide of 205 kDa was denoted TcdA ι:L . In addition, a limited N- terminal ammo acid sequence, SEQ ID NO:16 (TcbA), of a peptide of at least 235 kDa was identical with the ammo acid sequence, SEQ ID NO:12, deduced from a cloned gene [ tcbA) , SEQ ID NO:ll, containing a deduced ammo acid sequence corresponding to SEQ ID NO:l (TcbA i) . This indicates that the larger 235+ kDa peptide was proteolytically processed to the 201 kDa peptide, (TcbAn), (SEQ ID NO.-l) during fermentation, possibly resulting in activation of the molecule. In yet another sequence, the sequence originally reported as SEQ ID NO: 5 (TcaB ι;L ) reported in Example 5 above, was found to contain an aspartic acid residue (Asp) at the third position rather than glycme (Gly) and two additional ammo acids Gly and Asp at the eighth and ninth positions, respectively. In yet two other sequences, SEQ ID NO: 2 (TcaC) and SEQ ID NO: 3 (TcaB 1 ), additional ammo acid sequence was obtained. Densitometric quantitation was performed using a sample that was identical to the "S" preparation sent for N-termmal analysis. This analysis showed that the 201 kDa and 197 kDa peptides represent 7.0% and 7.2%, respectively, of the total Coomassie brillant blue stained protein the "S" pattern and are present in amounts similar to the other abundant peptides. It was speculated that these peptides may represent protein homologs, analogous to the situation found with other bacterial toxms, such as various Cryl Bt toxms. These proteins vary from 40-90% similarity at their N-termmal ammo acid sequence, which encompasses the toxic fragment. Internal Ammo Acid Sequencing To facilitate cloning of toxm peptide genes, internal ammo acid sequences of selected peptides were obtained as followed. Milligram quantities of peak 2A fractions determined to be "P" or "S" peptide patterns were subjected to preparative SDS PAGE, and transblotted with TRIS-glycme (Seprabuff™ to PVDF membranes (ProBlott™, Applied Biosystems) for 3-4 hours. Blots were sent for ammo acid analysis and N-termmal ammo acid sequencing at Harvard MicroChem and Cambridge ProChem, respectively. Three peptides, referred to as TcbA l (containing SEQ ID NO:l), TcdA 11( and TcaB x (containing SEQ ID NO: 3) were SUDJ ected to trypsm digestion by -44- SUBSTΓΠJTE SHEET (RULE 26) Harvard MicroChem followed by HPLC chromatography to separate individual peptides N-termmal ammo acid analysis was performed on selected tryptic peptide fragments . Two internal peptides were sequenced for the peptide TcdA lx (205 kDa peptide) referred to as TcdAn-PTlll (SEQ ID NO:17) and TcdA ι;L -PT79 (SEQ ID NO:18). Two internal peptides were sequenced for the peptide TcaBx (68 kDa peptide) referred to as TcaBi-PTlδθ (SEQ ID NO: 19) and TcaBi-PTlOδ (SEQ ID NO: 20) . Four internal peptides were sequenced for the peptide TcbA lx (201 kDa peptide) referred to as TcbA 11 -PT103 (SEQ ID N0:21), TcbA ι:L -PT56 (SEQ ID NO:22), TcbA ι;L -PT81 (a) (SEQ ID NO: 23), and TcbAn-PT81 (b) (SEQ ID NO: 24).

This objective was pursued m parallel One approach, described later, was based on the use of monoclonal and polyclonal antibodies raised against the purified toxm which were then used to isolate clones from an expression library The other approach, described in this example, is based on the use of the N-terminal and internal ammo acid sequence data to design degenerate oligonucleotides for use in PCR amplication Either method can be used to identify DNA clones that contain the peptide-encoding genes so as to permit the isolation of the respective genes, and the determination of their DNA base sequence -4b- SUBSTΓΓUTE SHEET (RULE 26) Genomic DNA Isolation Photorhabdus luminescens strain W-14 (ATCC accession number 55397) was grown on 2% proteose peptone #3 agar (Difco Laboratories, Detroit, MI) and msecticidal tox competence was maintained by repeated bioassay after passage, using the method described in Example 1 above. A 50 ml shake culture was produced in a 175 ml baffled flask in 2% proteose peptone #3 medium, grown at 28°C and 150 rpm for approximately 24 hours. 15 ml of this culture was pelleted and frozen in its medium at -20°C until it was thawed for DNA isolation. The thawed culture was centrifuged, (700 x g, 30 mm) and the floating orange mucopolysaccharide material was removed. The remaining cell material was centrifuged (25,000 x g, 15 mm) to pellet the bacterial cells, and the medium was removed and discarded. Genomic DNA was isolated by an adaptation of the CTAB method described in section 2.4.1 of Current Protocols m Molecular Biology (Ausubel et al . eds, John Wiley & Sons, 1994) [modified to include a salt shock and with all volumes increased 10 -fold] The pelleted bacterial cells were resuspended m TE buffer (10 mM Tπs- HCl, 1 mM EDTA, pH 8.0) to a final volume of 10 ml, then 12 ml of 5 M NaCl was added; this mixture was centrifuged 20 mm at 15,000 x g. The pellet was resuspended in 5.7 ml TE and 300 ml of 10% SDS and 60 ml of 20 mg/ l protemase K (Gibco BRL Products, Grand Island, NY; sterile distilled water) were added to the suspension. This mixture was incubated at 37°C for 1 hr, then approximately 10 mg lysozyme (Worthmgton Biochemical Corp., Freehold, NJ) was added. After an additional 45 mm, 1 ml of 5 M NaCl and 800 ml of CTAB/NaCl solution (10% w/v CTAB, 0 7 M NaCl) were added. This preparation was incubated 10 mm at 65°C, then gently agitated and further incubated and agitated for approximately 20 mm to assist clearing of the cellular material. An equal volume of chloroform/isoamyl alcohol solution (24.1, v/v) was added, mixed gently and centrifuged. After two extractions with an equal volume of PCI (phenol/chloroform/isoamyl alcohol; 50:49:1, v/v/v; equilibrated with 1 M Tris-HCl, pH 8.0; Intermountam Scientific Corporation, Kaysville, UT) , the DNA was precipitated with 0.6 volume of isopropanol. The DNA precipitate was gently removed with a glass rod, washed twice with 70% ethanol, dried, and dissolved in 2 ml STE (10 mM Tris-HCl pH 8.0 , 10 mM NaCl, 1 mM EDTA) . This preparation contained 2 5 mg/ml DNA, as determined by optical density at 260 nm (i.e., OD 260 ) . The molecular size range of the isolated genomic DNA was evaluated for suitability for library construction. CHEF gel analysis was performed in 1.5% agarose (Seakem ^ LE, FMC BioProducts, Rockland, ME) gels with 0.5 X TBE buffer (44.5 mM Tris-HCl pH 8.0, 44.5 mM H 3 B0 3 , 1 mM EDTA) on a BioRad CHEF-DR II apparatus with a Pulsewave 760 Switcher (Bio-Rad Laboratories, Inc., Richmond, CA) . The running parameters were: initial A time, 3 sec,- final A time, 12 sec; 200 volts; running temperature, 4-18°C; run time, 16.5 hr . Ethidium bromide staining and examination of the gel under ultraviolet light indicated the DNA ranged from 30-250 kbp in size. Construction of Library A partial Sau3A 1 digest was made of this Photorhabdus genomic DNA preparation. The method was based on section 3 1.3 of Ausubel (supra.) Adaptions mcluded running smaller scale reactions under various conditions until nearly optimal results were achieved. Several scaled-up large reactions with varied conditions were run, the results analyzed on CHEF gels, and only the best large scale preparation was carried forward. In the optimal case, 200 μg of Photorhabdus genomic DNA was incubated with 1.5 units of Sau3A 1 (New England Biolabs, "NEB", Beverly, MA) for 15 mm at 37°C in 2 ml total volume of IX NEB 4 buffer (supplied as 10X by the manufacturer) The reaction was stopped by adding 2 ml of PCI and centrifugmg at 8000 x g for 10 mm. To the supernatant were added 200 μl of 5 M NaCl plus 6 ml of ice-cold ethanol. This preparation was chilled for 30 mm at -20°C, then centrifuged at 12,000 x g for 15 mm. The supernatant was removed and the precipitate was dried in a vacuum oven at 40°C, then resuspended m 400 μl STE . Spectrophotometπc assay indicated about 40% recovery of the input DNA. The digested DNA was size fractionated on a_ sucrose gradient according to section 5.3.2 of CPMB [ op . ci t . ) . A 10% to 40% (w/v) linear sucrose gradient was prepared with a gradient maker m Ultra-Clear™ tubes (Beckman Instruments, Inc., Palo Alto, CA) and the DNA sample was layered on top. After centrifugation, (26,000 rpm, 17 hr, Beckman SW41 rotor, 20°C) , fractions (about 750 μl) were drawn from the top of the gradient and analyzed by CHEF gel electrophoresis (as described earlier) . Fractions containing Sau3A 1 fragments in the size range 20-40 kbp were selected and DNA was precipitated by a modification (amounts of all solutions increased approximately 6.3 -fold) of the method in section 5.3.3 of Ausubel [ supra . ) After overnight precipitation, the DNA was collected by centrifugation (17,000 x g, 15 mm), dried, redissolved in TE, pooled into a final volume of 80 μl , and reprecipitated with the addition of 8 μl 3 M sodium acetate and 220 μl ethanol. The pellet collected by centrifugation as above was resuspended in 12 μl TE. Concentration of the DNA was determined by Hoechst 33258 dye (Polysciences, Inc., Warrmgton, PA) fluorometry a Hoefer TKO100 fluoπmeter (Hoefer Scientific Instruments, San Francisco, CA) . Approximately 2.5 μg of the size-fractionated DNA was recovered. Thirty μg of cosmid pWE15 DNA (Stratagene, La Jolla, CA) was digested to completion with 100 units of restriction enzyme BamH 1 (NEB) in the manufacturer's buffer (final volume of 200 μl, 37°C, 1 hr) . The reaction was extracted with 100 μl of PCI and DNA was precipitated from the aqueous phase by addition of 20 μl 3M sodium acetate and 550 μl -20°C absolute ethanol. After 20 mm at -70°C, the DNA was collected by centrifugation (17,000 x g, 15 mm), dried under vacuum, and dissolved m 180 μl of 10 mM Tris-HCl, pH 8.0. To this were added 20 μl of 10X CIP buffer (100 mM Tris-HCl, pH 8.3, 10 mM ZnCl 2 ; 10 mM MgCl 2 ) , and 1 μl (0.25 units) of 1 4 diluted calf intestinal alkaline phosphatase (Boehringer Mannheim Corporation, Indianapolis, IN) . After 30 mm at 37°C, the following additions were made. 2 μl 0.5 M EDTA, pH 8.0 , 10 μl 10% SDS, 0.5 μl of 20 mg/ml prote ase K (as above), followed by incubation at 55°C for 30 mm. Following sequential extractions with 100 μl of PCI and 100 μl phenol (Intermountam Scientific Corporation, equilibrated with 1 M Tris-HCl, pH 8.0), the dephosphorylated DNA was precipitated by addition of 72 μl of 7.5 M ammonium acetate and 550 μl -20°C ethanol, incubation on ice for 30 mm, and centrifugation as above. The pelleted DNA was washed once with 500 μl -20°C 70% ethanol, dried under vacuum, and dissolved 20 μl of TE buffer. Ligation of the size-fractionated Sau3A 1 fragments to the BamH 1 -digested and phosphatased pWE15 vector was accomplished using T4 ligase (NEB) by a modification (i.e., use of premixed 10X ligation buffer supplied by the manufacturer) of the protocol section 3.33 of Ausubel. Ligation was carried out overnight m a total volume of 20 μl at 15°C, followed by storage at - 20°C. Four μl of the cosmid DNA ligation reaction, containing about 1 μg of DNA, was packaged into bacteriophage lambda using a commercial packaging extract (Gigapack * III Gold Packaging Extract, Stratagene), following the manufacturer's directions. The packaged preparation was stored at 4°C until use The packaged cosmid preparation was used to infect Escheπ chia coli XLI Blue MR cells 48- SUBSTΓΓUTE SHEET (RULE 26) (Stratagene) according to the Gιgapa,ck" III Gold protocols ("Titermg the Cosmid Library"), as follows. XLI Blue MR cells were grown in LB medium (g/L: Bacto-tryptone , 10; Bacto-yeast extract, 5; Bacto-agar, 15; NaCl, 5; [Difco Laboratories, Detroit, MI]) containing 0.2% (w/v) maltose plus 10 mM MgS0 4 , at 37°C. After 5 hr growth, cells were pelleted at 700 x g (15 min) and resuspended m 6 ml of 10 mM MgSO, . The culture density was ad j usted with 10 mM MgSO, to OD 600 = 0.5 The packaged cosmid library was diluted 1:10 or 1.20 with sterile SM medium (0 1 M NaCl, 10 mM MgSO, 50 mM Tris-HCl pH 7.5, 0.01% w/v gelatin), and 25 μl of the diluted preparation was mixed with 25 μl of the diluted XLI Blue MR cells. The mixture was incubated at 25°C for 30 mm (without shaking) , then 200 μl of LB broth was added, and incubation was continued for approximately 1 hr with occasional gentle shaking. Aliquots (20-40 μl) of this culture were spread on LB agar plates containing 100 mg/1 ampicillm d e., LB-Amp ^00 ) and incubated overnight at 37 °C. To store the library without amplification, single colonies were picked and inoculated into individual wells of sterile 96-well microwell plates; each well containing 75 μl of Terrific Broth (TB media. 12 g/1 Bacto- tryptone, 24 g/1 Bacto-yeast extract, 0.4% v/v glycerol, 17 mM KH 2 P0 4 , 72 mM K 2 HP0 plus 100 mg/1 ampicillm (i.e , TB-Amp 100 ) and incubated (without shaking) overnight at 37°C. After replicating the 96-well plate into a copy plate, 75 μl/well of filter- sterilized TB:glycerol (1:1, v/v; with, or without, 100 mg/1 ampicillm) was added to the plate, it was shaken briefly at 100 rpm, 37°C, and then closed with ParafilirT (American National Can, Greenwich, CT) and placed in a -70°C freezer for storage. Copy plates were grown and processed identically to the master plates. A total of 40 such master plates (and their copies) were prepared. Screening of the Library with Radiolabeled DNA Probes To prepare colony filters for probing with radioactively labeled probes, ten 96-well plates of the library were thawed at 25°C (bench top at room temperature) A replica plating tool with 96 prongs was used to inoculate a fresh 96-well copy plate containing 75 μl/well of TB-Amp 100 . The copy plate was grown overnight (stationary) at 37°C, then shaken about 30 mm at 100 rpm at 37°C. A total of 800 colonies was represented m these copy plates, due to nongrowth of some isolates. The replica tool was used to inoculate duplicate impressions of the 96-well arrays onto Magna NT (MSI, Westboro, MA) nylon membranes (0.45 micron, 220 x -49- SUBSTΓΓUTE SHEET (RULE 26) 250 mm) which had been placed on solid LB-Amp 100 (100 ml/dish) in Bio-assay plastic dishes (Nunc, 243 x 243 x 18 mm; Curtm Mathison Scientific, Inc., Wood Dale, IL) . The colonies were grown on the membranes at 37°C for about 3 hr . A positive control colony (a bacterial clone containing a GZ4 sequence insert, see below) was grown on a separate Magna NT membrane (Nunc, 0.45 micron, 82 mm circle) on LB medium supplemented with 35 mg/1 chloramphenicol (i.e., LB-Cam 35 ) , and processed alongside the library colony membranes. Bacterial colonies on the membranes were lysed, and the DNA was denatured and neutralized according to a protocol taken from the Genius™ System User's Guide version 2.0 (Boehr ger Mannheim, Indianapolis, IN) Membranes were placed colony side up on filter paper soaked with 0.5 N NaOH plus 1.5 M NaCl for 15 mm to denature, and neutralized on filter paper soaked with 1 M Tris-HCl pH 8.0 , 1.5 M NaCl for 15 mm After UV-crosslinkmg using a Stratagene UV Stratalinker set on auto crosslink, the membranes were stored dry at 25°C until use Membranes were trimmed into strips containing the duplicate impressions of a single 96-well plate, then washed extensively by the method of section 6.4.1 in CPMB [ op. ci t . ) 3 hr at 25°C in 3X SSC, 0.1% (w/v) SDS, followed by 1 hr at 65°C in the same solution, then rinsed in 2X SSC in preparation for the hybridization step (20X SSC = 3 M NaCl, 0.3 M sodium citrate, pH 7.0) Amplification of a Specific Genomic Fragment of a TcaC Gene Based on the N-termmal ammo acid sequence determined for the purified TcaC peptide fraction [disclosed herein as SEQ ID N0:2], a pool of degenerate oligonucleotides (pool S4Psh) was synthesized by standard β-cyanoethyl chemistry on an Applied BioSystem ABI394 DNA7RNA Synthesizer (Perkm Elmer, Foster City, CA) . The oligonucleotides were deprotected 8 hours at 55°C\ "" dissolved in water, quantitated by spectrophotometric measurement, and diluted for use. This pool corresponds to the determined N-termmal ammo acid sequence of the TcaC peptide. The determined am o acid sequence and the corresponding degenerate DNA sequence are given below, where A, C, G, and T are the standard DNA bases, and I represents mosme: Amino Met Gin Asp Ser Pro Glu Val S4Psh 5' ATG CA(A/G) GA(T/C) (T/A) (C/G) (T/A) CCI GA(A/G) GT 3' Another set of degenerate oligonucleotides was synthesized (pool P2.3.5R), representing the complement of the coding strand for the determined ammo acid sequence of the SEQ ID NO: 17 -50- SUBSTΠΓUTE SHEET (RULE 26) Ammo Acid Ala Phe Asn lie Asp Asp Val Codons 5' GCN TT(T/C) AA(T/C) AT (A/T/C) GA(T/C) GA(T/C) GT 3' P2 3.5R 3'CG(A/C/G/T) AA(A/G) TT(A/G) TA(T/A/G) CT (A/G) CT(A/G) CA 5' These oligonucleotides were used as primers in Polymerase Cham Reactions (PCR S , Roche Molecular Systems, Branchburg, NJ) to amplify a specific DNA fragment from genomic DNA prepared from Photorhabdus strain W-14 (see above) . A typical reaction (50 μl) contained 125 pmol of each primer pool P2Psh and P2.3.5R, 253 ng of genomic template DNA, 10 nmol each of dATP, dCTP, dGTP, and dTTP, IX GeneAmp"' PCR buffer, and 2.5 units of AmpliTaq " DNA polymerase (both from Roche Molecular Systems,- 10X GeneAmp ® buffer is 100 mM Tris-HCl pH 8.3, 500 mM KC1 , 0.01% w/v gelatin). Amplifications were performed in a Perkm Elmer Cetus DNA Thermal Cycler (Perkin Elmer, Foster City, CA) using 35 cycles of 94°C (1.0 mm), 55°C (2.0 mm), 72°C (3.0 mm), followed by an extension period of 7.0 mm at 72 °C Amplification products were analyzed by electrophoresis through 2% w/v NuSieve" 3:1 agarose (FMC BioProducts) m TEA buffer (40 mM Tris-acetate, 2 mM EDTA, pH 8.0) . A specific product of estimated size 250 bp was observed amongst numerous other amplification products by ethidium bromide (0.5 μg/ l) staining of the gel and examination under ultraviolet light. The region of the gel containing an approximately 250 bp product was excised, and a small plug (0.5 mm dia.) was removed and used to supply template for PCR amplification (40 cycles) The reaction (50 μl) contained the same components as above, minus genomic template DNA. Following amplification, the ends of the fragments were made blunt and were phosphorylated by incubation at 25°C for 20 mm with 1 unit of T4 DNA polymerase (NEB) , 1 nmol ATP, and 2.15 units of T4 kinase (Pharmacia Biotech Inc., Piscataway, NJ) . DNA fragments were separated from residual primers by electrophoresis through 1% w/v GTG" agarose (FMC) in TEA. A gel slice containing fragments of apparent size 250 bp was excised, and the DNA was extracted using a Qiaex kit (Qiagen Inc., Chatsworth, CA) . The extracted DNA fragments were ligated to plasmid vector pBC KS(+) (Stratagene) that had been digested to completion with restriction enzyme Sma 1 and extracted in a manner similar to that descπned for pWE15 DNA above. A typical ligation reaction (16.3 μl) contained 100 ng of digested pBC KS(+) DNA, 70 ng of 250 bp fragment DNA, 1 nmol [Co (NH 3 ) J Cl 3 , and 3.9 Weiss units of T4 DNA ligase (Collaborative Biomedical Products, Bedford, MA), IX -51- SUBSTITUTE SHEET (RULE 25) ligation buffer (50 mM Tris-HCl, pH.7.4; 10 mM MgCl : ; 10 mM dithiothreitol; 1 mM spermidine, 1 mM ATP, 100 mg/ml bovine serum albumin) . Following overnight incubation at 14 °C, the ligated products were transformed into frozen, competent Escherichia coli DH5α cells (Gibco BRL) according to the suppliers' recommendations, and plated on LB-Cam 35 plates , containing IPTG (119 μg/ l) and X-gal (50 μg/ml) . Independent white colonies were picked, and plasmid DNA was prepared by a modified alkaline-lysis/PEG precipitation method (PRISM™ Ready Reaction DyeDeoxy™ Terminator Cycle Sequencing Kit Protocols; ABI/Perkin Elmer). The nucleotide sequence of both strands of the insert DNA was determined, using T7 primers [pBC KS(+) bases 601-623: TAAAACGACGGCCAGTGAGCGCG) and LacZ primers [pBC KS(+) bases 792-816: ATGACCATGATTACGCCAAGCGCGC) and protocols supplied with the PRISM™ sequencing kit (ABI/Perkin Elmer) . Nonincorporated dye-terminator dideoxyribonucleotides were removed by passage through Centri-Sep 100 columns (Princeton Separations, Inc., Adelphia, NJ) according to the manufacturer's instructions. The DNA sequence was obtained by analysis of the samples on an ABI Model 373A DNA Sequencer (ABI/Perkin Elmer) . The DNA sequences of two isolates, GZ4 and HB14, were found to be as illustrated in Fig. 1. This sequence illustrates the following features: 1) bases 1- 20 represent one of the 64 possible sequences of the S4Psh degenerate oligonucleotides, ii) the sequence of amino acids 1-3 and 6-12 correspond exactly to that determined for the N-terminus of TcaC (disclosed as SEQ ID NO: 2), iii) the fourth amino acid encoded is a cysteine residue rather than serine. This difference is encoded within the degeneracy for the serine codons (see above) , iv) the fifth amino acid encoded is proline, corresponding to the TcaC N-terminal sequence given as SEQ ID NO:2, v) bases 257-276 encode one of the 192 possible sequences designed into the degenerate pool, vi ) the TGA termination codon introduced at bases 268-270 is the result of complementarity to the degeneracy built into the oligonucleotide pool at the corresponding position, and does not indicate a shortened reading frame for the corresponding gene . Labeling of a TcaC Peptide Gene-speci ic Probe DNA fragments corresponding to the above 276 bases were amplified (35 cycles) by PCR S in a 100 μl reaction volume, using 100 pmol each of P2Psh and P2.3.5R primers, 10 ng of plasmids GZ4 or HB14 as templates, 20 nmol each of dATP, dCTP, dGTP, and dTTP, 5 -52- SUBSTΓΓUTE SHEET (RULE 26) units of AmpliTAq * DNA polymerase, and IX concentration of GeneAmp" buffer, under the same temperature regimes as described above. The amplification products were extracted from a 1% GTG " agarose gel by Qiaex kit and quantitated by fluorometry The extracted amplification products from plasmid HB14 template (approximately 400 ng) were split into five aliquots and labeled with "P-dCTP using the High Prime Labeling Mix (Boehringer Mannheim) according to the manufacturer's instructions. Nonmcorporated radioisotope was removed by passage through NucTrap * Probe Purification Columns (Stratagene) , according to the supplier's instructions. The specific activity of the labeled DNA product was determined by scintillation counting to be 3.11 x 10 β dpm/μg This labeled DNA was used to probe membranes prepared from 800 members of the genomic library. Screening with a TcaC-peptide Gene Specific Probe The radiolabeled HB14 probe was boiled approximately 10 mm, then added to "minimal hyb" solution. [Note: The "minimal hyb" method is taken from a CERES protocol, "Restriction Fragment Length Polymorphism Laboratory Manual version 4.0", sections 4-40 and 4- 47; CERES/NPI, Salt Lake City, UT. NPI is now defunct, with its successors operating as Linkage Genetics] . "Minimal hyb" solution contains 10% w/v PEG (polyethylene glycol, M.W. approx. 8000), 7% w/v SDS; 0.6X SSC, 10 mM sodium phosphate buffer (from a 1M stock containing 95 g/1 NaH 2 P0 4 1H 2 0 and 84.5 g/1 Na 2 HPO„ 7H 2 0) , 5 mM EDTA, and 100 mg/ml denatured salmon sperm DNA. Membranes were blotted dry briefly then, without prehybπdization, 5 strips of membrane were placed in each of 2 plastic boxes containing 75 ml of "minimal hyb" and 2.6 ng/ml of radiolabeled HB14 probe. These were incubated overnight with slow shaking (50 rpm) at 60 °C. The filters were washed three times for approximately 10 mm each at 25°C m "minimal hyb wash solution" (0.25X SSC, 0.2% SDS), followed by two 30-mm washes with slow shaking at 60°C in the same solution. The filters were placed on paper covered with Saran Wrap ' (Dow Brands, Indianapolis, IN) in a light-tight autoradiographic cassette and exposed to X-Omat X-ray film (Kodak, Rochester, NY) with two DuPont Cronex Lightnmg-Plus Cl enhancers (Sigma Chemical Co., St. Louis, MO), for 4 hr at -70°C. Upon development (standard photographic procedures) , significant signals were evident in both replicates amongst a high background of weaker, more irregular signals The filters were again washed for about 4 hr at 68 °C in "minimal hyb wash solution" and then placed again in the cassettes and film was exposed overnight at -7D°C. Twelve possible positives were identified due to strong signals on both of the duplicate 96- well colony impressions No signal was seen with negative control membranes (colonies of XLI Blue MR cells containing pWE15) , and a very strong signal was seen with positive control membranes (DH5α cells containing the GZ4 isolate of the PCR product) that had been processed concurrently with the experimental samples. The twelve putative hybridization-positive colonies were retrieved from the frozen 96-well library plates and grown overnight at 37°C on solid LB-Amp 100 medium They were then patched (3/plate, plus three negative controls: XLI Blue MR cells containing the pWE15 vector) onto solid LB-Amp 100 Two sets of membranes (Magna NT nylon, 0.45 micron) were prepared for hybridization. The first set was prepared by placing a filter directly onto the colonies on a patch plate, then removing it with adherent bacterial cells, and processing as below Filters of the second set were placed on plates containing LB-Amp 100 medium, then inoculated by transferring cells from the patch plates onto the filters. After overnight growth at 37°C, the filters were removed from the plates and processed. Bacterial cells on the filters were lysed and DNA denatured by placing each filter colony-side-up on a pool (1.0 ml) of 0 5 N NaOH in a plastic plate for 3 mm. The filters were blotted dry on a paper towel, then the process was repeated with fresh 0 5 N NaOH. After blotting dry, the filters were neutralized by placing each on a 1.0 ml pool of 1 M Tris-HCl, pH 7.5 for 3 min, blotted dry, and reneutralised with fresh buffer. This was followed by two similar soak gs (5 mm each) on pools of 0 5 M Tris-HCl pH 7 5 plus 1.5 M NaCl. After blotting dry, the DNA was UV crosslinked to the filter (as above) , and the filters were washed (25°C, 100 rpm) in about 100 ml of 3X SSC plus 0.1% (w/v) SDS (4 times, 30 mm each with fresh solution for each wash) They were then placed in a minimal volume of prehybridization solution [6X SSC plus 1% w/v each of Ficoll 400 (Pharmacia), polyvmylpyrrolidone (av. M.W. 360,000; Sigma ) and bovine serum albumin Fraction V, (Sigma) ] for 2 hr at 65°C, 50 rpm The prehybridization solution was removed, and replaced with the HB14 32 P-labeled probe that had been saved from the previous hybridization of the library membranes and which had been denatured at 95°C for 5 mm Hybridization was performed at 60 °C for 16 hr with shaking at 50 rpm. Following removal of the labeled probe solution, the membranes were washed 3 times at 25°C (50 rpm, 15 mm) in 3X SSC (about 150 ml each wash) They were then washed for 3 hr at 68 °C (50 rpm) -54- SUBSTTTUTE SHEET (RULE 26) 0.25X SSC plus 0.2% SDS (minimal hyb wash solution), and exposed to X-ray film as described above for 1.5 hr at 25°C (no enhancer screens) . This exposure revealed very strong hybridization signals to cosmid isolates 22G12, 25A10, 26A5, and 26B10, and a very weak signal with cosmid isolate 8B10. No signal was seen with the negative control (pWE15) colonies, and a very strong signal was seen with positive control membranes (DH5α cells containing the GZ4 isolate of the PCR product) that had been processed concurrently with the experimental samples. Amplification of a Specific Genomic Fragment of a TcaB Gene Based on the N-termmal ammo acid sequence determined for the purified TcaB 1 peptide fraction (disclosed here as SEQ ID NO.3) a pool of degenerate oligonucleotides (pool P8F) was synthesized as described for peptide TcaC.

A typical reaction (50 μl) contained (bottom layer) 25 pmol of each primer pool P8F and P8.108.3R, with 2 nmol each of dATP, dCTP, dGTP, and dTTP, m IX GeneAmp * PCR buffer, and (top layer) 230 ng of genomic template DNA, 8 nmol each of dATP, dCTP, dGTP, and dTTP, and 2 5 units of AmpliTaq * DNA polymerase, in IX GeneAmp " PCR buffer Amplifications were performed by 35 cycles as described for the TcaC peptide Amplification products were analyzed by electrophoresis through 0.7% w/v SeaKem" LE agarose (FMC) in TEA buffer. A specific product of estimated size 1600 bp was observed. Four such reactions were pooled, and the amplified DNA was extracted from a 1.0% SeaKeπT LE gel by Qiaex kit as described for the TcaC peptide. The extracted DNA was used directly as the template for sequence determination (PRISM 1 " Sequencing Kit) using the P8F and P8.108.3R primer pools. Each reaction contained about 100 ng template DNA and 25 pmol of one primer pool, and was processed according to standard protocols as described for the TcaC peptide. An analysis of the sequence derived from extension of the P8F primers revealed the short DNA sequence (and encoded ammo acid sequence) : GAT GCA TTG NTT GCT Asp Ala Leu (Val) Ala which corresponds to a portion of the N-termmal peptide sequence disclosed as SEQ ID NO: 3 (TcaBx) Labeling of a TcaB-. -peptide Gene-specific Probe Approximately 50 ng of gel -purified TcaBi DNA fragment was labeled with 32 P-dCTP as described above, and non corporated radioisotopes were removed by passage through a NICK Column ' (Pharmacia) . The specific activity of the labelled DNA was determined to be 6 x 10 9 dpm/μg This labeled DNA was used to probe colony membranes prepared from members of the genomic library that had hybridized to the TcaC-peptide specific probe. The membranes containing the 12 colonies identified m the TcaC-probe library screen (see above) were stripped of radioactive TcaC-specific label by boiling twice for approximately 30 mm each time in 1 liter of 0. IX SSC plus 0.1 % SDS. Removal of raαiolabel was checked with a 6 hr film exposure The stripped membranes were then incubated with the TcaB peptide-specific probe prepared above The labeled DNA was denatured by boiling for 10 mm, and then added to the filters that had been incubated for L hr in 100 ml of "minimal hyb" solution at 60°C. After overnight hybridization at this temperature, the probe solution was removed, and the filters were washed as follows (all 0.3X SSC plus 0.1% SDS) once for 5 mm at 25°C, once for 1 hr at 60°C m fresh solution, and once for 1 hr at 63 °C in fresh solution. After 1.5 hr exposure to X-ray film by standard procedures, 4 strongly- hybridizing colonies were observed. These were, as with the TcaC- specific probe, isolates 22G12, 25A10, 26A5, and 26B10 -56- SUBSTTTUTE SHEET (RULE 26) The same TcaBx probe solution was diluted with an equal volume (about 100 ml) of "minimal hyb" solution, and then used to screen the membranes containing the 800 members of the genomic library. After hybridization, washing, and exposure to X-ray film as described above, only the four cosmid clones 22G12, 25A10, 26A5, and 26B10, were found to hybridize strongly to this probe Isolation of Subclones Containing Genes Encoding TcaC and YcaB j Peptides. and Determination of DNA Base Sequence Thereof Three hybridization-positive cosmids in strain XLI Blue MR were grown with shaking overnight (200 rpm) at 30°C in 100 ml TB- Amp 100 . After harvesting the cells by centrifugation, cosmid DNA was prepared using a commercially available kit (BIGprep™, 5 Prime 3 Prime, Inc., Boulder, CO), following the manufacturer's protocols. Only one cosmid, 26A5, was successfully isolated by this procedure When digested with restriction enzyme EcoR 1 (NEB) and analyzed by gel electrophoresis, fragments of approximate sizes 14, 10, 8 (vector), 5, 3.3, 2.9, and 1 5 kbp were detected. A second attempt to isolate cosmid DNA from the same three strains (8 ml cultures; TB-Amp 100 , 30 °C) utilized a boiling mmiprep method (Evans G. and G. Wahl . , 1987, "Cosmid vectors for genomic walking and rapid restriction mapping." in Guide to Molecular Cloning Techniques. Meth. Enzymoloαy. Vol. 152, S. Berger and A. Kimmel, eds., pgs . 604-610). Only one cosmid, 25A10, was successfully isolated by this method. When digested with restriction enzyme EcoR I (NEB) and analyzed by gel electrophoresis, this cosmid showed a fragmentation pattern identical to that previously seen with cosmid 26A5. A 0.15 μg sample of 26A5 cosmid DNA was used to transform 50 ml of E. coli DH5α cells (Gibco BRL) , by the supplier's protocols. A single colony isolate of that strain was inoculated into 4 ml of TB-Amp 100 , and grown for 8 hr at 37°C. Chloramphenicol was added to a final concentration of 225 μg/ml, incubation was continued for another 24 hr, then cells were harvested by centrifugation and frozen at -20°C. Isolation of the 26A5 cosmid DNA was by a standard alkaline lysis mmiprep (Maniatis et al . , op . ci t . , p. 382) , modified by increasing all volumes by 50% and with stirring or gentle mixing, rather than vortexing, at every step. After washing the DNA pellet in 70% ethanol, it was dissolved TE containing 25 μg/ml ribonuclease A (Boehπnger Mannheim) Identification of EcoR I Fragments Hybridizing to GZ4 -derived and TcaB,_- Probes Approximately 0.4 μg of cosmid 25A10 (from XLI Blue MR cells) β'd about 0.5 μg of cosmid 26A5 (from chloramphenicol -amplified [ 5α cells) were each digested with about 15 units of EcoR I (NEB) for 85 mm, frozen overnight, then heated at 65 °C for five mm, and electrophoresed n a 0.7% agarose gel (Seake * LE, IX TEA, 80 volts, 90 m ) . The DNA was stained with ethidium bromide as described above, and photographed under ultraviolet light. The EcoR I digest of cosmid 25A10 was a complete digestion, but the sample of cosmid 26A5 was only partially digested under these conditions. The agarose gel containing the DNA fragments was subjected to depurmation, denaturation and neutralization, followed by Southern blotting onto a Magna NT nylon membrane, using a high salt (20X SSC) protocol, all as described in section 2.9 of Ausubel et al . (CPMB, op . ci t . ) The transferred DNA was then UV-crosslmked to the nylon membrane as before . An TcaC-peptide specific DNA fragment corresponding to the insert of plasmid isolate GZ4 was amplified by PCR° in a 100 ml reaction volume as described previously above. The amplification products from three such reactions were pooled and were extracted from a 1% GTG" agarose gel by Qiaex kit, as described above, and quantitated by fluorometry. The gel-purified DNA (100 ng) was labeled with 32 P-dCTP using the High Prime Labeling Mix (Boehrmger Mannheim) as described above, to a specific activity of 6 34 x 10 s dpm/μg. The 32 P-labeled GZ4 probe was boiled 10 mm, then added to "minimal hyb" buffer (at 1 ng/ml) , and the Southern blot membrane containing the digested cosmid DNA fragments was added, and incubated for 4 hr at 60°C with gentle shaking at 50 rpm. The membrane was then washed 3 times at 25°C for about 5 mm each (minimal hyb wash solution) , followed by two washes for 30 mm each at 60°C. The blot was exposed to film (with enhancer screens) for about 30 mm at -70°C The GZ4 probe hybridized strongly to the 5.0 kbp (apparent size) EcoR I fragment of both these two cosmids, 26A5 and 25A10. The membrane was stripped of radioactivity by boiling for about 30 mm in 0. IX SSC plus 0.1 % SDS, and absence of radiolabel was checked by exposure to film It was then hybridized at 60°C for 3.5 hours with the (denatured) TcaB probe "minimal hyb" buffer previously used for screening the colony membranes (above) , washed as described previously, and exposed to film for 40 mm at - -58- SUBSTΓΠJTE SHEET (RULE 26) 70°C with two enhancer screens. With both cosmids, the TcaBx probe hybridized lightly with the about 5 0 kbp EcoR 1 fragment, and strongly with a fragment of approximately 2.9 kbp . The sample of cosmid 26A5 DNA previously described, (from DH5α cells) was used as the source of DNA from which to subclone the bands of interest. This DNA (2.5 μg) was digested with about 3 units of EcoR I (NEB) a total volume of 30 μl for 1.5 hr, to give a partial digest, as confirmed by gel electrophoresis Ten μg of pBC KS (+) DNA (Stratagene) were digested for 1.5 hr with 20 units of EcoR I in a total volume of 20 μl , leading to total digestion as confirmed by electrophoresis Both EcoR I -cut DNA preparations were diluted to 50 μl with water, to each an equal volume of PCI was added, the suspension was gently mixed, spun in a microcentrifuge and the aqueous supernatant was collected. DNA was precipitated by 150 μl ethanol, and the mixture was placed at -20°C overnight. Following centrifugation and drying, the EcoR I - digested pBC KS (+) was dissolved in 100 μl TE, the partially digested 26A5 was dissolved in 20 μl TE DNA recovery was checked by fluorometry. In separate reactions, approximately 60 ng of EcoR I -digested pBC KS(+) DNA was ligated with approximately 180 ng or 270 ng of partially digested cosmid 26A5 DNA. Ligations were carried out m a volume of 20 μl at 15°C for 5 hr, using T4 ligase and buffer from New England BioLabs The ligation mixture, diluted to 100 μl with sterile TE, was used to transform frozen, competent DH5α cells (Gibco BRL) according to the supplier's instructions. Varying amounts (25-200 μl) of the transformed cells were plated on freshly prepared solid LB-Cam 35 medium with 1 mM IPTG and 50 mg/1 X-gal. Plate ' s ' were " incubated at 37 °C about 20 hr, then chilled the dark for approximately 3 hr to intensify color for ιnsertr ~ selectιon. White colonies were picked onto patch plates of the same composition and incubated overnight at 37°C. Two colony lifts of each of the selected patch plates were prepared as follows. After picking white colonies to fresh plates, round Magna NT nylon membranes were pressed onto the patch plates, the membrane was lifted off, and subjected to denaturation, neutralization and UV crosslmk g as described above for the library colony membranes. The crosslmked colony lifts were vigorously washed, including gently wiping off the excess cell debris with a tissue. One set was hybridized with the GZ4 (TcaC) probe solution described earlier, and the other set was hybridized with the TcaBx probe solution described earlier, according to the -59- SUBSTΪTUTE SHEET (RULE 26) 'minimal hyb' protocol, followed by washing and film exposure as described for the library colony membranes. Colonies showing hybridization signals either only with the GZ4 probe, with both GZ4 and TcaBi probes, or only with the TcaBi probe, were selected for further work and cells were streaked for single colony isolation onto LB-Cam 3r media with IPTG and X-gal as before. Approximately 35 single colonies, from 16 different isolates, were picked into liquid LB-Cam 35 media and grown overnight at 37°C; the cells were collected by centrifugation and plasmid DNA was isolated by a standard alkaline lysis mmiprep according to Maniatis et al . [ op. ci t . p. 368). DNA pellets were dissolved in TE + 25 μg/ml πbonuclease A and DNA concentration was determined by fluorometry. The EcoR I digestion pattern was analyzed by gel electrophoresis. The following isolates were picked as useful. Isolate A17.2 contains religated pBC KS(+) only and was used for a (negative) control. Isolates D38.3 and C44 1 each contain only the 2.9 kbp, TcaBi -hybridizing EcoR I fragment inserted into pBC KS(+) These plasmids, named pDAB2000 and pDAB2001, respectively, are illustrated in Fig. 2. Isolate A35.3 contains only the approximately 5 kbp, GZ4)- hybπdizmg EcoR 1 fragment, inserted into pBC KS(+ ) This plasmid was named pDAB2002 (also Fig. 2) These isolates provided templates for DNA sequencing. Plasmids pDAB2000 and pDAB2001 were prepared using the BIGprep™ kit as before Cultures (30 ml) were grown overnight in TB-Cam 35 to an OD 600 of 2, then plasmid was isolated according to the manufacturer's directions. DNA pellets were redissolved in 100 μl TE each, and sample integrity was checked by EcoR I digestion and gel electrophoretic analysis. Sequencing reactions were run in duplicate, with one replicate using as template pDAB2000 DNA, and the other replicate using as template pDAB2001 DNA. The reactions were carried out using the dideoxy dye terminator cycle sequencing method, as described above for the sequencing of the GZ4/HB14 DNAs Initial sequencing runs utilized as primers the LacZ and T7 primers described above, plus primers based on the determined sequence of the TcaB t PCR amplification product (THl = ATTGCAGACTGCCAATCGCTTCGG , TH12 = GAGAGTATCCAGACCGCGGATGATCTG) . After alignment and editing of each sequencing output, each was truncated to between 250 to 350 bases, depending on the integrity of the chromatographic data as interpreted by the Perkm Elmer Applied Biosyste s Division SeqEd 675 software Subsequent -60- SUBSTΓΓUTE SHEET (RULE 26) sequencing "steps" were made by selecting appropriate sequence for new primers. With a few exceptions, primers (synthesized as described above) were 24 bases in length with a 50% G+C composition. Sequencing by this method was carried out on both strands of the approximately 2.9 kbp EcoR I fragment . To further serve as template for DNA sequencing, plasmid DNA from isolate pDAB2002 was prepared by BIGprep™ kit. Sequencing reactions were performed and analyzed as described above. Initially, a T3 primer (pBS SK (+) bases 774-796: CGCGCAATTAACCCTCACTAAAG) and a T7 primer (pBS KS (+) bases 621-643: GCGCGTAATACGACTCACTATAG) were used to prime the sequencing reactions from the flanking vector sequences, reading into the insert DNA. Another set of primers, (GZ4F: GTATCGATTACAACGCTGTCACTTCCC; THl3 : GGGAAGTGACAGCGTTGTAATCGATAC; TH14: ATGTTGGGTGCGTCGGCTAATGGACATAAC ; and LW1-204 : GGGAAGTGACAGCGTTGTAATCGATAC) was made to prime from internal sequences, which were determined previously by degenerate oligonucleotide-mediated sequencing of subcloned TcaC-peptide PCR products. From the data generated during the initial rounds of sequencing, new sets of primers were designed and used to walk the entire length of the about 5 kbp fragment. A total of 55 oligo primers was used, enabling the identification of 4832 total bp of contiguous sequence. When the DNA sequence of the EcoR I fragment insert of pDAB2002 is combined with part of the determined sequence of the pDAB2000/pDAB2001 isolates, a total contiguous sequence of 6005 bp was generated (disclosed herein as SEQ ID NO: 25) . When long open reading frames were translated into the corresponding ammo acids, the sequence clearly shows the TcaBi N-terminal peptide (disclosed as SEQ ID NO:3), encoded by bases 68-124, immediately following a methionine residue (start of translation) . Upstream lies a potential ribosome binding site (bases 51-58) , and downstream, at bases 215-277 is encoded the TcaBi-PT158 internal peptide (disclosed herein as SEQ ID NO: 19) . Further downstream, m the same reading frame, at bases 1787-1822, exists a sequence encoding the TcaBi-PT108 internal peptide (disclosed herein as SEQ ID NO:20) . Also in the same reading frame, at bases 1946-1972, is encoded the TcaBϋ N-terminal peptide (disclosed herein -as SEQ ID NO: 5), and the reading frame continues uninterrupted to a translation termination codon at nucleotides 3632-3634. The lack of an in- frame stop codon between the end of the sequence encoding TcaB 1 -PT108 and the start of the TcaBϋ encoding -61- SUBSTΓΓUTE SHEET (RULE 26) region, and the lack of a discernible πbosome binding site immediately upstream of the TcaB n coding region, indicate that peptides TcaB lx and TcaB x are encoded by a single open reading frame of 3567 bp beginning at base pair 65 in SEQ ID NO:25), and are most likely derived from a single primary gene product TcaB of 1189 ammo acids (131,586 Daltons; disclosed herein as SEQ ID NO: 26) by post-translational cleavage. If the am o acid immediately preceding the TcaB xl N-termmal peptide represents the C-termmal ammo acid of peptide , then the predicted mass of TcaB n (627 ammo acids) is 70,814 Daltons (disclosed herein as SEQ ID NO:28) , somewhat higher than the size observed by SDS-PAGE (68 kDa) This peptide would be encoded by a contiguous stretch of 1881 base pairs (disclosed herein as SEQ ID NO:27) It is thought that the native C-termmus of TcaB x lies somewhat closer to the C- terminus of TcaBi-PTlOΘ. The molecular mass of PT108 [3.438 kDa, determined during N-termmal ammo acid sequence analysis of this peptide] predicts a size of 30 ammo acids Using the size of this peptide to designate the C-termmus of the TcaB x coding region [Glu at position 604 of SEQ ID NO: 28] , the derived size of TcaB x is determined to be 604 am o acids or 68,463 Daltons, more in agreement with experimental observations. Translation of the TcaB n peptide coding region of 1686 base pairs (disclosed herein as SEQ ID NO:29) yields a protein of 562 ammo acids (disclosed herein as SEQ ID NO 30) with predicted mass of 60,789 Daltons, which corresponds well with the observed 61 kDa A potential ribosome binding site (bases 3682-3687) is found 48 bp downstream of the stop codon for the tcaB open reading frame At bases 3694-3726 is found a sequence encoding the N-terminus of peptiαe TcaC, (disclosed as SEQ ID NO.2) The open reading frame initiated by this N-termmal peptide continues uninterrupted to base 6005 (2361 base pairs, disclosed herein as the first 2361 base pairs of SEQ ID NO.31) A gene ( tcaC) encoding the entire TcaC peptide, (apparent size about 165 kDa, about 1500 ammo acids) , would comprise about 4500 bp . Another isolate containing cloned EcoR I fragments of cosmid 26A5, E20.6, was also identified by its homology to the previously mentioned GZ4 and TcaB probes Agarose gel analysis of EcoR I digests of the DNA of the plasmid harbored by this strain (pDAB2004, Fig. 2), revealed insert fragments of estimated sizes 2.9, 5, and 3 3 kbp. DNA sequence analysis initiated from primers designed from the sequence of plasmid pDAB2002 revealed that the -62- SUBSTΓΓUTE SHEET (RULE 26) 3.3 kbp EcoR I fragment of pDAB2004.lies adjacent to the 5 kbp EcoR I fragment represented in pDAB2002. The 2361 base pair open reading frame discovered in pDAB2002 continues uninterrupted for another 2094 bases in pDAB2004 [disclosed herein as base pairs 2362 to 4458 of SEQ ID NO: 31] . DNA sequence analysis using the parent cosmid 26A5 DNA as template confirmed the continuity of the open reading frame. Altogether, the open reading frame ( tcaC SEQ ID NO: 31) comprises 4455 base pairs, and encodes a protein (TcaC) of 1485 amino acids [disclosed herein as SEQ ID NO: 32] . The calculated molecular size of 166,214 Daltons is consistent with the estimated size of the TcaC peptide (165 kDa) , and the derived amino acid sequence matches exactly that disclosed for the TcaC N- terminal sequence [SEQ ID NO: 2] . The lack of an amino acid sequence corresponding to SEQ ID NO: 17; used to design the degenerate oligonucleotide primer pool in the discovered sequence indicates that the generation of the PCR ® products found in isolates GZ4 and HB14, which were used as probes in the initial library screen, were fortuitously generated by reverse-strand priming by one of the primers in the degenerate pool. Further, the derived protein sequence does not include the internal fragment disclosed herein as SEQ ID NO: 18. These sequences reveal that plasmid pDAB2004 contains the complete coding region for the TcaC peptide. Further analysis of SEQ ID NO: 25 reveals the end of an open reading frame (bases 1-43), which encodes the final 13 amino acids of the TcaA iι:L peptide, disclosed herein as SEQ ID NO: 35. Only 24 bases separate the end of the TcaA i3 _i coding region and the start of the TcaBi coding region. Included within the 24 bases are sequences that may serve as a ribosome binding site. Although possible, it is not likely that a Photorhabdus gene promoter is encoded within this short region. We propose that genomic region tea, which includes three long open reading frames [ tcaA (SEQ ID NO:33), tcaB (SEQ ID NO:25, bases 65-36334), and tcaC (SEQ ID NO:31) , which is separated from the end of tcaB by only 59 bases] is regulated as an operon, with transcription initiating upstream of the start of the tcaA gene (SEQ ID NO:33), and resulting in a polycistronic messenger RNA. -63- SUBSTΓΓUTE SHEET (RULE 26) Example 9 Scre ning of the PhQtQrhabύ s Genomic Library for Genes Encoding the TcbA^ Peptide This example describes a method used to identify DNA clones that contain the TcbA xl peptide-encoding genes, the isolation of the gene, and the determination of its partial DNA base sequence. Primers and PCR Reactions The TcbAn polypeptide of the insect active preparation is about 206 kDa. The ammo acid sequence of the N-terminus of this peptide is disclosed as SEQ ID NO:l. Four pools of degenerate oligonucleotide primers ("Forward primers"- TH-4, TH-5, TH-6, and TH-7) were synthesized to encode a portion of this ammo acid sequence, as described in Example 8, and are shown below Table 12 Amino Acid Phe lie Gin Gly Tyr Ser Asp Leu Phe TH-4 5'-TT(T/C) ATI CA(A/G) GGI TA(T/C) TCI GA(T/C) CTI TT- 3' TH-5 5'-TT(T/C) ATI CA(A/G) GGI TA(T/C) AG(T/C) GA(T/C) CTI TT- 3' TH-6 5'-TT(T/C) ATI CA(A/G) GGI TA(T/C) TCI GA(T/C) TT(A/G) TT- 3' TH-7 5'-TT(T/C) ATI CA(A/G) GGI TA(T/C) AG(T/C) GA(T/C) TT(A/G) TT- 3' In addition, a primary ("a") and a secondary ("b") sequence of an internal peptide preparation (TcbAn-PT81) have been determined and are disclosed herein as SEQ ID NO: 23 and SEQ ID NO: 24, respectively Four pools of degenerate oligonucleotides ("Reverse Primers": TH-8, TH-9, TH-10 and TH-11) were similarly designed and synthesized to encode the reverse complement of sequences that encode a portion of the peptide of SEQ ID NO: 23, as shown below.

All PC reactions were run with the "Hot Start" technique using AmpliWax™ gems and other Perk Elmer reagents and protocols. Typically, a mixture (total volume 11 μl) of MgCl 2 , dNTP ' s , 10X GeneAmp' PCR Buffer II, and the primers were added to tubes containing a single wax bead. [10X GeneAmp" PCR Buffer II is composed of 100 mM Tris-HCl, pH 8.3; and 500 mM KC1.] The tubes were heated to 80 °C for 2 minutes and allowed to cool. To the top of the wax seals, a solution containing 10X GeneAmp" PCR Buffer II, DNA template, and A pliTaq ® DNA polymerase were added. Following melting of the wax seal and mixing of components by thermal cycling, final reaction conditions (volume of 50 μl) were: 10 mM Tris-HCl, pH 8.3; 50 mM KC1; 2.5 mM MgCl 2 ; 200 μM each in dATP, dCTP, dGTP, dTTP; 1.25 mM in a single Forward primer pool; 1.25 μM in a single Reverse primer pool, 1.25 units of AmpliTaq" DNA polymerase, and 170 ng of template DNA. The reactions were placed in a thermocycler (as m Example 8) and run with the following program: Table 14 A series of amplifications was run at three different annealing tempera ures (55°, 60°, 65°C) using the degenerate primer -66- SUBSTΓΓUTE SHEET (RULE 26) pools. Reactions with annealing at .65°C had no amplification products visible following agarose gel electrophoresis. Reactions having a 60°C annealing regime and containing primers TH-5+TH-10 produced an amplification product that had a mobility corresponding to 2.9 kbp. A lesser amount of the 2.9 kbp product was produced under these conditions with primers TH-7+TH-10. When reactions were annealed at 55°C, these primer pairs produced more of the 2.9 kbp product, and this product was also produced by primer pairs TH- 5+TH-8 and TH-5+TH-11. Additional very faint 2.9 kbp bands were seen in lanes containing amplification products from primer pairs TH-7 plus TH-8, TH-9, TH-10, or TH-11. To obtain sufficient PCR amplification product for cloning and DNA sequence determination, 10 separate PCR reactions were set up using the primers TH-5+TH-10, and were run using the above conditions with a 55°C annealing temperature. All reactions were pooled and the 2.9 kbp product was purified by Qiaex extraction from an agarose gel as described above. Additional sequences determined for TcbAϋ internal peptides are disclosed herein as SEQ ID NO: 21 and SEQ ID NO: 22. As before, degenerate oligonucleotides (Reverse primers TH-17 and TH-18) were made corresponding to the reverse complement of sequences that encode a portion of the amino acid sequence of these peptides.

These reactions amplified products of approximately 4 kbp and 4.5 kbp, respectively. These DNAs were transferred from 32 agarose gels to nylon membranes and hybridized with a P-labeled probe (as described above) prepared from the 2.9 kbp product amplified by the TH-5+TH10 primer pair. Both the 4 kbp and the 4.5 kbp amplification products hybridized strongly to the 2.9 kbp probe. These results were used to construct a map ordering the TcbAii internal peptide sequences as shown in Fig. 3 Approximate distances between the primers are shown in nucleotides in Fig. 3. DNA Sequence of the 2.9 kbp TcbA-, -, -encoding Fragment Approximately 200 ng of the purified 2.9 kbp fragment (prepared above) was precipitated with ethanol and dissolved m 17 ml of water. One-half of this was used as sequencing template with 25 pmol of the TH-5 pool as primers, the other half was used as template for TH-10 priming. Sequencing reactions were as given in Example 8. No reliable sequence was produced using the TH-10 primer pool; however, reactions with TH-5 primer pool produced the sequence disclosed below: . 1 AATCGTGTTG ATCCCTATGC CGNGCCGGGT TCGGTGGAAT CGATGTCCTC ACCGGGGGTT 61 TATTNGAGGG ANTNGTCCCG TGAGGCCAAA AATGGAATG AAAGAAGTTC AATTTNTTAC 121 CTAGATAAAC GTCGCCCGGN TTTAGAAAGN TTATGNTCA GCCAGAAAAT TTTGGTTGAG 181 GAAATTCCAC CGNTGGTTCT CTCTATTGAT TNGGGCCTGG CCGGGTTCGA ANNAAAACNA 241 GGAAATNCAC AAGTTGAGGT GATGGNTTTG TNGCNANCTT NTCGTTTAGG TGGGGAGAAA 301 CCTTNTCANC ACGNTTNTGA AACTGTCCGG GAAATCGTCC ATGANCGTGA NCCAGGNTTN 361 CGCCATTGG Based on this sequence, a sequencing primer (TH-21, 5'- CCGGGCGACGTTTATCTAGG-3 ' ) was designed to reverse complement bases 120-139, and initiate polymerization towards the 5' end (i.e., TH-5 end) of the gel -purified 2.9 kbp TcbA x -encoding PCR fragment. The determined sequence is shown below, and is compared to the biochemically determined N-termmal peptide sequence of TcbA xx SEQ ID N0:1.

This 2.9 kbp fragment was then used as a hybridization probe to screen the Photorhabdus W-14 genomic library prepared in Example 8 for cosmids containing the TcbA xl -encoding gene. -68- SUBSTΓΓUTE SHEET (RULE 26) Screening the Photorhabdus Cosmid Library The 2.9 kb gel-purified PCR fragment was labeled with 32 P using the Boehrmger Mannheim High Prime labeling kit as described m Example 8. Filters containing remnants of approximately 800 colonies from the cosmid library were screened as described previously (Example 8) , and positive clones were streaked for isolated colonies and rescreened. Three clones (8A11, 25G8, and 26D1) gave positive results through several screening and characterization steps. No hybridization of the TcbA x -specιfic probe was ever observed with any of the four cosmids identified in Example 8 , and which contain the tcaB and tcaC genes . DNA from cosmids 8All, 25G8 , and 26D1 was digested with restriction enzymes Bgl II, EcoR I or Hind III (either alone or combination with one another) , and the fragments were separated on an agarose gel and transferred to a nylon membrane as described in Example 8 The membrane was hybridized with 32 P- labeled probe prepared from the 4.5 kbp fragment (generated by amplification of Photorhabdus genomic DNA with primers TH-5+TH-17) . The patterns generated from cosmid DNAs 8A11 and 26D1 were identical to those generated with similarly-cut genomic DNA on the same membrane. It is concluded that cosmids 8A11 and 26D1 are accurate representations of the genomic TcbA xx encoding locus. However, cosmid 25G8 has a single Bgl II fragment which is slightly larger than the genomic DNA. This may result from positioning of the insert withm the vector. DNA Sequence of the tcbA-encoding Gene The membrane hybridization analysis of cosmid 26D1 revealed that the 4.5 kbp probe hybridized to a single large EcoR I fragment (greater than 9 kbp) This fragment was gel purified and ligated into the EcoR I site of pBC KS (+) as described in Example 8, to generate plasmid pBC-Sl/Rl. The partial DNA sequence of the insert DNA of this plasmid was determined by "primer walking" from the flanking vector sequence, using procedures described in Example 8. Further sequence was generated by extension from new oligonucleotides designed from the previously determined sequence. When compared to the determined DNA sequence for the tcbA gene identified by other methods (disclosed herein as SEQ ID NO: 11 as described in Example 12 below) , complete homology was found to nucleotides 1-272, 319-826, 2578-3036, and 3068-3540 (total bases = 1712) . It was concluded that both approaches can be used to identify DNA fragments encoding the TcbA lx peptide -69- SUBSTΓΓUTE SHEET (RULE 26) Analysis of the Derived Amino Acid Sequence of the tcbA Gene The sequence of the DNA fragment identified as SEQ ID NO: 11 encodes a protein whose derived amino acid sequence is disclosed herein as SEQ ID NO: 12. Several features verify the identity of the gene as that encoding the TcbA protein. The TcbA xx N- terminal peptide (SEQ ID NO.-l; Phe lie Gin Gly Tyr Ser Asp Leu Phe Gly Asn Arg Ala) is encoded as amino acids 88-100. The TcbA xx internal peptide TcbA xx -PT81 (a) (SEQ ID NO: 23) is encoded as amino acids 1065-1077, and TcbA xx -PT81 (b) (SEQ ID NO:24) is encoded as amino acids 1571-1592. Further, the internal peptide TcbA xx -PT56 (SEQ ID NO:22) is encoded as amino acids 1474-1488, and the internal peptide TcbA xx -PT103 (SEQ ID NO: 21) is encoded as amino acids 1614-1639. It is obvious that this gene is an authentic clone encoding the TcbA xx peptide as isolated from insecticidal protein preparations of Photorhabdus luminescens strain W-14. The protein isolated as peptide TcbA xx is derived from cleavage of a longer peptide. Evidence for this is provided by the fact that the nucleotides encoding the TcbA xx N-terminal peptide SEQ ID NO:l are preceded by 261 bases (encoding 87 N- terminal - proximal amino acids) of a longer open reading frame (SEQ ID NO:ll). This reading frame begins with nucleotides that encode the amino acid sequence Met Gin Asn Ser Leu, which corresponds to the N-terminal sequence of the large peptide TcbA, and is disclosed herein as SEQ ID NO: 16. It is thought that TcbA is the precursor protein for TcbA xx . Relationship of tcbA . tcaB and tcaC Genes The tcaB and tcaC genes are closely linked and may be transcribed as a single mRNA (Example 8) . The tcbA gene is borne on cosmids that apparently do not overlap the ones harboring the tcaB and tcaC cluster, since the respective genomic library screens identified different cosmids. However, comparison of the amino sequences encoded by the tcaB and tcaC genes with the tcbA gene reveals a substantial degree of homology. The amino acid conservation (Protein Alignment Mode of MacVector™ Sequence Analysis Software, scoring matrix pam250, hash value = 2; Oxford Molecular Group, Campbell, CA) is shown in Fig. 4. On the score line of each panel in Fig. 4, up carats ( A ) indicate homology or conservative amino acid changes, and down carats (v) indicate nonhomo1ogy . -70- SUBSTΓΓUTE SHEET (RULE 26) This analysis shows that the ammo acid sequence of the TcbA peptide from residues 1739 to 1894 is highly homologous to ammo acids 441 to 603 of the TcaB x peptide (162 of the total 627 ammo acids of TcaB; SEQ ID NO: 28) . In addition, the sequence of TcbA ammo acids 1932 to 2459 is highly homologous to ammo acids 12 to 531 of peptide TcaB lx (520 of the total 562 amino acids; SEQ ID NO:30) . Considering that the TcbA peptide (SEQ ID NO:12) comprises 2505 ammo acids, a total of 684 ammo acids (27%) at the C- proximal end of it is homologous to the TcaB x or TcaB lx peptides, and the homologies are arranged colmear to the arrangement of the putative TcaB preprotem (SEQ ID NO:26) . A sizeable gap in the TcbA homology coincides with the junction between the TcaB χ and TcaB xl portions of the TcaB preprotem. Clearly the TcbA and TcaB gene products are evolutionarily related, and it is proposed that they share some common functio (s) Photorhabdus . Example 10 Characterization of Zmc-metalloproteases in Photorhabdus Broth: Protease Inhibition. Classification, and Purification Protease Inhibition and Classification Assays: Protease assays were performed using FITC-casem dissolved water as substrate (0.08% final assay concentration) . Proteolysis reactions were performed at 25°C for 1 h in the appropriate buffer with 25 μl of Photorhabdus broth (150 μl total reaction volume) . Samples were also assayed the presence and absence of dithiothreitol After incubation, an equal volume of 12% tπchloroacetic acid was added to precipitate undigested protein. Following precipitation for 0.5 h and subsequent centrifugation, 100 μl of the supeTnatant was placed into a 96-well microtiter plate and the pH of the solution was adjusted by addition of an equal volume of 4N NaOH. Proteolysis was then quantitated using a Fluoroskan II fluorometric plate reader at excitation and emission wavelengths of 485 and 538 nm, respectively. Protease activity was tested over a range from pH 5.0-10.0 in 0.5 units increments. The following buffers were used at 50 mM final concentration: sodium acetate (pH 5.0 - 6.5); Tris-HCL (pH 7 0 - 8.0); and bis-Tris propane (pH 8 5-10.0). To identify the class of protease (s) observed, crude broth was treated with a variety of protease inhibitors (0.5 μg/μl final concentration) and then examined for protease activity at pH 8.0 -71- SUBSTΪTUTE SHEET (RULE 26) using the substrate described above. The protease inhibitors used mcluded E-64 (L-trans-expoxysacc ylleucylamido [4- , -guanidmo] - butane), 3,4 dichloroisocσumarm, Leupeptin, pepstatm, amastat , ethylenediammetetraacetic acid (EDTA) and 1,10 phenanthrolme. Protease assays performed over a pH range revealed that indeed protease (s) were present which exhibited maximal activity at about pH 8.0 (Table 17) . Addition of DTT did not have any effect on protease activity. Crude broth was then treated with a variety of protease inhibitors (Table 18) Treatment of crude broth with the inhibitors described above revealed that 1,10 phenanthrolme caused complete inhibition of all protease activity when added at a final concentration of 50 μg, with the IC50 = 5 μg in 100 μl of a 2 mg/ml crude broth solution. These data indicate that the most abundant protease (s) found m the Photorhabdus broth are from the zmc- metalloprotease class of enzymes Table 17 Effect of pH on the Protease Activity Found m a Day 1 Production of Photorhabdus luminescens (Strain W-14) pH Flu.

The isolation of a z c-metalloprotease was performed by applying dialyzed 10-80% ammonium sulfate pellet to a Q Sepharose column equilibrated at 50 mM Na2P04, pH 7.0 as described m Example 5 for Photorhabdus toxin After extensive washing, a 0 to 0.5 M NaCl gradient was used to elute toxm protein. The majority of biological activity and protein was eluted from 0.15 - 0.45 M NaCl. However, it was observed that the majority of proteolytic activity was present in the 0.25-0.35 M NaCl fraction with some activity in the 0 15-0.25 M NaCl fraction SDS PAGE analysis of the 0.25-0.35 M NaCl fraction showed a major peptide band of approximately 60 kDa. The 0.15-0.25 M NaCl fraction contained a similar 60 kDa band but at lower relative protein concentration. Subsequent gel filtration of this fraction using a Superose 12 HR 16/50 column resulted m a major peak migrating at 57.5 kDa that contained a predominant (> 90% of total stained protein) 58.5 kDa band by SDS PAGE analysis. Additional analysis of this fraction using various protease inhibitors as described above determined that the protease was a zmc-metalloprotease. Nearly all of the protease activity present in Photorhabdus broth at day 1 of fermentation corresponded to the about 58 kDa zmc-metalloprotease. In yet a second isolation of zmc-metalloprotease (s) , W-14 Photorhabdus broth grown for three days was taken and protease activity was visualized using sodium dodecyl sulfate-polyacrylamide - 73- SUBSTΓΓUTE SHEET (RULE 26) gel electrophoresis (SDS-PAGE) laced with gelatin as described m Schmidt, T.M., Bleakley, B. and Nealson, K.M. 1988. SDS running gels (5.5 x 8 cm) were made with 12.5 % polyacrylamide (40% stock solution of acrylamide/bis-acrylamide; Sigma Chemical Co., St. Louis, MO) into which 0.1% gelatin final concentration (Biorad EIA grade reagent; Richmond CA) was incorporated upon dissolving m water. SDS-stackmg gels (1.0 x 8 cm) were made with 5% polyacrylamide, also laced with 0.1% gelatin. Typically, 2.5 μg of protein to be tested was diluted 0.03 ml of SDS-PAGE loading buffer without dithiothreitol (DTT) and loaded onto the gel. Proteins were electrophoresed in SDS running buffer (Laemmli, U.K. 1970 Nature 227, 680) at 0° C and at 8 mA After electrophoresis was complete, the gel was washed for 2 h in 2.5% (v/v) Triton X- 100. Gels were then incubated for 1 h at 37 °C in 0 1 M glycme (pH 8.0). After incubation, gels were fixed and stained overnight with 0.1% amido black in methanol -acetic acid- water (30.10-60, vol . /vol . /vol . ; Sigma Chemical Co.). Protease activity was visualized as light areas against a dark, amido black stained background due to proteolysis and subsequent diffusion of incorporated gelatin. At least three distinct bands produced by proteolytic activity at 58-, 41-, and 38 kDa were observed Activity assays of the different proteases in W-14 day three culture broth were performed using FITC-case dissolved in water as substrate (0.02% final assay concentration) Proteolysis experiments were performed at 37°C for 0-0 5 h in 0. IM Tris-HCl (pH 8.0) with different protein fractions in a total volume of 0 15 ml. Reactions were terminated by addition of an equal volume of 12% trichloroacetic acid (TCA) dissolved in water. After incubation at room temperature for 0.25 h, samples were centrifuged at 10,000 x g for 0.25 h and 0.10 ml aliquots were removed and placed into 96- well microtiter plates. The solution was then neutralized by the addition of an equal volume of 2 N sodium hydroxide, followed by quantitation using a Fluoroskan II fluorometπc plate reader with excitation and emission wavelengths of 485 and 538 nm, respectively Activity measurements were performed using FITC- Casein with different protease concentrations at 37°C for 0-10 mm A unit of activity was arbitrarily defined as the amount of enzyme needed to produce 1000 fluorescent units/mm and specific activity was defined as umts/mg of protease. - 74 - SUBSTΓΓUTE SHEET (RULE 26) Inhibition studies were performed using two zinc- metalloprotease inhibitors; 1,10 phenanthroline and N- (a- rhamnopyranosyloxyhydroxyphosphinyl) -Leu-Trp (phosphoramidon) with stock solutions of the inhibitors dissolved in 100% ethanol and water, respectively. Stock concentrations were typically 10 mg/ml and 5 mg/ml for 1,10 phenanthroline and phosphoramidon, respectively, with final concentrations of inhibitor at 0.5-1.0 mg/ml per reaction. Treatment of three day W-14 crude broth with 1,10 phenanthroline, an inhibitor of all zinc metalloproteases , resulted in complete elimination of all protease activity while treatment with phosphoramidon, an inhibitor of ther olysin-like proteases (Weaver, L.H., Kester, W.R., and Matthews, B.W. 1977. J. Mol. Biol. 114, 119-132), resulted in about 56% reduction of protease activity. The residual proteolytic activity could not be further reduced with additional phosphoramidon. The proteases of three day W-14 Photorhabdus broth were purified as follows: 4.0 liters of broth were concentrated using an Amicon spiral ultra filtration cartridge Type SIYIOO attached to an Amicon M-12 filtration device. The flow-through material having native proteins less than 100 kDa in size (3.8 L) was concentrated to 0.375 L using an Amicon spiral ultra filtration cartridge Type S1Y10 attached to an Amicon M-12 filtration device. The retentate material contained proteins ranging in size from 10-100 kDa. This material was loaded onto a Pharmacia HR16/10 column which had been packed with PerSeptive Biosystem (Framington, MA) Poros ® 50 HQ strong anion exchange packing that had been equilibrated in 10 mM sodium phosphate buffer (pH 7.0) . Proteins were loaded on the column at a flow rate of 5 ml/min, followed by washing unbound protein with buffer until A28O = 0.00. Afterwards, proteins were eluted using a NaCl gradient of 0-1.0 M NaCl in 40 min at a flow rate of 7.5 ml/min. Fractions were assayed for protease activity, supra., and active fractions were pooled. Proteolytically active fractions were diluted with 50% (v/v) 10 mM sodium phosphate buffer (pH 7.0) and loaded onto a Pharmacia HR 10/10 Mono Q column equilibrated in 10 mM sodium phosphate. After washing the column with buffer until A28O = 0.00, proteins were eluted using a NaCl gradient of 0-0.5 M NaCl for 1 h at a flow rate of 2.0 ml/min. Fractions were assayed for protease activity. Those fractions having the greatest amount of phosphoramidon-sensitive protease activity, the phosphoramidon sensitive activity being due to the 41/38 kDa protease, infra . , were pooled. These fractions were found to elute at a range of 0.15-0.25 M NaCl. Fractions containing a predominance of phosphoramidon- insensitive protease activity, the 58 kDa protease, were also pooled. These fractions were found to elute at a range of 0.25-0.35 M NaCl. The phosphoramidon-sensitive protease fractions were then concentrated to a final volume of 0.75 ml using a Millipore Ultrafree ® -15 centrifugal filter device Bιomax-5K NMWL membrane. This material was applied at a flow rate of 0.5 ml/mm to a Pharmacia HR 10/30 column that had been packed with Pharmacia Sephadex G-50 equilibrated m 10 mM sodium phosphate buffer (pH 7.0)/ 0.1 M NaCl. Fractions having the maximal phosphoramidon-sensitive protease activity were then pooled and centrifuged over a Millipore Ultrafree ® - 15 centrifugal filter device Bιomax-50K NMWL membrane. Proteolytic activity analysis, supra . , indicated this material to have only phosphoramidon-sensitive protease activity. Pooling of the phosphoramidon-insensitive protease, the 58 kDa protein, was followed by concentrating in a Millipore Ultrafree ® -15 centrifugal filter device Bιomax-50K NMWL membrane and further separation on a Pharmacia Superdex-75 column. Fractions containing the protease were pooled. Analysis of purified 58- and 41/38 kDa purified proteases revealed that, while both types of protease were completely inhibited with 1,10 phenanthrolme, only the 41/38 kDa protease was inhibited with phosphoramidon. Further analysis of crude broth indicated that protease activity of day 1 W-14 broth has 23% of the total protease activity due to the 41/38 kDa protease, increasing to 44% day three W-14 broth. Standard SDS-PAGE analysis for examining protein purity and obtaining ammo terminal sequence was performed using 4-20% gradient MmiPlus SepraGels purchased from Integrated Separation Systems (Natick, MA) . Proteins to be ammo-terminal sequenced were blotted onto PVDF membrane following purification, infra . , (ProBlott™ Membranes, Applied Biosyste s, Foster City, CA) , visualized with 0.1% amido black, excised, and sent to Cambridge Prochem,- Cambridge, MA, for sequencing. Deduced ammo terminal sequence of the 58- (SEQ ID NO:45) and 41/ " kDa (SEQ ID N0:44) proteases from three day old W-14 broth -76- SUBSTΓΓUTE SHEET (RULE 26) were DV-GSEKANEKLK (SEQ ID NO: 45) and DSGDDDKVTNTDIHR (SEQ ID NO: 44), respectively. Sequencing of the 41/38 kDa protease revealed several ammo termini, each one having an additional ammo acid removed by proteolysis. Examination of the primary, secondary, tertiary and quartenary sequences for the 38 and 41 kDa polypeptides allowed for deduction of the sequence shown above and revealed that these two proteases are homologous . Example 11. Part A Screening of Photorhabdus Genomic Library Via Use of Antibodies for Genes Encoding TcbA Peptide In parallel to the sequencing described above, suitable probing and sequencing was done based on the TcbA x peptide (SEQ ID NO:l) . This sequencing was performed by preparing bacterial culture broths and purifying the tox as described m Examples 1 and 2 above . Genomic DNA was isolated from the Photorhabdus l uminescens strain W-14 grown in Grace's insect tissue culture medium The bacteria were grown in 5 ml of culture medium in a 250 ml Erlenmeyer flask at 28 °C and 250 rpm for approximately 24 hours Bacterial cells from 100 ml of culture medium were pelleted at 5000 x g for 10 minutes. The supernatant was discarded, and the cell pellets then were used for the genomic DNA isolation. The genomic DNA was isolated using a modification of the CTAB method described in Section 2.4.3 of Ausubel [ supra . ) The section entitled "Large Scale CsCl prep of bacterial genomic DNA" was followed through step 6. At this point, an additional chloroform/isoamyl alcohol (24:1) extraction was performed followed by a phenol/chloroform/isoamyl (25:24:1) extraction step and a final chloroform/isoamyl/alcohol (24:1) extraction. The DNA was precipitated by the addition of a 0.6 volume of isopropanol . The precipitated DNA was hooked and wound around the end of a bent glass rod, dipped briefly into 70% ethanol as a final wash, and dissolved m 3 ml of TE buffer. The DNA concentration, estimated by optical density at 280/260 nm, was approximately 2 mg/ml. Using this genomic DNA, a library was prepared Approximately 50 μg of genomic DNA was partly digested with Sau3 Al . Then NaCl density gradient centrifugation was used to size fractionate the partially digested DNA fragments. Fractions containing DNA -77 - SUBSTTTUTE SHEET (RULE 26) fragments with an average size of 12 kb, or larger, as determined by agarose gel electrophoresis, were ligated into the plasmid BluScript, Stratagene, La Jolla, California, and transformed into an E. coli DH5α or DHB10 strain. Separately, purified aliquots of the protein were sent to the biotechnology hybπdoma center at the University of Wisconsin, Madison for production of monoclonal antibodies to the proteins. The material that was sent was the HPLC purified fraction containing native bands 1 and 2 which had been denatured at 65 °C, and 20 μg of which was injected into each of four mice. Stable monoclonal antibody-producing hybrido a cell lines were recovered after spleen cells from unimmunized mouse were fused with a stable myeloma cell line. Monoclonal antibodies were recovered from the hybndomas . Separately, polyclonal antibodies were created by taking native agarose gel purified band 1 (see Example 1) protein which was then used to immunize a New Zealand white rabbit. The protein was prepared by excising the band from the native agarose gels, briefly heating the gel pieces to 65°C to melt the agarose, and immediately emulsifying with adjuvant. Freund's complete adjuvant was used for the primary immunizations and Freund's incomplete was used for 3 additional injections at monthly intervals For each injection, approximately 0.2 ml of emulsified band 1, containing 50 to 100 micrograms of protein, was delivered by multiple subcontaneous injections into the back of the rabbit. Serum was obtained 10 days after the final injection and additional bleeds were performed at weekly intervals for 3 weeks. The serum complement was inactivated by heating to 56°C for 15 minutes and then stored at -20°C. The monoclonal and polyclonal antibodies were then used to screen the genomic library for the expression of antigens which could be detected by the epitope. Positive clones were detected on nitrocellulose filter colony lifts. An immunoblot analysis of the positive clones was undertaken. An analysis of the clones as defined by both immunoblot and Southern analysis resulted in the tentative identification of four genomic regions. In the first region was a gene encoding the peptide designated here as TcbA xx . Full DNA sequence of this gene [ tcbA) was obtained. It is set forth as SEQ ID NO: 11. Confirmation that the sequence encodes the internal sequence of SEQ ID NO:l is demonstrated by the presence of SEQ ID NO 1 at ammo acid number 88 -78- SUBSTΓΓUTE SHEET (RULE 26) from the deduced ammo acid sequence created by the open reading frame of SEQ ID NO: 11. This can be confirmed by referring to SEQ ID NO: 12, which is the deduced ammo acid sequence created by SEQ ID NO: 11. The second region of toxin peptides contains the segments referred to above as TcaB x , TcaB lx and TcaC. Following the screening of the library with the polyclonal antisera, this second region of toxm genes was identified by several clones which produced different size proteins, all of which cross-reacted with the polyclonal antibody on an immunoblot and were also found to share DNA homology on a Southern Blot. Sequence comparison revealed that they belonged to the gene complex designated TcaB and TcaC above. Two other regions of antibody toxm clones were also isolated m the polyclonal screen. These regions produced proteins that cross -react with a polyclonal antibody and also shared DNA homology with the regions as determined by Southern blotting. Thus, it appears that the Photorhabdus luminescens extracellular protein genes represent a family of genes which are evolutionarily related To further pursue the concept that there might be evolutionarily related variations m the toxm peptides contained withm this organism, two approaches have been undertaken to examine other strains of Photorhabdus luminescens for the presence of related proteins This was done both by PCR amplification of genomic DNA and by immunoblot analysis using the polyclonal and monoclonal antibodies. The results indicate that related proteins are produced by Photorhabdus . luminescens strains WX-2, WX-3, WX-4, WX-5, WX-6, WX- 7, WX-8, WX-11, WX-12, WX-15 and W-14. Example 11. Part B Sequence and Analysis of tec Toxm Clones Further DNA sequencing was performed on plasmids isolated from E. coli clones described in Example 11, Part A. The nucleotide sequence from the third region of E. coli clones was shown to be three closely linked open reading frames at this genomic locus. This locus was designated tec with the three open reading frames designated tccA SEQ ID NO: 56, tccB SEQ ID NO: 58 and tccC SEQ ID NO: 60 The close linkage between these open reading frames is revealed by examination of SEQ ID NO: 56, which 93 bp separate the stop codon of tccA from the start codon of tccb (bases 2992- 2994 of SEQ ID NO:56), and by examination of SEQ ID NO:58, in which -79- SUBSTΓΓUTE SHEET (RULE 26) 131 bases separate the stop codon of tccB and the tccC (bases 4930- 4932 of SEQ ID NO: 58) . The physical map is presented in Fig. 6B . The deduced ammo acid sequence from the tccA open reading frame indicates that the gene encodes a protein of 105,459 Da. This protein was designated TccA (SEQ ID NO: 57) The first 12 ammo acids of this protein match the N-term al sequence obtained from a 108 kDa protein, SEQ ID NO: 8, previously identified as part of the toxm complex. The deduced amino acid sequence from the tccB open reading frame indicates that this gene encodes a protein of 175,716 Da. This protein was designated TccB (SEQ ID NO: 59) . The first 11 ammo acids of this protein match the N-termmal sequence obtained from a protein with estimated molecular weight of 185 kDa, SEQ ID NO: 7. Similarity analysis revealed that the TccB protein is related to the proteins identified as TcbA SEQ ID NO: 12; 37% similarity and 28% identity, TcdA SEQ ID NO:47, 35% similarity and 28%ιdentιty, and TcaB SEQ ID NO:26; 32% similarity and 26% identity (using the GAP algorithm Wisconsin Package Version 9 0, Genetics Computer Group (GCG) Madison Wisconsin) The deduced ammo acid sequence of tccC indicated that this open reading frame encodes a protein of 111,694 Da and the protein product was designated TccC (SEQ ID NO: 61) Example 12 Characterization of Photorhabdus Strains In order to establish that the collection described herein was comprised of Photorhabdus strains, the strains herein were assessed m terms of recognized microbiological traits that are characteristic of Photorhabdus and which differentiate it from other Enterobacteriaceae and Xenorhabdus spp. (Farmer, J. J 1984. Bergey's Manual of Systemic Bacteriology, Vol 1 pp. 510-511. (ed. Kreig N. R. and Holt, J. G.). Williams & Wilkms, Baltimore,- Akhurst and Boemare, 1988, Boemare et al , 1993). These characteristic traits are as follows- Gram's stain negative rods, organism size of 0.5-2 μm in width and 2-10 μm in length, red/yellow colony pigmentation, presence of crystalline inclusion bodies, presence of catalase, inability to reduce nitrate, presence of biolummescence, ability to take up dye from growth media, positive for protease production, growth-temperature range below 37°C, survival under anaerobic conditions and positively motile. -80- SUBSTΓΓUTE SHEET (RULE 26) (Table 20) . Reference Escheπchia coli , Xenorhabdus and Photorhabdus strains were mcluded in all tests for comparison. The overall results are consistent with all strains being part of the family Enterobacteriaceae and the genus Photorhabdus . A lummometer was used to establish the biolummescence of each strain and provide a quantitative and relative measurement of light production. For measurement of relative light emitting units, the broths from each strain (cells and media) were measured at three time intervals after inoculation in liquid culture (6, 12, and 24 hr) and compared to background luminosity (unmoculated media and water) . Prior to measuring light emission from the various broths, cell density was established by measuring light absorbance (560 nM) in a Gilford Systems (Oberlm, OH) spectrophotometer using a sipper cell. Appropriate dilutions were then made (to normalize optical density to 1.0 unit) before measuring luminosity Aliquots of the diluted broths were then placed into cuvettes (300 μl each) and read in a Bio-Orbit 1251 Lummometer (Bio-Orbit Oy, Twiku, Finland) . The integration period for each sample was 45 seconds. The samples were continuously mixed (spun in baffled cuvettes) while being read to provide oxygen availability. A positive test was determined as being > 5-fold background luminescence (about 5-10 units) . In addition, colony luminosity was detected with photographic film overlays and visually, after adaptation in a darkroom. The Gram's staining characteristics of each strain were established with a commercial Gram's stain kit (BBL, Cockeysville, MD) used m conjunction with Gram's stain control slides (Fisher Scientific, Pittsburgh, PA) . Microscopic evaluation was then performed using a Zeiss microscope (Carl Zeiss, Germany) 100X oil immersion objective lens (with 10X ocular and 2X body magnification) . Microscopic examination of individual strains for organism size, cellular description and inclusion bodies (the latter after logarithmic growth) was performed using wet mount slides (10X ocular, 2X body and 40X objective magnification) with oil immersion and phase contrast microscopy with a micrometer (Akhurst, R.J. and Boemare, N.E. 1990. Entomopathogenic Nematodes in Biological Control (ed. Gaugler, R. and Kaya, H ). pp. 75-90. CRC Press, Boca Raton, USA.; Baghdiguian S., Boyer-Giglio M.H., Thaler, J.O , Bonnot G., Boemare N. 1993 Biol. Cell 79, 177-185.). Colony pigmentation was observed after -81 - SUBSTΓΓUTE SHEET (RULE 2S) inoculation on Bacto nutrient agar, .(Difco Laboratories, Detroit, MI) prepared as per label instructions. Incubation occurred at 28 °C and descriptions were produced after 5-7 days. To test for the presence of the enzyme catalase, a colony of the test organism was removed on a small plug from a nutrient agar plate and placed into the bottom of a glass test tube. One ml of a household hydrogen peroxide solution was gently added down the side of the tube. A positive reaction was recorded when bubbles of gas (presumptive oxygen) appeared immediately or with 5 seconds. Controls of unmoculated nutrient agar and hydrogen peroxide solution were also examined. To test for nitrate reduction, each culture was inoculated into 10 ml of Bacto Nitrate Broth (Difco Laboratories, Detroit, MI). After 24 hours incubation at 28°C, nitrite production was tested by the addition of two drops of sulfanilic acid reagent and two drops of alpha-naphthylamme reagent (see Difco Manual, 10th edition, Difco Laboratories, Detroit, MI, 1984) . The generation of a distinct pink or red color indicates the formation of nitrite from nitrate The ability of each strain to uptake dye from growth media was tested with Bacto MacConkey agar containing the dye neutral red; Bacto Tergιtol-7 agar containing the dye bromothymol blue and Bacto EMB Agar containing the dye eosm-Y (agars from Difco Laboratories, Detroit, MI, all prepared according to label instructions) After inoculation on these media, dye uptake was recorded after incubation at 28°C for 5 days. Growth on these latter media is characteristic for members of the family En t erobactena ceae Motility of each strain was tested using a solution of Bacto Motility Test Medium (Difco Laboratories, Detroit, MI) prepared as per label instructions. A butt-stab inoculation was performed with each strain and motility was judged macroscopically by a diffuse zone of growth spreading from the line of inoculum. In many cases, motility was also observed microscopically from liquid culture under wet mount slides. Biochemical nutrient evaluation for each strain was performed using BBL Enterotube II (Benton, Dickinson, Germany) . Product instructions were followed with the exception that incubation was carried out at 28°C for 5 days Results were consistent with previously cited reports for Photorhabdus . The production of protease was tested by observing hydrolysis of gelatin using Bacto gelatin (Difco Laboratories, Detroit, MI) plates made as per label instructions. Cultures were inoculated and the plates were incubated at 28°C for 5 days. To assess growth at different temperatures, agar plates [2% proteose peptone #3 with two percent Bacto-Agar (Difco, Detroit, MI) in deionized water] were streaked from a common source of inoculum. Plates were sealed with Nesco" film and incubated at 20, 28 and 37°C for up to three weeks. Plates showing no growth at 37°C showed no cell viability after transfer to a 28°C incubator for one week. Oxygen requirements for Photorhabdus strains were tested m the following manner. A butt -stab inoculation into fluid thioglycolate broth medium (Difco, Detroit, MI) was made. The tubes were incubated at room temperature for one week and cultures were then examined for type and extent of growth. The indicator resazurm demonstrates the level of medium oxidation or the aerobiosis zone (Difco Manual, 10th edition, Difco Laboratories, Detroit, MI). Growth zone results obtained for the Photorhabdus strains tested were consistent with those of a facultative anaerobic microorganism. -83- SUBSTΓΠJTE SHEET (RULE 26) Table 19 Taxonomic Traits of Photorhabdus Strains C=Bιolummescence, D=Cell form, E=Motιlιty, F=Nιtrate reduction, G=Presence of catalase, H=Gelatm hydrolysis, I=Dye uptake, J=Pιgmentatιon, K=Growth on EMB agar, L=Growth on MacConkey agar, M=Growth on Tergιtol-7 agar, N=Facultatιve anaerobe, 0=Growth at 20°C, P=Growth at 28°C, Q=Growth at 37°C, t - +/- = positive or negative for trait, rd=rod, S=sιzed withm Genus descriptors, RO=red-orange, LR = light red, R= red, 0= orange, Y= yellow, T= tan, LY= light yellow, YT= yellow tan, and L0= light orange. Cellular fatty acid analysis is a recognized tool for bacterial characterization at the genus and species level (Tornabene, T. G. 1985. Lipid Analysis and the Relationship to Chemotaxono y in Methods in Microbiology. Vol. 18, 209-234.; Goodfellow, M. and O'Donnell, A. G. 1993. Roots of Bacterial Systematics in Handbook of New Bacterial Systematics (ed. Goodfellow, M. & O'Donnell, A. G.) pp. 3-54. London. Academic Press Ltd.), these references are incorporated herein by reference, and were used to confirm that our collection was related at the genus level. Cultures were shipped to an external, contract laboratory for fatty acid methyl ester analysis (FAME) using a Microbial ID (MIDI, Newark, DE, USA) Microbial Identification System (MIS) The MIS system consists of a Hewlett Packard HP5890A gas chromatograph with a 25mm x 0.2mm 5% methylphenyl silicone fused silica capillary column. Hydrogen is used as the carrier gas and a flame-ionization detector functions in conjunction with an automatic sampler, integrator and computer. The computer compares the sample fatty acid methyl esters to a microbial fatty acid library and against a calibration mix of known fatty acids. As selected by the contract laboratory, strains were grown for 24 hours at 28°C on trypticase soy agar prior to analysis. Extraction of samples was performed by the contract lab as per standard FAME methodology. There was no direct identification of the strains to any luminescent bacterial group other than Photorhabdus. When the cluster analysis was performed, which compares the fatty acid profiles of a group of isolates, the strain fatty acid profiles were related at the genus level . The evolutionary diversity of the Photorhabdus strains in our collection was measured by analysis of PCR (Polymerase Cham Reaction) mediated genomic fingerprinting using genomic DNA from each strain. This technique is based on families of repetitive DNA sequences present throughout the genome of diverse bacterial species (reviewed by Versalovic, J., Schneider, M., DE Brui n, F. J. and Lupski, J. R. 1994. Methods Mol. Cell. Biol., 5, 25-40.). Three of these, repetitive extragenic palmdromic sequence (REP), enterobacterial repetitive mtergenic consensus (ERIC) and the BOX element are thought to play an important role in the organization of the bacterial genome. Genomic organization is believed to be shaped by selection and the differential dispersion of these elements withm the genome of closely related bacterial strains can be used to discriminate these strains (e.g., Louws, F J., Fulbπght, D. W., Stephens, C. T. and DE Bruijn, F. J. 1994. Appl. Environ. Micro 60, 2286-2295) . Rep-PCR utilizes oligonucleotide primers complementary to these repetitive sequences to amplify the variably sized DNA fragments lying between them. The resulting products are separated by electrophoresis to establish the DNA "fingerprint" for each strain. To isolate genomic DNA from our strains, cell pellets were resuspended TE buffer (10 mM Tris-HCl, 1 mM EDTA, pH 8 0) to a -85- SUBSTΓΓUTE SHEET (RULE 26) final volume of 10 ml and 12 ml of 5. M NaCl was then added. This mixture was centrifuged 20 mm. at 15,000 x g. The resulting pellet was resuspended m 5.7 ml of TE and 300 μl of 10% SDS and 60 μl 20 mg/ml protemase K (Gibco BRL Products, Grand Island, NY) were added. This mixture was incubated at 37 °C for 1 hr, approximately 10 mg of lysozy e was then added and the mixture was incubated for an additional 45 mm. One milliliter of 5M NaCl and 800 μl of CTAB/NaCl solution (10% w/v CTAB, 0.7 M NaCl) were then added and the mixture was incubated 10 mm. at 65°C, gently agitated, then incubated and agitated for an additional 20 mm. to aid clearing of the cellular material. An equal volume of chlorofor /isoamyl alcohol solution (24:1, v/v) was added, mixed gently then centrifuged. Two extractions were then performed with an equal volume of phenol/chloroform/isoamyl alcohol (50:49:1). Genomic DNA was precipitated with 0.6 volume of isopropanol. Precipitated DNA was removed with a glass rod, washed twice with 70% ethanol, dried and dissolved in 2 ml of STE (10 mM Tris-HCl pH8.0, 10 mM NaCl, 1 mM EDTA) . The DNA was then quantitated by optical density at 260 nm. To perform rep-PCR analysis of Photorhabdus genomic DNA the following primers were used, REP1R-I; 5' -IIIICGICGICATCIGGC-3 ' and REP2-I; 5 ' -ICGICTTATCIGGCCTAC-3 ' PCR was performed using the following 25μl reaction: 7.75 μl H2O, 2.5 μl 10X LA buffer (PanVera Corp., Madison, WI), 16 μl dNTP mix (2.5 mM each), 1 μl of each primer at 50 pM/μl, 1 μl DMSO, 1.5 μl genomic DNA (concentrations ranged from 0.075-0.480 μg/μl) and 0.25 μl TaKaRa EX Taq (PanVera Corp., Madison, WI) The PCR amplification was performed in a Perkin Elmer DNA Thermal Cycler (Norwalk, CT) using the following conditions: 95°C/7 mm. then 35 cycles of; 94°C/1 mm.,44°C/l mm., 65°C/8 mm., followed by 15 mm. at 65°C. After cycling, the 25 μl reaction was added to 5 μl of 6X gel loading buffer (0.25% bromophenol blue, 40% w/v sucrose in H2O) . A 15x20cm 1%-agarose gel was then run in TBE buffer (0.09 M Tris-borate, 0.002 M EDTA) using 8 μl of each reaction. The gel was run for approximately 16 hours at 45v. Gels were then stained in 20 μg/ml ethidium bromide for 1 hour and destamed in TBE buffer for approximately 3 hours. Polaroid photographs of the gels were then taken under UV illumination. The presence or absence of bands at specific sizes for each strain was scored from the photographs and entered as a similarity -86- SUBSTΓΓUTE SHEET (RULE 26) matrix in the numerical taxonomy software program, NTSYS-pc (Exeter Software, Setauket, NY) . Controls of E. coli strain HB101 and Xanthomonas oryzae pv. oryzae assayed at the same time produced PCR "fingerprints" corresponding to published reports (Versalovic, J., Koeuth, T. and Lupski , J. R. 1991. Nucleic Acids Res. 19, 6823- 6831; Vera Cruz, C. M., Halda-Alija, L., Louws, F., Skinner, D. Z., George, M. L., Nelson, R. J., DE Bruijn, F. J., Rice, C. and Leach, J. E. 1995. Int.

Phytopathology (m press, respectively) . The data from Photorhabdus strains were then analyzed with a series of programs withm NTSYS-pc; SIMQUAL (Similarity for Qualitative data) to generate a matrix of similarity coefficients (using the Jaccard coefficient) and SAHN (Sequential, Agglomerative, Heirarchical and Nested) clustering [using the UPGMA (Unweighted Pair-Group Method with Arithmetic Averages) method] which groups related strains and can be expressed as a phenogram (Fig. 5) . The COPH (cophenetic values) and MXCOMP (matrix comparison) programs were used to generate a cophenetic value matrix and compare the correlation between this and the original matrix upon which the clustering was based. A resulting normalized Mantel statistic (r) was generated which is a measure of the goodness of fit for a cluster analysis (r=0.8-0.9 represents a very good fit) . In our case r = 0.919 Therefore, our collection is comprised of a diverse group of easily distinguishable strains representative of the Photorhabdus genus. Example 13 Insecticidal Utility of Toxm(s) Produced by Various Photorhabdus Strains Initial "seed" cultures of the various Photorhabdus strains were produced by inoculating 175 ml of 2% Proteose Peptone #3 (PP3) (Difco Laboratories, Detroit, MI) liquid media with a primary variant subclone in a 500 ml tribaffled flask with a Delong neck, covered with a Kaput. Inoculum for each seed culture was derived from oil-overlay agar slant cultures or plate cultures. After inoculation, these flasks were incubated for 16 hrs at 28°C on a rotary shaker at 150 rpm. These seed cultures were then used as -87- SUBSTΓΓUTE SHEET (RULE 26) uniform inoculum sources for a given fermentation of each strain. Additionally, overlaying the post-log seed culture with sterile mineral oil, adding a sterile magnetic stir bar for future resuspension and storing the culture the dark, at room temperature provided long-term preservation of inoculum in a toxin- competent state. The production broths were inoculated by adding 1% of the actively growing seed culture to fresh 2% PP3 media (e.g., 1.75 ml per 175 ml fresh media). Production of broths occurred m either 500 ml tribaffled flasks (see above) , or 2800 ml baffled, convex bottom flasks (500 ml volume) covered by a silicon foam closure. Production flasks were incubated for 24-48 hrs under the above mentioned conditions. Following incubation, the broths were dispensed into sterile 1 L polyethylene bottles, spun at 2600 x g for 1 hr at 10°C and decanted from the cell and debris pellet The liquid broth was then vacuum filtered through Whatman GF/D (2.7 μM retention) and GF/B (1.0 μM retention) glass filters to remove debris. Further broth clarification was achieved with a tangential flow microflltration device (Pall Filtron, Northborough, MA) using a 0.5 μM open-channel filter. When necessary, additional clarification could be obtained by chilling the broth (to 4°C) and centrifugmg for several hours at 2600 x g. Following these procedures, the broth was filter sterilized using a 0.2 μM nitrocellulose membrane filter. Sterile broths were then used directly for biological assay, biochemical analysis or concentrated (up to 15-fold) using a 10,000 MW cut-off, M12 ultra-flltration device (Amicon, Beverly MA) or centrifugal concentrators (Millipore, Bedford, MA and Pall Filtron, Northborough, MA) with a 10,000 MW pore size. In the case of centrifugal concentrators, the broth was spun at 2000 x g for approximately 2 hr. The 10,000 MW permeate was added to the corresponding retentate to achieve the desired concentration of components greater than 10,000 MW Heat inactivation of processed broth samples was acheived by heating the samples at 100°C in a sand-filled heat block for 10 minutes The broth (s) and toxm complex (es) from different Photorhabdus strains are useful for reducing populations of insects and were used in a method of inhibiting an insect population which comprises applying to a locus of the insect an effective insect inactivating amount of the active described. A demonstration of the breadth of msecticidal activity ODserved from broths of a selected group of Photorhabdus strains fermented as described above is shown in Table 20. It is possible that additional msecticidal activities could be detected with these strains through increased concentration of the broth or by employing different fermentation methods. Consistent with the activity being associated with a protein, the msecticidal activity of all strains tested was heat labile (see above ) Culture broth (s) from diverse Photorhabdus strains show differential msecticidal activity (mortality and/or growth inhibition, reduced adult emergence) against a number of insects. More specifically, the activity is seen against corn rootworm larvae and boll weevil larvae which are members of the insect order Coleoptera . Other members of the Coleoptera include wireworms, pollen beetles, flea beetles, seed beetles and Colorado potato beetle Activity is also observed against aster leafhopper and corn plant hopper, which are members of the order Homoptera Other members of the Homoptera include planthoppers , pear psylla, apple sucker, scale insects, whiteflies, spittle bugs as well as numerous host specific aphid species The broths and purified toxm comple (es) are also active against tobacco budworm, tobacco hornworm and European corn borer which are members of the order Lepidoptera Other typical members of this order are beet armyworm, cabbage looper, black cutworm, corn earworm, codling moth, clothes moth, Indian mealmoth, leaf rollers, cabbage worm, cotton bollworm, bagworm, Eastern tent caterpillar, sod webworm and fall armyworm Activity is also seen against fruitfly and mosquito larvae which are members of the order Diptera . Other members of the order Diptera are, pea midge, carrot fly, cabbage root fly, turnip root fly, onion fly, crane fly and house fly and various mosquito species. Activity with broth (s) and toxm complex (es) is also seen against two-spotted spider mite which is a member of the order Acarina which includes strawberry spider mites, broad mites, citrus red mite, European red mite, pear rust mite and tomato russet mite Activity against corn rootworm larvae was tested as follows Photorhabdus culture broth(s) (0-15 fold concentrated, filter sterilized), 2% Proteose Peptone #3, purified toxm complex(es), 10 mM sodium phosphate buffer , pH 7 0 were applied directly to the surface (about 1 5 cm 2 ) of artificial diet (Rose, R I and McCabe , -89- SUBSTΓΠJTE SHEET (RULE 26) J. M. (1973) . J. Econ. Ento ol . 66, .(398-400) in 40 μl aliquots. Tox complex was diluted in 10 mM sodium phosphate buffer, pH 7.0 The diet plates were allowed to air-dry in a sterile flow-hood and the wells were infested with single, neonate Diabrotica uπdecunpuπctata howardi (Southern corn rootworm, SCR) hatched from surface sterilized eggs. The plates were sealed, placed m a humidified growth chamber and maintained at 27°C for the appropriate period (3-5 days) . Mortality and larval weight determinations were then scored. Generally, 16 insects per treatment were used in all studies. Control mortality was generally less than 5%. Activity against boll weevil (Antho onas grandis) was tested as follows. Concentrated (1-10 fold) Photorhabdus broths, control medium (2% Proteose Peptone #3), purified toxm complex(es) [0.23 mg/ml] or 10 mM sodium phosphate buffer, pH 7.0 were applied 60 μl aliquots to the surface of 0.35 g of artificial diet (Stoneville Yellow lepidopteran diet) and allowed to dry. A single, 12-24 hr boll weevil larva was placed on the diet, and the wells were sealed and held at 25°C, 50% RH for 5 days. Mortality and larval weights were then assessed. Control mortality ranged between 0-13% Activity against mosquito larvae was tested as follows The assay was conducted m a 96-well microtiter plate. Each well contained 200 μl of aqueous solution (10-fold concentrated Photorhabdus culture broth(s) , control medium (2% Proteose Peptone #3), 10 mM sodium phosphate buffer, toxin complex(es) @ 0.23 mg/ml or H2O) and approximately 20, 1-day old larvae [Aedes aegypti ) . There were 6 wells per treatment. The results were read at 3-4 days after infestation. Control mortality was between 0-20%. Activity against fruitflies was tested as follows. Purchased Drosophila melanogaster medium was prepared using 50% dry medium and a 50% liquid of either water, control medium (2% Proteose Peptone #3), 10-fold concentrated Photorhabdus culture broth(s), purified tox complex (es) [0.23 mg/ml] or 10 mM sodium phosphate buffer , pH 7.0. This was accomplished by placing 4.0 ml of dry medium in each of 3 rearing vials per treatment and adding 4.0 ml of the appropriate liquid. Ten late instar Drosophila melanogaster maggots were then added to each 25 ml vial. The vials were held on a laboratory bench, at room temperature, under fluorescent ceiling lights Pupal or adult counts were made after 15 days of exposure. -90- SUBSTTTUTE SHEET (RULE 26) Adult emergence as compared to water, and control medium (0-16% reduction) . Activity against aster leafhopper adults [Macrosteles severini ) and corn planthopper nymphs [ Peregrinus aidis) was tested with an ingestion assay designed to allow ingestion of the active without other external contact. The reservoir for the active/ "food" solution is made by making 2 holes in the center of the bottom portion of a 35X10 mm Petri dish. A 2 inch Parafilm M square is placed across the top of the dish and secured with an "0" ring. A 1 oz. plastic cup is then infested with approximately 7 hoppers and the reservoir is placed on top of the cup, Parafilm down. The test solution is then added to the reservoir through the holes. In tests using 10 -fold concentrated Photorhabdus culture broth (s) , the broth and control medium (2% Proteose Peptone #3) were dialyzed against 10 mM sodium phosphate buffer, pH 7.0 and sucrose (to 5%) was added to the resulting solution to reduce control mortality. Purified toxm complex(es) [0.23 mg/ml] or 10 mM sodium phosphate buffer, pH 7.0 was also tested. Mortality is reported at day 3. The assay was held in an incubator at 28°C, 70% RH with a 16/8 photoperiod. The assays were graded for mortality at 72 hours. Control mortality was less than 6%. Activity against lepidopteran larvae was tested as follows. Concentrated (10-fold) Photorhabdus culture broth(s), control medium (2% Proteose Peptone #3), purified toxin co plex(es) [0.23 mg/ml] or 10 mM sodium phosphate buffer, pH 7.0 were applied directly to the surface (about 1.5 cm 2 ) of standard artificial lepidopteran diet (Stoneville Yellow diet) in 40 μl aliquots. The diet plates were allowed to air-dry in a sterile flow-hood and each well was infested with a single, neonate larva. European corn borer [ Ostrinia nubilalis) and tobacco hornworm [Manduca sexta) eggs were obtained from commercial sources and hatched in-house, whereas tobacco budworm [ Heliothis virescens) larvae were supplied internally. Following infestation with larvae, the diet plates were sealed, placed m a humidified growth chamber and maintained in the dark at 27°C for the appropriate period. Mortality and weight determinations were scored at day 5. Generally, 16 insects per treatment were used in all studies. Control mortality generally ranged from about 4 to about 12.5% for control medium and was less than 10% for phosphate buffer. -91- SUBSTΪTUTE SHEET (RULE 26) Activity against two-spotted spider mite [ Tetranychuε urticae) was determined as follows. Young squash plants were trimmed to a single cotyledon and sprayed to run-off with 10-fold concentrated broth(s), control medium (2% Proteose Peptone #3), purified toxin complex (es) , 10 mM sodium phosphate buffer, pH 7.0. After drying, the plants were infested with a mixed population of spider mites and held at lab temperature and humidity for 72 hr. Live mites were then counted to determine levels of control . -92- SUBSTΓΠJTE SHEET (RULE 26) Table . 20 Observed Insecticidal Spectrum of Broths from Different Photorhabdus Strains Photorhabdus strain sensitive* Insect species WX-l 3**, 4, 5, 6, 7, WX-2 2, 4 WX-3 1, 4 WX-4 1, 4 WX-5 4 WX-6 4 WX-7 3, 4, 5, 6, 7, WX-8 1, 2, 4 WX-9 1 WX-10 4 WX-11 1 4 WX-12 2, 4, 5 5, 6, 7, i WX-14 1 4 WX-15 4 W30 5, NC-1 3, 7, 8, 9 WIR 5, HP88 4, Hb 5, 7, 8 Hm 3, 4, 5, 7, 8 H9 3, 4, 5, 6, 7, 8 W-14 3, 4, 5, 6, 7, 8, 10 ATCC 43948 ATCC 43949 ATCC 43950 ATCC 43951 ATCC 43952 * > 25% mortality and/or growth inhibition vs. control ** 1; Tobacco budworm, 2; European corn borer, 3 ; Tobacco hornworm, 4; Southern corn rootworm, 5; Boll weevil, 6; Mosquito, 7; Fruit Fly, 8 ,- Aster Leafhopper, 9; Corn planthopper, 10; Two-spotted spider mite. •93- SUBSTΓΓUTE SHEET (RULE 26) Example. 14 Non W-14 Photprh,flbdug Strains; Purification. Characterization and Activity Spectrum Pur-i£.ιcatι.gn The protocol, as follows, is similar to that developed for the purification of W-14 and was established based on purifying those fractions having the most activity against Southern corn root worm (SCR), as determined bioassays (see Example 13) Typically, 4- 20 L of broth that had been filtered, as described in Example 13, were received and concentrated using an Amicon spiral ultra filtration cartridge Type SIYIOO attached to an Amicon M-12 filtration device. The retentate contained native proteins consisting of molecular sizes greater than 100 kDa, whereas the flow through material contained native proteins less than 100 kDa m size. The majority of the activity against SCR was contained in the 100 kDa retentate. The retentate was then continually diafiltered with 10 mM sodium phosphate (pH = 7.0) until the filtrate reached an A28O 0.100. Unless otherwise stated, all procedures from this point were performed in buffer as defined by 10 mM sodium phosphate (pH 7.0) . The retentate was then concentrated to a final volume of approximately 0 20 L and filtered using a 0.45 mm Nalgene™ Filterware sterile filtration unit. The filtered material was loaded at 7.5 ml/mm onto a Pharmacia HR16/10 column which had been packed with PerSeptive Biosystem Poros ® 50 HQ strong anion exchange matrix equilibrated in buffer using a PerSeptive Biosystem Sprint ® HPLC system After loading, the column was washed with buffer until an A28O < 0-100 was achieved. Proteins were then eluted from the column at 2.5 ml/mm using buffer with 0.4 M NaCl for 20 mm for a total volume of 50 ml. The column was then washed using buffer with 1.0 M NaCl at the same flow rate for an additional 20 min (final volume = 50 ml) Proteins eluted with 0.4 M and 1.0 M NaCl were placed in separate dialysis bags (Spectra/Por ® Membrane MWCO. 2,000) and allowed to dialyze overnight at 4° C in 12 L buffer The majority of the activity against SCR was contained m the 0 4 M fraction The 0.4 M fraction was further purified by application of 20 ml to a Pharmacia XK 26/100 column that had been prepacked with Sepharose CL4B (Pharmacia) using a flow rate of 0 75 ml/mm Fractions were -94- SUBSTΠΓUTE SHEET (RULE 26) pooled based on A28O peak profile and concentrated to a final volume of 0.75 ml using a Millipore Ultrafree ® - 15 centrifugal filter device Biomax-50K NMWL membrane. Protein concentrations were determined using a Biorad Protein Assay Kit with bovine gamma globulin as a standard. Characterization The native molecular weight of the SCR toxin complex was determined using a Pharmacia HR 16/50 that had been prepacked with Sepharose CL4B in buffer. The column was then calibrated using proteins of known molecular size thereby allowing for calculation of the toxin approximate native molecular size. As shown in Table 21, the molecular size of the toxin complex ranged from 777 kDa with strain Hb to 1,900 kDa with strain WX-14. The yield of toxin complex also varied, from strain WX-12 producing 0.8 mg/L to strain Hb, which produced 7.0 mg/L. Proteins found in the tox complex were examined for individual polypeptide size using SDS-PAGE analysis. Typically, 20 mg protein of the toxin complex from each strain was loaded onto a 2-15% polyacrylamide gel (Integrated Separation Systems) and electrophoresed at 20 mA in Biorad SDS-PAGE buffer. After completion of electrophoresis, the gels were stained overnight in Biorad Coomassie blue R-250 (0.2% in methanol: acetic acid: water; 40:10:40 v/v/v) . Subsequently, gels were destained in methanol .-acetic acid: water; 40:10:40 (v/v/v). The gels were then rinsed with water for 15 min and scanned using a Molecular Dynamics Personal Laser Densitometer ® . Lanes were quantitated and molecular sizes were calculated as compared to Biorad high molecular weight standards, which ranged from 200-45 kDa. Sizes of the individual polypeptides comprising the SCR toxin complex from each strain are listed in Table 22. The sizes of the individual polypeptides ranged from 230 kDa with strain WX-1 to a size of 16 kDa, as seen with strain WX-7. Every strain, with the exception of strain Hb, had polypeptides comprising the toxin complex that were in the 160-230 kDa range, the 100-160 kDa range, and the 50-80 kDa range. These data indicate that the toxm complex may vary in peptide composition and components from strain to strain, however, in all cases the toxin attributes appears to consist of a large, oligomeric protein complex. -95- SUBSTTRJTE SHEET (RULE 26) Table 21 Characterization of a Toxm Complex from Non W-14 Photorhabdus Strains Activity Spectrum As shown m Table 23, the toxm complexes purified from strains Hm and H9 were tested for activity against a variety of insects, with the toxm complex from strain W-14 for comparison. The assays were performed as described in Example 13. The toxm complex from all three strains exhibited activity against tobacco bud worm, European corn borer, Southern corn root worm, and aster leafhopper. Furthermore, the toxm complex from strains Hm and W- 14 also exhibited activity against two-spotted spider mite In addition, the toxin complex from W-14 exhibited activity against mosquito larvae These data indicate that the toxm complex, while having similarities in activities between certain orders of insects, can also exhibit differential activities against other orders of insects . -96- SUBSTΪTUTE SHEET (RULE 26) Table 22 The Approx mate Sizes (in kDa) of Peptides in a Purified Tojcin Complex From Non W-14 Photorhabdus H9 Hb Hm HP 88 NC-1 WIR WX-1 WX-2 WX-7 WX-12 WX-14 W-14 170 230 200 200 180 160 190 170 180 160 120 170 150 110 140 110 160 120 87 139 89 110 110 75 130 79 98 82 43 110 I 74 76 64 33 92 62 58 37 28 87 51 53 30 26 80 40 41 23 73 39 35 22 59 37 31 21 56 33 28 19 51 30 24 18 37 28 22 16 33 27 32 25 26 23 Table 23 Observed Insecticidal Spectrum of a Purified Toxin Complex from Photorhabdus Strains Photorhabdus Strain sensitive* Insect Species Hm Toxin Complex 1**, 2, 3, 5, 6, 7, 8 H9 Toxin Complex 1, 2, 3, 6, 7, 8 W-14 Tox Complex 1, 2, 3, 4, 5, 6, 7, f * = > 25% mortality or growth inhibition * = > 25% mortality or growth inhibition ** = 1, Tobacco bud worm; 2, European corn borer,- 3, Southern corn root worm; 4, Mosquito; 5, Two-spotted spider mite; 6, Aster Leafhopper; 7, Fruit Fly; 8, Boll Weevil Example 15 Sub-Fractionation of Photorhabdus Protein Tox Complex The Photorhabdus protein tox complex was isolated as described in Example 14. Next, about 10 mg toxm was applied to a MonoQ 5/5 column equilibrated with 20 mM Tris-HCl, pH 7.0 at a flow rate of lml/min. The column was washed with 20 mM Tris-HCl, pH 7.0 until the optical density at 280 nm returned to baseline absorbance . The proteins bound to the column were eluted with a linear gradient of 0 to 1.0 M NaCl m 20 mM Tris-HCl, pH 7.0 at 1 ml/min for 30 min. One ml fractions were collected and subjected to Southern corn rootworm (SCR) bioassay (see Example 13). Peaks of activity were determined by a series of dilutions of each fraction in SCR bioassays. Two activity peaks against SCR were observed and were named A (eluted at about 0.2-0.3 M NaCl) and B (eluted at 0.3-0.4 M NaCl) . Activity peaks A and B were pooled separately and both peaks were further purified using a 3 -step procedure described below. Solid (NH-j.}2Sθ4 was added to the above protein fraction to a final concentration of 1.7 M. Proteins were then applied to a phenyl-Superose 5/5 column equilibrated with 1.7 M (NH4)2S04 in 50 mM potassium phosphate buffer, pH 7 at 1 ml/mm. Proteins bound to the column were eluted with a linear gradient of 1.7 M (NH4)2Sθ4, 0% ethylene glycol, 50 mM potassium phosphate, pH 7.0 to 25% ethylene glycol, 25 mM potassium phosphate, pH 7.0 (no (NH4)2≤θ4) at 0.5 ml/mm. Fractions were dialyzed overnight against 10 mM sodium phosphate buffer, pH 7.0. Activities m each fraction against SCR were determined by bioassay. -98- SUBSTΓΓUTE SHEET (RULE 26) The fractions with the highest activity were pooled and applied to a MonoQ 5/5 column which was equilibrated with 20 mM Tris-HCl, pH 7 0 at 1 ml/mm. The proteins bound to the column were eluted at 1 ml/mm by a linear gradient of 0 to IM NaCl in 20 For the final step of purification, the most active fractions above (determined by SCR bioassay) were pooled and subjected to a second phenyl-Superose 5/5/ column. Solid (NH4)2S04 was added to a final concentration of 1.7 M. The solution was then loaded onto the column equilibrated with 1.7 M (NH4)2S04 in 50 mM potassium phosphate buffer, pH 7 at 1ml/mm. Proteins bound to the column were eluted with a linear gradient of 1.7 M ( H4)2S04, 50 mM potassium phosphate, pH 7.0 to 10 mM potassium phosphate, pH 7.0 at 0.5 ml/min. Fractions were dialyzed overnight against 10 mM sodium phosphate buffer, pH 7.0. Activities in each fraction against SCR were determined by bioassay The final purified protein by the above 3 -step procedure from peak A was named toxm A and the final purified protein from peak B was named toxm B . Characterization and Ammo Acid Sequencing of Tox A and Toxm B In SDS-PAGE, both toxm A and toxin B contained two major (> 90% of total Commassie stained protein) peptides: 192 kDa (named Al and Bl, respectively) and 58 kDa (named A2 and B2 , respectively) Both toxm A and toxm B revealed only one major band in native PAGE, indicating Al and A2 were subunits of one protein complex, and Bl and B2 were subunits of one protein complex Further, the native molecular weight of both toxm A and tox B were determined to be 860 kDa by gel filtration chromatography. The relative molar concentrations of Al to A2 was judged to be a 1 to 1 equivalence as determined by densiometric analysis of SDS-PAGE gels. Similarly, Bl and B2 peptides were present at the same molar concentration. Tox A and toxm B were electrophoresed m 10% SDS-PAGE and transblotted to PVDF membranes. Blots were sent for ammo acid analysis and N-termmal ammo acid sequencing at Harvard MicroChe and Cambridge ProChem, respectively The N-termmal amino sequence of Bl was determined to be identical to SEQ ID N0:1, the TcbA xl region of the tcbA gene (SEQ ID NO: 12, position 87 to 99) A unique N-termmal sequence was obtained for peptide B2 (SEQ ID NO -.40) The N-termmal ammo acid sequence of peptide B2 was identical to the TcbA xll region of the derived ammo acid sequence -99- SUBSTΓΓUTE SHEET (RULE 26) for the tcbA gene (SEQ ID NO: 12, position 1935 to 1945) . Therefore, the B toxm contained predominantly two peptides, TcbAn and Tc Ain, that were observed to be derived from the same gene product, TcbA. The N-terminal sequence of A2 (SEQ ID NO: 41) was unique in comparison to the TcbA llx peptide and other peptides. The A2 peptide was denoted TcdA nι (see Example 17) . SEQ ID NO: 6 was determined to be a mixture of amino acid sequences SEQ ID NO: 40 and 41. Peptides Al and A2 were further subjected to internal am o acid sequencing. For internal ammo acid sequencing, 10 μg of tox A was electrophoresized in 10% SDS-PAGE and transblotted to PVDF membrane. After the blot was stained with amido black, peptides Al and A2 , denoted TcdA 1;L and TcdA , respectively, were excised from the blot and sent to Harvard MicroChem and Cambridge ProChem. Peptides were subjected to trypsin digestion followed by HPLC chromatography to separate individual peptides. N-termmal ammo acid analysis was performed on selected tryptic peptide fragments . Two internal am o acid sequences of peptide Al (TcdAn-PK71, SEQ ID NO.-38 and TcdA xl -PK44, SEQ ID NO: 39) were found to have significant homologies with deduced ammo acid sequences of the TcbAn region of the tcbA gene (SEQ ID NO: 12) . Similarly, the N-termmal sequence (SEQ ID NO: 41) and two internal sequences of peptides A2 (TcdA 1;ιl -PK57, SEQ ID NO:42 and Tc A lu - PK20, SEQ ID NO.43) also showed significant homology with deduced ammo acid sequences of TcbA nι region of the tcbA gene (SEQ ID NO: 12) . In summary of above results, the toxm complex has at least two ~ actιve protein toxm complexes against SCR; toxin A and tox B. Tox A and toxm B are similar in their nat£ve ~ and subunits molecular weight, however, their peptide compositions are different. Tox A contained peptides TcdA lx and TcdA lu as the major peptides and the toxm B contains TcbAn and TcbAn I as the major peptides. Purification and Characterization of Toxm C. Tea Peptides The Photorhabdus protein toxm complex was isolated as described above. Next, about 50 mg toxm was applied to a MonoQ 10/10 column equilibrated with 20 mM Tris-HCl, pH 7 0 at a flow rate of 2 ml/mm. The column was washed with 20 mM Tris-HCl, pH7.0 -100- SUBSTΓΓUTE SHEET (RULE 26) until the optical density at 280 nm returned to baseline level. The proteins bound to the column were eluted with a linear gradient of 0 to IM NaCl m 20 mM Tris-HCl, pH 7.0 at 2 ml/mm for 60 mm. 2 ml fractions were collected and subjected to Western analysis using pAb TcaBn-syn antibody (see Example 21) as the primary antibody. Fractions reacted with pAb TcaBn-syn antibody were combined and solid (NH4)2Sθ4 was added to a final concentration of 1.7 M. Proteins were then applied to a phenyl-Superose 10/10 column equilibrated with 1.7 M (NH4)2S04 in 50 mM potassium phosphate buffer, pH 7 at lml/mm. Proteins bound to the column were eluted with a linear gradient of 1.7 M (NH4)2Sθ4, 50 mM potassium phosphate, pH 7.0 to 10 mM potassium phosphate, pH 7.0 at 1 ml/mm for 120 mm. 2ml Fractions were collected, dialyzed overnight against 10 mM sodium phosphate buffer, pH 7.0, and analyzed by Western blots using pAb TcaBn-syn antibody as the primary antibody. Fractions cross -reacted with the antibody were pooled and applied to a MonoQ 5/5 column which was equilibrated with 20 mM Tris-HCl, pH 7.0 at lml/mm. The proteins bound to the column were eluted at lml/mm by a linear gradient of 0 to IM NaCl in 20 mM Tris-HCl, pH 7 0 for 30 mm. Fractions above reacted with pAb TcaBn-syn antibody were pooled and subjected to a phenyl-Superose 5/5/ column. Solid (NH4)2Sθ4 added to a final concentration of 1 7 M The solution was then applied onto the column equilibrated with 1.7 M (NH4)2Sθ4 m 50 mM potassium phosphate buffer, pH 7 at lml/mm. Proteins bound to the column were then eluted with a linear gradient of 1.7 M (NH 4 )2Sθ4, 50 mM potassium phosphate, pH 7.0 to 10 mM potassium phosphate, pH 7.0 at 0.5 ml/mm for 60 mm. Fractions were dialyzed overnight against 10 M sodium phosphate buffer, pH 7.0. For the final purification step, fractions reacted with pAb TcaBn-syn antibody above determined by Western analysis were combined and applied to a Mono Q 5/5 column equilibrated with 20 mM Tris-HCl, pH 7.0 at lml/mm. The proteins bound to the column were eluted at lml/mm by a linear gradient of 0 to IM NaCl m 20 mM Tris-HCl, pH 7 0 for 30 mm. The final purified protein fraction contained 6 major peptides examined by SDS-PAGE. 165 kDa, 90 kDa, 64 kDa, 62 kDa, 58 kDa, and 22 kDa. The LD50 of the msecticidal activities of this purified -101- SUBSTΓΓUTE SHEET (RULE 26) fraction were determined to be 100 ng and 500 ng against SCR and ECB, respectively. The above peptides were blotted to PVDF membranes and blots were sent for ammo acids analysis and 5 ammo acid long N-termmal sequencing at Harvard MicroChem and Cambridge ProChem, respectively. The N-termmal ammo acid sequence of the 165 kDa peptide was determined to be identical to peptide TcaC (SEQ ID 2, position 1 to 5) . The N-termmal ammo acid sequence of the 90 kDa peptide was determined to be TcaA lx region of the derived ammo acid sequence for the tcaA gene (SEQ ID NO 33, position 254 to 258) . The N-termmal ammo acid sequence of 64 kDa peptide was determined to be identical to peptide TcaB x (SEQ ID 3, position 1 to 5) . The N-termmal ammo acid sequence of the 62 kDa peptide was determined to be TcaA region of the derived ammo acid sequence for the tcaA gene (SEQ ID NO 33, position 489 to 493) . The N-termmal ammo acid sequence of 58 kDa peptide was determined to be identical to peptide TcaB u (SEQ ID 5, position 1 to 5) . The N-termmal ammo acid sequence of the 22 kDa peptide (SEQ ID NO 62) was determined to be TcaA region, denoted TcaA lv , of the derived ammo acid sequence for the tcaA gene (SEQ ID NO 34, position 98 to 102) It is noted that all tcaA, tcaB, and tcaC genes reside in the same tea operon (Fig. 6A) . Five μg of purified Tea fraction, purified toxin A, and purified toxm B were analyzed by Western blot using the following antibodies individually as primary antibody: pAb TcaBn-syn antibody, mAb CF52 antibody, pAb TcdAii-syn antibody, and pAb Tcdm-syn antibody (Example 21) With pAb TcaBn-syn antibody only the purified Tea peptides fraction reacted, but not toxm A or toxin B. With mAb CF52 antibody, only toxin B reacted but not Tea peptides fraction or tox A. With either pAb TcdAii-syn antibody or pAb Tcdm-syn antibody only tox A reacted, but not Tea peptides fraction or toxm B. This indicated that the secticidal activity observed in the purified Tea peptides fraction is independent of toxm A and toxm B The purified Tea peptide fraction is a third unique protein tox , denoted toxm C. -102- SUBSTΠTJTE SHEET (RULE 26) Exam le 16 Cleavage and Activation of TcbA Peptide In the toxm B complex, peptide TcbAn an d TcbA xll originate from the single gene product TcbA (Example 15) . The processing of TcbA peptide to TcbAn an d TcbA m is presumably by the action of Photorhabdus protease (s), and most likely, the metalloproteases described in Example 10. In some cases, it was noted that when Photorhabdus W-14 broth was processed, TcbA peptide was present in toxm B complex as a major component, m addition to peptides TcbAn and TcbA ι- Identical procedures, described for the purification of toxm B complex (Example 15) , were used to enrich peptide TcbA from tox complex fraction of W-14 broth. The final purified material was analyzed in a 4-20% gradient SDS-PAGE and ma j or peptides were quantified by densitometry . It was determined that TcbA, TcbAn and TcbA lu comprised 58%, 36%, and 6%, respectively, of total protein The identities of these peptides were confirmed by their respective molecular sizes in SDS-PAGE and Western blot analysis using monospecific antibodies The native molecular weight of this fraction was determined to be 860 kDa. The cleavage of TcbA was evaluated by treating the above purified material with purified 38 kDa and 58 kDa W-14 Photorhabdus metalloproteases (Example 10) , and tryps as a control enzyme (Sigma, MO). The standard reaction consisted 17.5 μg the above purified fraction, 1.5 unit protease, and 0.1 M Tris buffer, pH 8.0 in a total volume of 100 μl . For the control reaction, protease was omitted. The reaction mixtures were incubated at 37°C for 90 mm. At the end of the reaction, 20 μl was taken and boiled with SDS-PAGE sample buffer immediately for electrophoresis analysis m a 4-20% gradient SDS-PAGE. It was determined from SDS-PAGE that in both 38 kDa and 58 kDa protease treatments, the amount of peptides TcbA 1;L an d TcbA n increased about 3 -fold while the amount of TcbA peptide decreased proportionally (Table 24) . The relative reduction and augmentation of selected peptides was confirmed by Western blot analyses. Furthermore, gel filtration of the cleaved material revealed that the native molecular size of the complex remained the same. Upon trypsm treatment, peptides TcbA and TcbAn were nonspecifically digested into small peptides This indicated that 38 kDa and 58 kDa Photorhabdus proteases can -103- SUBSTΓΓUTE SHEET (RULE 26) specifically process peptide TcbA into peptides TcbAn and TcbA lu Protease treated and untreated control of the remaining 80 μl reaction mixture were serial diluted with 10 mM sodium phosphate buffer, pH 7 0 and analyzed by SCR bioassay By comparing activity in several dilution, it was determined that the 38 kDa protease treatment increased SCR msecticidal activity approximately 3 to 4 fold. The growth inhibition of remaining insects in the protease treatment was also more severe than control (Table 24) .

SCR larva were grown on coleopteran diet until they reached the fourth instar stage (about 100-125 mg total weight each insect) . SCR gut content was collected as follows: the guts were removed using dissecting scissors and forceps. After removing the excess fatty material that coats the gut lining, about 40 guts were homogenized in a microcentrifuge tube containing 100 μl sterile water. The tube was then centrifuged at 14,000 rpm for 10 minutes and the pellet discarded. The supernatant was stored at a -70°C freezer until use. The processing of tox B by insect gut was evaluated by treating the above purified toxm B with the SCR gut content collected. The reaction consisted 40 μg tox B (1 mg/ml), 50 μl -104- SUBSTΓΓUTE SHEET (RULE 26) SCR gut content, and 0. IM Tris buffer, pH 8.0 in a total volume of 100 μl . For the control reaction, SCR gut content was omitted. The reaction mixtures were incubated at 37°C for overnight. At the end of reaction, 10 μl was withdraw and boiled with equal volume 2x SDS-PAGE sample buffer for SDS-PAGE analysis. The remaining 90 μl reaction mixture was serial diluted with 10 mM sodium phosphate buffer, pH 7.0 and analyzed by SCR bioassay. SDS-PAGE analysis indicated in SCR gut content treatment, peptide TcbA was digested completely into smaller peptides. Analysis of the undenatured toxin fraction showed that the native size, about 860 kDa, remained the same even though larger peptides were fragmented. In SCR bioassays, it was found that the LD50 of SCR gut treated toxin B to be about 70 ng; representing a 10-fold increase. In a separate experiment, protease K treatment completely eliminated toxin activity. Example 17 Screening of the Library for a Gene Encoding the TcdA j ^ Peptide The cloning and characterization of a gene encoding the TcdAή peptide, described as SEQ ID NO: 17 (internal peptide TcdAή-PTlll N-terminal sequence) and SEQ ID NO: 18 (internal peptide TcdAϋ-PT79 N-termmal sequence) was completed. Two pools of degenerate oligonucleotides, designed to encode the amino acid sequences of SEQ ID NO:17 (Table 25) and SEQ ID NO:18 (Table 26), and the reverse complements of those sequences, were synthesized as described in Example 8. The DNA sequence of the oligonucleotides is given below: -105- SUBSTΓΓUTE SHEET (RULE 26) Table 25 Degenerate Oligonucleotide for SEQ ID NO: 17 Table 26 o Degenerate Oligonucleotide for SEQ ID NO: 18 * According to IUPAC-IUB codes for nucleotides, Y = C or T, H A, C or T, N = A, C, G or T, K = G or T, R = A or G, and M = A or C Polymerase Cham Reactions (PCR) were performed essentially as described in Example 8, using as forward primers P2.3.6.CB or P2.3.5, and as reverse primers P2.79.R.1 or P2.79R.CB, in all forward/reverse combinations, using Photorhabdus W-14 genomic DNA as template. In another set of reactions, primers P2.79.2 or P2.79.3 were used as forward primers, and P2.3.5R, P2.3.5RI, and P2.3R.CB were used as reverse primers in all forward/reverse combinations. Only in the reactions containing P2 3.6. CB as the forward primers combined w th P2.79.R.1 or P2.79R.CB as the reverse primers was a non-artifactual amplified product seen, of estimated size (mobility on agarose gels) of 2500 base pairs. The order of the primers used to obtain this amplification product indicates that the peptide fragment TcdAn-PTlll lies ammo-proximal to the peptide fragment TcdA lx -PT79. The 2500 bp PCR products were ligated to the plasmid vector pCR™II (Invitrogen, San Diego, CA) according to the supplier's instructions, and the DNA sequences across the ends of the insert fragments of two isolates (HS24 and HS27) were determined using the supplier's recommended primers and the sequencing methods described previously. The sequence of both isolates was the same. New primers were synthesized based on the determined sequence, and used to prime additional sequencing reactions to obtain a total of 2557 bases of the insert [SEQ ID NO:36] Translation of the partial peptide encoded by SEQ ID No: 36 yields the 845 ammo acid sequence disclosed as SEQ ID NO: 37 Protein homology analysis of this portion of the TcdAn peptide fragment reveals substantial ammo acid homology ( (68% similarity, and 53% identity using the Wisconsin Package Version 8.0, Genetics Computer Group (GCG) , Madison, WI ) to residues 542 to 1390 of protein TcbA [SEQ ID NO: 12] or (60% similarity, and 54% identity using the Wisconsin Package Version 9 0, Genetics Computer Group (GCG), Madison, WI to residues 567 to 1389) ) . It is therefore apparent that the gene represented part by SEQ ID NO: 36 produces a protein of similar, but not identical, ammo acid sequence as the TcbA protein, and which likely has similar, but not identical biological activity as the TcbA protein. In yet another instance, a gene encoding the peptides TcdAn - PK44 and the TcdA lu 58 kDa N-termmal peptide, described as SEQ ID NO:39 (internal peptide TcdA 11 -PK44 sequence) , and SEQ ID NO:41 (TcdAni 58 kDa N-termmal peptide sequence) was isolated. -107- SUBSTΓΓUTE SHEET (RULE 26) Two pools of degenerate oligonucleot.ides, designed to encode the amino acid sequences described as SEQ ID NO: 39 (Table 28) and SEQ ID NO:41 (Table 27) , and the reverse complements of those sequences, were synthesized as described in Example 8, and their DNA sequences . -108- SUBSTΓΓUTE SHEET (RULE 26) Ui Table 27 Degenerate Oligonucleotide for SEO ID NO: 41 o so I Table 28 Degenerate Oligonucleotide for SEO ID NO: 39 Polymerase Chain Reactions (PCR) were performed essentially as described Example 8, using as forward primers Al.44.1 or Al.44.2, and reverse primers A2.3R or A2.4R, m all forward/reverse combinations, using Photorhabdus W-14 genomic DNA as template. In another set of reactions, primers A2.1 or A2.2 were used as forward primers, and A1.44.1R, and A1.44.2R were used as reverse primers in all forward/reverse combinations. Only in the reactions containing Al.44.1 or Al.44.2 as the forward primers combined with A2.3R as the reverse primer was a non-artifactual amplified product seen, of estimated size (mobility on agarose gels) of 1400 base pairs. The order of the primers used to obtain this amplification product indicates that the peptide fragment TcdA 1L -PK44 lies ammo-proximal to the 58 kDa peptide fragment of TcdA lu The 1400 bp PCR products were ligated to the plasmid vector pCR ,M II according to the supplier's instructions. The DNA sequences across the ends of the insert fragments of four isolates were determined using primers similar in sequence to the supplier's recommended primers and using sequencing methods described previously. The nucleic acid sequence of all isolates differed as expected in the regions corresponding to the degenerate primer sequences, but the ammo acid sequences deduced from these data were the same as the actual amino acid sequences for the peptides determined previously, (SEQ ID NOS: 41 and 39) . Screening of the W-14 genomic cosmid library as described Example 8 with a radiolabeled probe comprised of the DNA prepared above (SEQ ID NO:36) identified five hybridizing cosmid isolates, namely 17D9, 20B10, 21D2, 27B10, and 26D1. These cosmids were distinct from those previously identified with probes corresponding to the genes described as SEQ ID NO: 11 or SEQ ID NO: 25. Restriction enzyme analysis and DNA blot hybridizations identified three EcoR I fragments, of approximate sizes 3.7, 3.7, and 1.1 kbp, that span the region comprising the DNA of SEQ ID NO:36. Screening of the W-14 genomic cosmid library using as probe the radiolabeled 1.4 kbp DNA fragment prepared in this example identified the same five cosmids (17D9, 20B10, 21D2, 27B10, and 26D1) . DNA blot hybridization to EcoR I-digested cosmid DNAs also showed hybridization to the same subset of EcoR I fragments as seen with the 2.5 kbp TcdA xl gene probe, indicating that both fragments are encoded on the genomic DNA. -110- SUBSTΓΓUTE SHEET (RULE 26) DNA sequence determination of the cloned EcoR I fragments revealed an uninterrupted reading frame of 7551 base pairs (SEQ ID NO:46) , encoding a 282.9 kDa protein of 2516 ammo acids (SEQ ID NO: 47) . Analysis of the ammo acid sequence of this protein revealed all expected internal fragments of peptides TcdAn (SEQ ID N0S:17, 18, 37, 38 and 39) and the TcdA peptide N-terminus (SEQ ID NO: 41) and all TcdAm internal peptides (SEQ ID NOS.42 and 43) The peptides isolated and identified as TcdAn an TcdAm are each products of the open reading frame, denoted tcdA, disclosed as SEQ ID NO:46. Further, SEQ ID NO:47 shows, starting at position 89, the sequence disclosed as SEQ ID NO: 13, which is the N-termmal sequence of a peptide of size approximately 201 kDa, indicating that the initial protein produced from SEQ ID NO: 46 is processed in a manner similar to that previously disclosed for SEQ ID NO: 12. In addition, the protein s further cleaved to generate a product of size 209.2 kDa, encoded by SEQ ID NO:48 and disclosed as SEQ ID NO-.49 (TcdAn peptide), and a product of size 63.6 kDa, encoded by SEQ ID NO: 50 and disclosed as SEQ ID NO: 51 (TcdAm peptide) Thus, it s thought that the msecticidal activity identified as toxm A (Example 15) derived from the products of SEQ ID NO: 46, as exemplified by the full-length protein of 282.9 kDa disclosed as SEQ ID NO: 47, is processed to produce the peptides disclosed as SEQ ID NOS: 49 and 51. It is thought that the msecticidal activity identified as tox B (Example 15) derives from the products of SEQ ID NO: 11, as exemplified by the 280 6 kDa protein disclosed as SEQ ID NO.12. This protein is proteolytically processed to yield the 207 6 kDa peptide disclosed as SEQ ID NO: 53, which is encoded by SEQ ID NO: 52, and the 62.9 kDa peptide having N-termmal sequence disclosed as SEQ ID NO: 40, and further disclosed as SEQ ID NO: 55, which is encoded by SEQ ID NO: 54. Ammo acid sequence comparisons between the proteins disclosed as SEQ ID NO: 12 and SEQ ID NO: 47 reveal that they have 69% similarity and 54% identity using the Wisconsin Package Version 8.0, Genetics Computer Group (GCG), Madison, WI or 60% similarity and 54% identity using version 9.0 of the program This high degree of evolutionary relationship is not uniform throughout the entire ammo acid sequence of these peptides, but is higher towards the carboxy- erminal end of the proteins, since the peptides disclosed as SEQ ID NO: 51 (derived from SEQ ID NO.47) and SEQ ID -111- SUBSTΓΠJTE SHEET (RULE 26) NO: 55 (derived from SEQ ID NO: 12) have 76% similarity and 64% identity using the Wisconsin Package Version 8.0, Genetics Computer Group (GCG) , Madison, WI or 71% similarity and 64% identity using version 9.0 of the program. Example 18 Control of European Cornborer-Induced Leaf Damaσe on Maize Plants by Spray Application of Photorhabdus (Strain W-14) Broth The ability of Photorhabdus toxm(s) to reduce plant damage caused by insect larvae was demonstrated by measuring leaf damage caused by European corn borer [ Ostrinia nubilalis) infested onto maize plants treated with Photorhabdus broth. Fermentation broth from Photorhabdus strain W-14 was produced and concentrated approximately 10-fold using ultraflltration (10,000 MW pore-size) as described in Example 13. The resulting concentrated broth was then filter sterilized using 0.2 micron nitrocellulose membrane filters. A similarly prepared sample of uninoculated 2% proteose peptone #3 was used for control purposes. Maize plants (an mbred line) were grown from seed to vegetative stage 7 or 8 in pots containing a soilless mixture in a greenhouse (27°C day,- 22°C night, about 50%RH, 14 hr day-length, watered/fertilized as needed) . The test plants were arranged in a randomized complete block design (3 reps/treatment, 6 plants/treatment) in a greenhouse with temperature about 22°C day; 18°C night, no artificial light and with partial shading, about 50%RH and watered/fertilized as needfcϊ Treatments (uninoculated media and concentrated Photorhabdus broth) were applied with a syringe sprayer, 2.0 mis applied from directly (about 6 inches) over the whorl and 2.0 additional mis applied in a circular motion from approximately one foot above the whorl In addition, one group of plants received no treatment. After the treatments had dried (approximately 30 minutes) , twelve neonate European corn borer larvae (eggs obtained from commercial sources and hatched in-house) were applied directly to the whorl After one week, the plants were scored for damage to the leaves using a modified Guthrie Scale (Koziel, M.

Bio/Technology, 11, 194-195.) and the scores were compared statistically [T-test (LSD) p<0.05 and Tukey's Studentized Range (HSD) Test p<0.1] . The results are shown in Table 29. For reference, a score of 1 represents no damage, a score of 2 represents fine "window pane" damage on the unfurled leaf with no pmhole penetration and a score of 5 represents leaf penetration with elongated lesions and/or mid rib feeding evident on more than three leaves (lesions < 1 inch) . These data indicate that broth or other protein containing fractions may confer protection against specific insect pests when delivered m a sprayable formulation or when the gene or derivative thereof, encoding the protein or part thereof, is delivered via a transgenic plant or microbe.

Ex mple 19 Genetic Engineering of Genes for Expression m E. coli Summary of Constructions A series of plasmids were constructed to express the tcbA gene of Photorhabdus W-14 in Escherichia coli . A list of the plasmids is shown in Table 30. A brief description of each construction follows as well as a summary of the E. coli expression data obtained. -113- SUBSTΓΓUTE SHEET (RULE 26) Table 30 Expression Plasmids for the tcbA Gene revia i n : = , =c oramp en co , mp=ampιcι m Construction of PDAB2025 In Example 9, a large EcoR I fragment which hybridizes to the TcbA xl probe is described. This fragment was subcloned into pBC (Stratagene, La Jolla CA) to create pDAB2025. Sequence analysis indicates that the fragment is 8816 base pairs The fragment encodes the tcbA gene with the initiating ATG at position 571 and the terminating TAA at position 8086 The fragment therefore carries 570 base pairs of Photorhabdus DNA upstream of the ATG and 730 base pairs downstream of the TAA. Construction of Plasmid pDAB2026 The tcbA gene was PCR amplified from plasmid pDAB2025 using the following primers,- 5' primer <SlAc51) 5' TTT AAA CCA TGG GAA ACT CAT TAT CAA GCA CTA TC 3' and 3' primer (SlAc31) 5' TTT AAA GCG GCC GCT TAA CGG ATG GTA TAA CGA ATA TG 3' PCR was performed using a TaKaRa LA PCR kit from PanVera (Madison, WI) in the following reaction: 57.5 microliters water, 10 microliters 10X LA buffer, 16 microliters dNTPs (2.5 mM each stock solution), 20 microliters each primer at 10 pmoles/ microliters, 300 ng of the plasmid pDAB2025 containing the W-14 tcbA gene and one microliter of TaKaRa LA Taq polymerase. The cycling conditions were 98°C/20 sec, 68°C/5 mm, 72°C/10 min for 30 cycles. A PCR product of the expected about 7526 bp was isolated in a 0.8% agarose gel m TBE (100 mM Tris, 90 mM boric acid, 1 mM EDTA) buffer and purified using a Qiaex II kit from Qiagen (Chatsworth, CA) . The purified tcbA gene was digested with Neo I and Wot T and ligated into the baculovirus transfer vector pAcGP67B (PharM gen (San Diego, CA) ) and transformed into DH5α E. coli . The resulting recombinant is called pDAB2026 The tcbA gene was then cut from pDAB2026 and transferred to pET27b to create plasmid pDAB2027. A missense mutation the tcbA gene was repaired m pDAB2027. The repaired tcbA gene contains two changes from the sequence shown m Sequence ID NO: 11, an A>G at 212 changing an asparagme 71 to serine 71 and a G>A at 229 changing an alanme 77 to threon e 77. These changes are both upstream of the proposed TcbA ι:L N " terminus . Construction of DDAB202B The tcbA coding region of pDAB2027 was transferred to vector pET15b. This was accomplished using shotgun ligations, the DNAs were cut with restriction enzymes Neo I and Xho I The resulting recombinant is called pDAB2028. Expression of TcbA m E. coli from Plasmid pDAB2028 Expression of tcbA in E. coli was obtained by modification of the methods previously described by Studier et al . (Studier, F.W., Rosenberg, A., Dunn, J., and Dubendorff, J., (1990) Use of T7 RNA polymerase to direct expression of cloned genes. Methods Enzymol . , 185. 60-89.) Competent E. coli cells strain BL2KDE3) were transformed with plasmid pDAB2028 and plated on LB agar containing 100 μg/mL ampicillm and 40 mM glucose The transformed cells were plated to a density of several hundred isolated colonies/plate. Following overnight incubation at 37°C the cells were scraped from the plates and suspended LB broth containing 100 μg/mL ampicillm. Typical culture volumes were from 200-500 mL. At time zero, culture densities (OD600) were from 0.05-0.15 depending on the experiment. Cultures were shaken at one of three temperatures (22°C, 30°C or 37°C) until a density of 0.15-0.5 was obtained at which time they were induced with 1 mM isopropylthio-β-galactoside (IPTG) Cultures were incubated at the designated temperature for 4-5 hours and then were transferred to 4°C until processing (12-72 hours) . Purification and Characterization of TcbA Expressed in E. coli from Plasmid ΩDAB2028 E. coli cultures expressing TcbA peptides were processed as follows Cells were harvested by centrifugation at 17,000 x G and the media was decanted and saved in a separate container -115- SUBSTΓΠJTE SHEET (RULE 26) The media was concentrated about 8x using the M12 (Amicon, Beverly MA) filtration system and a 100 kD molecular mass cut-off filter. The concentrated media was loaded onto an anion exchange column and the bound proteins were eluted with 1.0 M NaCl. The 1.0 M NaCl elution peak was found to cause mortality against Southern corn rootworm (SCR) larvae Table 30). The 1.0 M NaCl fraction was dialyzed against 10 mM sodium phosphate buffer pH 7.0, concentrated, and subjected to gel filtration on Sepharose CL-4B (Pharmacia, Piscataway, NJ) . The region of the CL-4B elution profile corresponding to calculated molecular weight (about 900 kDa) as the native W-14 tox complex was collected, concentrated and bioassayed against larvae. The collected 900 kDa fraction was found to have msecticidal activity (see Table 31 below) , with symptomology similar to that caused by native W-14 tox complex This fraction was subjected to Protemase K and heat treatment, the activity both cases was either eliminated or reduced, providing evidence that the activity is prote aceous m nature In addition, the active fraction tested immunologically positive for the TcbA and TcbA ul peptides in immunoblot analysis when tested with an anti-TcbAm monoclonal antibody (Table 31) The cell pellet was resuspended in 10 mM sodium phosphate buffer, pH=7 0, and lysed by passage through a Bιo-Neb' cell nebulizer (Glas-Col Inc., Terra Haute, IN) The pellets were -116- SUBSTΓΓUTE SHEET (RULE 26) treated with DNase to remove DNA and centrifuged at 17,000 x g to separate the cell pellet from the cell supernatant. The supernatant fraction was decanted and filtered through a 0.2 micron filter to remove large particles and subjected to anion exchange chromatography. Bound proteins were eluted with 1.0 M NaCl, dialyzed and concentrated using Biomax™ (Millipore Corp, Bedford, MA) concentrators with a molecular mass cut-off of 50,000 Daltons. The concentrated fraction was subjected to gel filtration chromatography using Sepharose CL-4B beaded matrix. Bioassay data for material prepared in this way is shown m Table 30 and is denoted as "TcbA Cell Sup". In yet another method to handle large amounts of material, the cell pellets were re-suspended in 10 mM sodium phosphate buffer, pH = 7 0 and thoroughly homogenized by using a Kontes Glass Company (Vmeland, NJ) 40 ml tissue grinder The cellular debris was pelleted by centrifugation at 25,000 x g and the cell supernatant was decanted, passed through a 0.2 micron filter and subjected to anion exchange chromatography using a Pharmacia 10/10 column packed with Poros HQ 50 beads The bound proteins were eluted by performing a NaCl gradient of 0.0 to 1.0 M Fractions containing the TcbA protein were combined and concentrated using a 50 kDa concentrator and subjected to gel filtration chromatography using Pharmacia CL-4B beaded matrix. The fractions containing TcbA oligomer, molecular mass of approximately 900 kDa, were collected and subjected to anion exchange chromatography using a Pharmacia Mono Q 10/10 column equilibrated with 20 mM Tris buffer pH = 7.3 A gradient of 0.0 to 1.0 M NaCl was used to elute recombinant TcbA protein. Recombinant TcbA eluted from the column at a salt concentration of approximately 0.3-0.4 M NaCl, the same olarity at which native TcbA oligomer is eluted from the Mono Q 10/10 column. The recombinant TcbA fraction was found to cause SCR mortality in bioassay experiments similar to those in Table 31. A second set of expression constructions were prepared and tested for expression of the TcbA protein toxm. Construction of pDAB2030. An Expression Plasmid for the tcbA Coding Region The plasmid pDAB2028 (see herein) contains the tcbA coding region m the commercial vector pET15 (Novagen, Madison, WI), -117- SUBSTΓΠJTE SHEET (RULE 26) encodes an ampicillm selection marker. The plasmid pDAB2030 was created to express the tcbA coding region from a plasmid which encodes a kanamycm selection marker. This was done by cutting pET27 (Novagen, Madison, WI) a kanamycm selection plasmid, and pDAB2028 with Xba I and Xho I . This releases the entire multiple cloning site, including the tcbA coding region from plasmid pDAB2028. The two cut plasmids, were mixed and ligated Recombinant plasmids were selected on kanamycm and those containing the pDAB2028 fragment were identified by restriction analysis. The new recombinant plasmid is called pDAB2030. Cons ruc ion of Plas id pDAB Q3;i , Correction of Mutations in tcbA The two mutations in the N-terminus of the tcbA coding region as described in Example 19 (Sequence ID NO: 11; A>G at 212 changing an asparagme 71 to serine 71; G>A at 229 changing an alanine 77 to threonme 77) were corrected as follows A PCR product was generated using the primers TH50 (5' ACC GTC TTC TTT ACG ATC AGT G 3') and SlAc51(5' TTT AAA CCA TGG GAA ACT CAT TAT CAA GCA CTA TC 3 ' ) and pDAB2025 as template to generate a 1778 bp product This PCR product was cloned into plasmid pCR2 1 (Invitrogen, San Diego, CA) and a clone was isolated and sequenced The clone was digested with Neo I and Pm Al and a 1670 bp fragment was purified from a 1% agarose gel. A plasmid containing the mutated tcbA coding region (pDAB2030) was digested with iVco I and Not I and purified away from the 1670 bp fragment m a 0.8% agarose with Qiaex II (Qiagen, Chatsworth, CA) . The corrected Neo I /Pin Al fragment was then ligated into pDAB2030 The ligated DNA was transformed into DH5α E. coli . A clone was isolated, sequenced and found to be correct. This plasmid, containing the corrected tcbA coding region, is called pDAB2031 Construction of PPAB2Q33 and DAB2Q34 Expression Plasmids for t bA The expression plasmids pDAB2025 and pDAB2027-2031 all rely on the Bacteπophage T7 expression system An additional vector system was used for bacterial expression of the tcbA gene and its derivatives The expression vector Trc99a (Pharmacia Biotech, Piscataway, NJ) contains a strong trc promoter upstream of a multiple cloning site with a 5' Neo I site which is compatible with the tcbA coding region from pDAB2030 and 2031 However, the plasmid does not have a compatible 3 ! site Therefore, the Hind III site of Trc99a was cut and made blunt by treatment with T4 DNA -118- SUBSTΓΓUTE SHEET (RULE 26) polymerase (Boehringer Mannheim, Indianapolis, IN) . The vector plasmid was then cut by Neo I followed by treatment with alkaline phosphatase. The plasmids pDAB2030 and pDAB2031 were each cut with Xho I (cuts at the 3' end of the tcbA coding region) followed by treatment with T4 DNA polymerase to blunt the ends . The plasmids were then cut with Neo I, the DNAs were extracted with phenol, ethanol precipitated and resuspended in buffer. The Trc99a and pDAB2030 and pDAB2031 plasmids were mixed separately, ligated and transformed into DH5α cells and plated on LB media containing ampicillin and 50 mM glucose. Recombinant plasmids were identified by restriction digestion. The new plasmids are called pDAB2033 (contains the tcbA coding sequence with the two mutations in tcbA-^) and pDAB2034 (contains the corrected version of tcbA from pDAB2031) . Construction of Plasmid pDAB2032: An Expression Plasmid for tShΔuΔm A plasmid encoding the TcbAϋA j ^ portion of TcbA was created in a similar way as plasmid pDAB2031. A PCR product was generated using TH42 (5' TAG GTC TCC ATG GCT TTT ATA CAA GGT TAT AGT GAT CTG 3') and TH50 (5' ACC GTC TTC TTT ACG ATC AGT G 3') primers and plasmid pDAB2025 as template. This yielded a product of 1521 bp having an initiation codon at the beginning of the coding sequence of tcbA±i_ . This PCR product was isolated in a 1% agarose gel and purified. The purified product was cloned into pCR2.1 as above and a correct clone was identified by DNA sequence analysis. This clone was digested with Neo I and Pin Al, a 1414 bp fragment was isolated in a 1% agarose gel and ligated into the Neo I and Pin Al sites of plasmid pDAB2030 and transformed into DH5 E. coli . This new plasmid, designed to express in E. coli , is called pDAB2032. Expression of tcbA and tcbA ±i ^ ii from Plasmids pDAB2030. pDAB2031 and pDAB2032 Expression of tcbA in E. coli from plasmids pDAB2030, pDAB2031 and pDAB2032 was as described herein, except expression of tcbAnA-ii -i was done in E. coli strain HMS174(DE3) (Novagen, Madison, I) . -119- SUBSTΓΠJTE SHEET (RULE 25) Expression of tcbA from Plasmid pDAB2033 The plasmid pDAB2033 was transformed into BL21 cells (Novagen, Madison, WI) and plated on LB containing 100 micrograms/mL ampicillin and 50 mM glucose. The plates were spread such that several hundred well separated colonies were present on each plate following incubation at either 30°C or 37°C overnight. The colonies were scraped from the plates and suspended m LB containing 100 micrograms/mL ampicillm, but no glucose. Typical culture volume was 250 mL m a single 1 L baffle bottom flask. The cultures were induced when the culture reached a density of 0.3-0.6 OD600 n . Most often this density was achieved immediately after suspension of the cells from the plates and did not require a growth period in liquid media. Two induction methods were used. Method 1: cells were induced with 1 mM IPTG at 37°C. The cultures were shaken at 200 rpm on a platform shaker for 5 hours and harvested. Method 2: The cultures were induced with 25 micromolar IPTG at 30°C and shaken at 200 rpm for 15 hours at either 20°C or 30°C. The cultures were stored at 4°C until used for purification. Purification of TcbA from E. coli Purification, bioassay and immunoblot analysis of TcbA and TcbA 11 A 111 was as described herein. Results of several representative E. coli expression experiments are shown Table 32. All materials shown in Table 32 were purified from the media fraction of the cultures. The predicted native molecular weight is approximately 900 kD as described herein The purity of the samples, the amount of TcbA relative to contaminating proteins, varied with each preparation.

In some cases, the TcaB protein toxm was pretreated with proteases (Example 16) that had been isolated from W-14 broth as previously described (Example 15) . Protein molecular mass was determined using matrix-assisted laser desorption lomzation time- of-flight mass spectroscopy, hereinafter MALDI-TOF, on a VOYAGER BIOSPECTROMETRY workstation with DELAYED EXTRACTION technology (PerSeptive Biosystems, Frammgham, MA). Typically, the protein of mte r re " s rrGO-500 pmoles m 5 μl) was mixed with 1 μl of acetonitπle and dialyzed for 0.5 to 1 h on a Millipore VS filter having a pore size of 0.025 μM (Millipore Corp. Bedford, MA). Dialysis was performed by floating the filter on water (shinny side up) followed by adding protem-acetonitrile mixture as a droplet to the surface of the filter. After dialysis, the dialyzed protein removed using a pipette and was then mixed with a matrix consisting of s apinic acid and trifluoroacetic acid according to manufacturers instructions. The protein and matrix were allowed to co-crystallize on a about 3 cm 2 gold-plated sample plate (PerSeptive Corp.) . Excitation of the crystals and subsequent mass analysis was performed using the following conditions: laser setting of 3050; pressure of 4.55e-07, low mass gate of 1500.0; negative ions off; accelerating voltage of 25,000; grid voltage of -121- SUBSTΓΓUTE SHEET (RULE 26) 90.0%; guide wire voltage of 0.010%; linear mode; and a pulse delay time of 350 ns . Protein mass analysis data are shown m Table 33. The data obtained from MALDI-TOF was compared to that hypothesized from gene sequence information and as previously determined by SDS-PAGE Table 33 Molecular Analysis of Peptides bv MALDI-TOF.

Comprehensive DNA and deduced ammo acid sequence data for these peptides indicated that the sequence homology between some of these peptides was substantial. If a whole peptide was used as the immunogen to induce antibody production, the resulting antibodies might bind to multiple peptides in the toxm preparation. To avoid this problem antibodies were generated that would bind specifically to a unique region of each peptide of interest The unique region (subpeptide) of each target peptide was selected based on the analyses described below Each entire peptide sequence was analyzed using MacVector Protein Analysis Tool (IBI Sequence Analysis Software, International Biotechnologies, Inc., P. O Box 9558, New Haven, CT 06535) to determine its antigenicity index. This program was designed to locate possible externally-located ammo acid -122- SUBSTΓΓUTE SHEET (RULE 26) sequences, i.e., regions that might be antigenic sites. This method combined information from hydrophilicity, surface probability, and backbone flexibility predictions along with the secondary structure predictions order to produce a composite prediction of the surface contour of a protein. The scores for each of the analyses were normalized to a value between -1 0 and +1 0 (MacVector Manual) . The antigenicity index value was obtained for the entire sequence of the target peptide. From each peptide, an area covering 19 or more ammo acids that showed a high antigenicity index from the original sequence was re-analyzed to determine the antigenicity index of the subpeptide without the flanking residues This re-analysis was necessary because the antigenicity index of a peptide could be influenced by the flanking ammo acid residues. If the isolated subpeptide sequence did not maintain a high antigenicity index, a new region was chosen and the analysis was repeated Each selected subpeptide sequence was aligned and compared to all seven target peptide sequences using MacVector ™ alignment program. If a selected subpeptide sequence showed identity (greater than 20%) to another target peptide, a new 19 or more ammo acid region was isolated and re-analyzed. Unique subpeptide sequences covering 19 or more ammo acid showing high antigenicity index were selected from all target peptides. The sequences of seven subpeptides were sent to Gene ed Biotechnology Inc. The last ammo acid residue on each subpeptide was deleted because it showed no apparent effect on the antigenicity index. A cysteine residue was added to the N-terminal of each subpeptide sequence, except TcaBx-syn which contains an internal cysteine residue. The present of a cysteine residue facilitates conjugation of a carrier protein (KLH) The final peptide products corresponding to the appropriate toxm peptides and SEQ ID NO.s are shown in Table 34. -123- SUBSTΓΓUTE SHEET (RULE 26) Table 34 Ammo Acid Sequences for Synthetic Peptides _ SEO ID No. P_£p_ιde Amino Ad Sequence NH2 -( C ) LRGN S P TN P D KD G I FAQVA NH2 -( C) YT PDQT P S FYETAF R SADG NH2 -HGQ S YNDNNY CN FT L S I NT NH2 -( C) VD P KTLQRQQAGGDGTGS S NH2- { C ) Y K A P Q R Q E D G D S N A V T Y D K NH2 -( C) YNEN P S S E D KKWY F S S KDD NH2 -( C ) FD S Y S Q L Y E EN I NAGE QRA NH2 -( C ) N PNNS S NKLM F Y PVYQY S GNT NH2 -( C) VS QG S GSAG S GNNNLA FGAG Each conjugated synthetic peptide was injected into two rabbits according to Genemed accelerated program The pre- and post-immune sera were available for testing after one month.

Subsequently, the sera were tested with the whole target peptides, by Western blot analysis Two batches of partially purified Photorhabdus strain W-14 toxin complex was used as the antigen. The two samples had shown activity against the Southern corn rootworm. Their peptide patterns on an SDS-PAGE gel were slightly different. Pre-cast SDS-polyacrylamide gels with 4-20% gradient (Integrated Separation Systems, Natick, MA 01760) were used Between 1 to 8 μg of protein was applied to each gel well Electrophoresis was performed and the protein was electroblotted onto Hybond-ECL nitrocellulose membrane (Amersham International) The membrane was blocked with 10% milk in TBST (25 mM Tris HCl pH 7.4, 136 mM NaCl, 2.7 mM KCl, 0 1% Tween 20) for one hour at room temperature Each rabbit serum was diluted in 10% milk/TBST to 1:500. Other dilutions between 1.50 to 1 1000 were also used. The serum was added to the membrane and placed on a platform rocker for at least one hour. The membrane was washed thoroughly with the blocking solution or TBST. A 1.2000 dilution of secondary antibodies (goat anti -mouse IgG conjugated to horse radish peroxidase,- BioRad Laboratories) n 10% milk/TBST was applied to the membrane placed on a platform rocker for one hour The membrane was subsequently washed with excess amount of TBST The -124- SUBSTΓΓUTE SHEET (RULE 26) detection of the protein was performed by using an ECL (Enhanced Chemiluminescence) detection kit (Amersham International) . Western blot analyses were performed to identify binding specificity of each anti-synthetic peptide antibodies. All synthetic polyclonal antibodies showed specificity toward to processed and, when applicable, unprocessed target peptides from protein fractions derived from Photorhabdus culture broth. -Various antibodies were shown to recognize either unprocessed or processed recombinant proteins derived from heterologous expression systems such as bacteria or insect cells, using baculovirus expression constructs. In one case, the anti-TcbAiϋ-syn antibody showed some cross-reactivity to anti-TcdAiϋ peptide. In a second case, the anti-TcaC-syn antibody, recognized an unidentified 190 kDa peptide in W-14 toxin complex fractions. Example 22 Characterization of Photorhabdus Strains In order to establish that the collection described herein was comprised of Photorhabdus strains, the strains herein were assessed in terms of recognized microbiological traits that are characteristic of the bacterial genus Photorhabdus and which differentiate it from other Enterobacteriaceae and Xenorhabdus spp . (Farmer, J. J. 1984. Bergey's Manual of Systemic Bacteriology, Vol 1. pp. 510-511. (ed. Kreig N. R. and Holt, J. G.). Williams & Wilkins, Baltimore.,- Akhurst and Boemare, 1988, J. Gen. Microbiol. 134, 1835-1845; Forst and Nealson, 1996. Microbiol. Rev. 60, 21- 43) . These characteristic traits are as follows: Gram stain negative rods, organism size of 0.3-2 μm in width and 2-10 μm in length [with occasional filaments (15-50 μm) and spheroplasts] , yellow to orange/red colony pigmentation on nutrient agar, presence of crystalline inclusion bodies, presence of catalase, inability to reduce nitrate, presence of bioluminescence, ability to take up dye from growth media, positive for protease production, growth at temperatures below 37°C, survival under anaerobic conditions and positively motile. (Table 33) . Test methods were checked using reference Escherichia coli , Xenorhabdus and Photorhabdus strains. The overall results are consistent with all strains being part of the family Enterobacteriaceae and the genus Photorhabdus . Note that DEP1, DEP2, and DEP3 refer to Photorhabdus strains obtained -125- SUBSTTΓUTE SHEET (RULE 26) from the American Type Culture Collection, 12301 Parklawn Drive, Rockville, MD 20852 USA (#29304, 29999 and 51583, respectively). A luminometer was used to establish the bioluminescence associated with these Photorhabdus strains. To measure the presence or absence of relative light emitting units, the broths from each strain (cells and media) were measured at three time intervals after inoculation in liquid culture (24, 48, 72 hr) and compared to background luminosity (uninoculated media) . Several Xenorhabdus strains were tested as negative controls for luminosity. Prior to measuring light emission from the various broths, cell density was established by measuring light absorbance (560 nM) in a Gilford Systems (Oberl , OH) spectrophotometer using a sipper cell. The resulting light emitting units could then be normalized to density of cells. Aliquots of the broths were placed into 96-well microtiter plates (100 μl each) and read in a Packard Lumicount™ luminometer (Packard Instrument Co., Meπden, CT) . The measurement period for each sample was 0.1 to 1.0 second. The samples were agitated in the luminometer for 10 sec prior to taking readings. A positive test was determined as being about 5 -fold background luminescence (about 1-15 relative light units) . In addition, degree of colony luminosity was confirmed with photographic film overlays and by eye, after visual adaptation in a darkroom. The Gram's staining characteristics of each strain were established with a commercial Gram's stain kit (BBL, Cockeysville, MD) used in conjunction with Gram's stain control slides (Fisher Scientific, Pittsburgh, PA) . Microscopic evaluation was then performed using a Zeiss microscope (Carl Zeiss, Germany) 100X oil immersion objective lens (with 10X ocular and 2X body magnification) . Microscopic examination of individual strains for organism size, cellular description and inclusion bodies (the latter two observations after logarithmic growth) was performed using wet mount slides (10X ocular, 2X body and 40X objective magnification) and phase contrast microscopy with a micrometer (Akhurst, R. J. and Boemare, N. E. 1990. Entomopathogenic Nematodes in Biological Control (ed. Gaugler, R. and Kaya, H.). pp. 75-90. CRC Press, Boca Raton, USA.,- Baghdiguian S., Boyer-Giglio M. H., Thaler, J. 0., Bonnot G., Boemare N. 1993. Biol. Cell 79, 177- 185.) . Colony pigmentation was observed after inoculation on Bacto nutrient agar, (Difco Laboratories, Detroit, MI) prepared as per -126- SUBSTΓΓUTE SHEET (RULE 26) label instructions. Incubation occurred at 28 °C and descriptions were produced after 5 days. To test for the presence of the enzyme catalase, a colony of the test organism was removed on a small plug from a nutrient agar plate and placed into the bottom of a glass test tube. One ml of a household hydrogen peroxide solution was gently added down the side of the tube. A positive reaction was recorded when bubbles of gas (presumptive oxygen) appeared immediately or withm 5 seconds . Controls of uninoculated nutrient agar and hydrogen peroxide solution were also examined. To test for nitrate reduction, each culture was inoculated into 10 ml of Bacto Nitrate Broth (Difco Laboratories, Detroit, MI). After 24 hours incubation with gentle agitation at 28 °C, nitrite production was tested by the addition of two drops of sulfanilic acid reagent and two drops of alpha-naphthylamme reagent (see Difco Manual, 10th edition, Difco Laboratories, Detroit, MI, 1984) The generation of a distinct pink or red color indicates the formation of nitrite from nitrate whereas the lack of color formation indicates that the strain is nitrate reduction negative. In the latter case, finely powdered zmc was added to further confirm the presence of unreduced nitrate,- established by the formation of nitrite and the resultant red color The ability of each strain to uptake dye from growth media was tested with Bacto MacConkey agar containing the dye neutral red; Bacto Tergιtol-7 agar containing the dye bromothymol blue and Bacto EMB Agar containing the dye eosm-Y (formulated agars from Difco Laboratories, Detroit, MI, all prepared according to label instructions) After inoculation on these media, dye uptake was recorded after incubation at 28°C for 5 days Growth on these latter media is characteristic for members of the family Enterobacteriaceae . Motility of each strain was tested using a solution of Bacto Motility Test Medium (Difco Laboratories, Detroit, MI) prepared as per label instructions. A butt-stab inoculation was performed with each strain and motility was judged macroscopically by a diffuse zone of growth spreading from the line of inoculum. The production of protease was tested by observing hydrolysis of gelatin using Bacto gelatin (Difco Laboratories, Detroit, MI) made as per label instructions Cultures were inoculated and the tubes or plates were incubated at 28 °C for 5 days Gelatin hydrolysis was then checked at room temperature, I e. less than 22 °C. To assess growth at different -127- SUBSTΓΓUTE SHEET (RULE 26) temperatures, agar plates [2% proteose peptone #3 with two percent Bacto-Agar (Difco, Detroit, MI) m deionized water] were streaked from a common source of inoculum. Plates were incubated at 20, 28 and 37°C for up to three weeks. The incubator temperature levels were checked with an electronic thermocouple and meter to insure valid temperature settings. Oxygen requirements for Photorhabdus strains were tested in the following manner. A butt -stab inoculation into fluid thioglycolate broth medium (Difco, Detroit, MI) was made. The tubes were incubated at room temperature for one week and cultures were then examined for type and extent of growth. The indicator resazurin demonstrates the presence of medium oxygenation or the aerobiosis zone (Difco Manual, 10th edition, Difco Laboratories, Detroit, MI). Growth zone results obtained for the Photorhabdus strains tested were consistent with those of a facultative anaerobic microorganism. In the case of unclear results, the final agar concentration of fluid thioglycolate broth medium was raised to 0.75% and the growth characteristics rechecked. -128- SUBSTTTUTE SHEET (RULE 26) Table ,35 Taxonomic Traits of Photorhabdus Strains *: A=Gram's stain, B=Crystaline inclusion bodies, C=Bioluminescence, D=Cell form, E=Motility, F=Nitrate reduction, G=Presence of catalase, H=Gelatin hydrolysis, I=Dye uptake, J=Pigmentation on Nutrient Agar (some color shifts after Day 5) , K=Growth on EMB agar, L=Growth on MacConkey agar, M=Growth on Tergitol-7 agar, N =Facultative anaerobe, 0=Growth at 20°C, P=Growth at 28°C, Q=Growth at 37°C. t: +=positive for trait, - =negative for trait; rd=rod, S=sized within Genus descriptors . § : W = white, CR = cream, Y =yellow, YT=yellow tan, T=tan PO=pale orange, O=orange, PR=pale red, R=red. The evolutionary diversity of the Photorhabdus strains m our collection was measured by analysis of PCR (Polymerase Cham Reaction) mediated genomic fingerprinting using genomic DNA from each strain. This technique is based on families of repetitive DNA sequences present throughout the genome of diverse bacterial species (reviewed by Versalovic, J. , Schneider, M., DE Bruijn, F. J. and Lupski , J. R. 1994. Methods Mol. Cell. Biol., 5, 25-40). Three of these, repetitive extragenic palindromic sequence (REP), enterobacterial repetitive mtergenic consensus (ERIC) and the BOX -129- SUBSTΓΓUTE SHEET (RULE 26) element are thought to play an important role m the organization of the bacterial genome. Genomic organization is believed to be shaped by selection and the differential dispersion of these elements withm the genome of closely related bacterial strains can be used to discriminate these strains (e.g., Louws, F. J. , Fulbright, D. W., Stephens, C. T. and DE Bruijn, F. J. 1994. Appl. Environ. Micro. 60, 2286-2295) . Rep-PCR utilizes oligonucleotide primers complementary to these repetitive sequences to amplify the variably sized DNA fragments lying between them. The resulting products are separated by electrophoresis to establish the DNA "fingerprint" for each strain. To isolate genomic DNA from our strains, cell pellets were resuspended in TE buffer (10 mM Tris-HCl, 1 mM EDTA, pH 8.0) to a final volume of 10 ml and 12 ml of 5 M NaCl was then added. This mixture was centrifuged 20 mm. at 15,000 x g. The resulting pellet was resuspended in 5.7 ml of TE and 300 μl of 10% SDS and 60 μl 20 mg/ml protemase K (Gibco BRL Products, Grand Island, NY) were added. This mixture was incubated at 37°C for 1 hr, approximately 10 mg of lysozyme was then added and the mixture was incubated for an additional 45 mm. One illiliter of 5M NaCl and 800 μl of CTAB/NaCl solution (10% w/v CTAB, 0.7 M NaCl) were then added and the mixture was incubated 10 mm. at 65°C, gently agitated, then incubated and agitated for an additional 20 min. to aid in clearing of the cellular material An equal volume of chloroform/isoamyl alcohol solution (24.1, v/v) was added, mixed gently then centrifuged. Two extractions were then performed with an equal volume of phenol/chloro orm/isoamyl alcohol (50:49:1) . Genomic DNA was precipitated with 0.6 volume of isopropanol . Precipitated DNA was removed with a glass rod, washed twice with 70% ethanol, dried and dissolved m 2 ml of STE (10 mM Tris -HCl pH8.0, 10 mM NaCl, 1 mM EDTA) . The DNA was then quantitated by optical density at 260 nm. To perform rep-PCR analysis of Photorhabdus genomic DNA the following primers were used, REP1R-I; 5' -IIIICGICGICATCIGGC-3 ' and REP2-I; 5 ' -ICGICTTATCIGGCCTAC-3 ' PCR was performed using the following 25μl reaction: 7.75 μl H2O, 2.5 μl 10X LA buffer (PanVera Corp., Madison, WI), 16 μl dNTP mix (2.5 mM each) , 1 μl of each primer at 50 pM/μl, 1 μl DMSO, 1.5 μl genomic DNA (concentrations ranged from 0.075-0.480 μg/μl) and 0.25 μl TaKaRa EX Taq (PanVera Corp., Madison, WI) The PCR -130- SUBSTTTUTE SHEET (RULE 26) amplification was performed in a Perkm Elmer DNA Thermal Cycler (Norwalk, CT) using the following conditions. 95°C/7 min. then 35 cycles of; 94°C/1 mm.,44°C/l mm., 65°C/8 mm., followed by 15 mm. at 65°C. After cycling, the 25 μl reaction was added to 5 μl of 6X gel loading buffer (0.25% bromophenol blue, 40% w/v sucrose in H2O) . A 15x20cm 1%-agarose gel was then run in TBE buffer (0.09 M Tris-borate, 0.002 M EDTA) using 8 μl of each reaction. The gel was run for approximately 16 hours at 45v. Gels were then stained in 20 μg/ml ethidium bromide for 1 hour and destamed m TBE buffer for approximately 3 hours. Polaroid photographs of the gels were then taken under UV illumination. The presence or absence of bands at specific sizes for each strain was scored from the photographs and entered as a similarity matrix in the numerical taxonomy software program, NTSYS-pc (Exeter Software, Setauket, NY) Controls of E. coli strain HB101 and Xanthomonas oryzae pv. oryzae assayed under the same conditions produced PCR fingerprints corresponding to published reports (Versalovic, J , Koeuth, T. and Lupski , J. R 1991. Nucleic Acids Res. 19, 6823-6831, Vera Cruz, C. M., Halda-Alija, L., Louws, F., Skinner, D. Z., George, M L., Nelson, R. J., DE Bruijn, F. J. , Rice, C. and Leach, J. E. 1995. Int. Rice Res. Notes, 20, 23-24.,- Vera Cruz, C. M., Ardales, E. Y., Skinner, D. Z., Talag, J , Nelson, R. J., Louws, F. J., Leung, H., Mew, T. W. and Leach, J. E. 1996. Phytopathology 86, 1352-1359) The data from Photorhabdus strains were then analyzed with a series of programs within NTSYS- pc; ΞIMQUAL (Similarity for Qualitative data) to generate a matrix of similarity coefficients (using the Jaccard coefficient) and SAHN (Sequential, Agglomerative, Heirarchical and Nested) clustering [using the UPGMA (Unweighted Pair-Group Method with Arithmetic Averages) method] which groups related strains and can be expressed as a phenogram (Fig. 7) . The COPH (cophenetic values) and MXCOMP (matrix comparison) programs were used to generate a cophenetic value matrix and compare the correlation between this and the original matrix upon which the clustering was based. A resulting normalized Mantel statistic (r) was generated which is a measure of the goodness of fit for a cluster analysis (r=0 8-0.9 represents a very good fit) In our case r=0.924. Therefore, the collection is comprised of a diverse group of easily distinguishable strains representative of the Photorhabdus genus -131- SUBSTΓΓUTE SHEET (RULE 26) Example 23 Insecticidal Utility of Toxm(s) Produced by Various Photorhabdus Strains Initial "storage" cultures of the various Photorhabdus strains were produced by inoculating 175 ml of 2% Proteose Peptone #3 (PP3) (Difco Laboratories, Detroit, MI) liquid medium with a primary variant colony in a 500 ml tribaffled flask with a Delong neck, covered with a Kaput closure. After inoculation, the flask was incubated for between 24-72 hrs at 28°C on a rotary shaker at 150 rpm, until stationary phase was reached. The culture was transferred to a sterile bottle containing a sterile magnetic stir bar and the culture was overlayered with sterile mineral oil, to limit exposure to air. The storage culture was kept in the dark, at room temperature. These cultures were then used as inoculum sources for the fermentation of each strain. "Seed" flasks or cultures were produced by either inoculating 2 mis of an oil overlayered storage culture or by transferring a primary variant colony into 175 ml sterile medium in a 500 ml tribaffled flask covered with a Kaput closure (The use of other inoculum sources is also possible.) Typically, following 16 hours incubation at 28°C on a rotary shaker at 150 rpm, the seed culture was transferred into production flasks Production flasks were usually inoculated by adding about 1% of the actively growing seed culture to sterile 2% PP3 medium (e.g 2.0 ml per 175 ml sterile medium) Production of broths occurred in 500 ml tribaffled flasks covered with a Kaput Production flasks were agitated at 28 °C on a rotary shaker at 150 rpm. Production fermentations were terminated after 24-72 hrs although successful fermentation is not confined to this time duration. Following appropriate incubation, the broths were dispensed into sterile 1.0 L polyethylene bottles, spun at 2600xg for 1 hr at 10°C and decanted from the cell and debris pellet. Further broth clarification was achieved with a tangential flow microflltration device (Pall Filtron, Northborough, MA) using a 0.5 μM open-channel poly-ether sulfone (PES) membrane filter. The resulting broths were then concentrated (up to 10-fold) using a 10,000 or 100,000 MW cut-off membrane, M12 ultra-flltration device (Amicon, Beverly MA) or centrifugal concentrators (Millipore, Bedford, MA and Pall Filtron, Northborough, MA) with a 13,000 or -132- SUBSTΓΓUTE SHEET (RULE 26) 100,000 MW pore size In the case of centrifugal concentrators, the broth was spun at 2000xg for approximately 2 hr The membrane permeate was added to the corresponding retentate to achieve the desired concentration of components greater than the pore size used. Following these procedures, the broth was used for biochemical analysis or filter sterilized using a 0.2 μM cellulose nitrate membrane filter for biological assessment Heat inactivation of processed broth samples was achieved by heating the samples at 100°C in a sand-filled heat block for 10 minutes The broth (s) and toxm complex(es) from different Photorhabdus strains are useful for reducing populations of insects and were used in a method of inhibiting an insect population which comprises applying to a locus of the insect an effective insect inactivating amount of the active described. A demonstration of the breadth of msecticidal activity observed from broths of a selected group of Photorhabdus strains fermented as described above is shown m Table 36. It is possible that improved or additional msecticidal activities could be detected with these strains through increased concentration of the broth or by employing different fermentation methods Consistent with the activity being associated with a protein, the msecticidal activity of all strains tested was heat labile . Culture broth (s) from diverse Photorhabdus strains show differential msecticidal activity (mortality and/or growth inhibition) against a number of insects. More specifically, the activity is seen against corn rootworm which is a member of the insect order Coleoptera Other members of the Coleoptera include boll weevils, wireworms, pollen beetles, flea beetles, seed beetles and Colorado potato beetle The broths and purified toxm complex (es) are also active against tobacco budworm, tobacco hornworm and European corn borer which are members of the order Lepidoptera. Other typical members of this order are beet armyworm, cabbage looper, black cutworm, corn earworm, codling moth, clothes moth, Indian mealmoth, leaf rollers, cabbage worm, cotton bollworm, bagworm, Eastern tent caterpillar, sod webworm and fall armyworm Activity is also observed against German cockroach which is a member of the order Dictyoptera (or Blattodea ) Other members of this order are oriental cockroach and American cockroach. -133- SUBSTΓΠJTE SHEET (RULE 26) Activity against corn rootworm larvae was tested as follows. Photorhabdus culture broth(s) (10 fold concentrated, filter sterilized), 2% Proteose Peptone #3 (10 fold concentrated), purified toxm complex(es), 10 mM sodium phosphate buffer, pH 7.0 were applied directly to the surface (about 1 5 cm 2 ) of artificial diet (Rose, R. I. and McCabe, J. M. 1973. J Econ Entomol 66, 398-400) in 40 μl aliquots. Toxm complex was diluted m 10 mM sodium phosphate buffer, pH 7.0 The diet plates were allowed to air-dry in a sterile flow-hood and the wells were infested with single, neonate Diabrotica undeeimpunetata howardi (Southern corn rootworm, SCR) hatched from surface sterilized eggs The plates were sealed, placed in a humidified growth chamber and maintained at 27°C for the appropriate period (3-5 days) Mortality and larval weight determinations were then scored Generally 16 insects per treatment were used all studies Control mortality was generally less than 5%. Activity against lepidopteran larvae was tested as follows Concentrated (10-fold) Photorhabdus culture broth(s) , control medium (2% Proteose Peptone #3), purified toxm complex(es), ιo mM sodium phosphate buffer, pH 7.0 were applied directly to the surface (about 1.5 cm 2 ) of standard artificial lepidopteran diet (Stoneville Yellow diet) in 40 μl aliquots. The diet plates were allowed to air-dry in a sterile flow-hood and each well was infested with a single, neonate larva. European corn borer [ Ostrima nubilalis) and tobacco hornworm [Manduca sexta) eggs were obtained from commercial sources and hatched m-house, whereas tobacco budworm [Heliothis virescens) larvae were supplied internally. Following infestation with larvae, the diet plates were sealed, placed m a humidified growth chamber and maintained the dark at 27°C for the appropriate period. Mortality and weight determinations were scored at day 5 Generally, 16 insects per treatment were used in all studies Control mortality generally ranged from about 0 to about 12.5% for control medium and was less than 10% for phosphate buffer. Activity against cockroach was tested as follows. Concentrated (10-fold) Photorhabdus culture broth(s) and control medium (2% Proteose Peptone #3) were applied directly to the surface (about 1.5 cm 2 ) of standard artificial lepidopteran diet (Stoneville Yellow diet) in 40 μl aliquots The diet plates were allowed to -134- SUBSTΓΠJTE SHEET (RULE 26) air-dry in a sterile flow-hood and each well was infested with a single, CO- anesthetized first instar German cockroach [ Blatella germanica) . Following infestation, the diet plates were sealed, placed in a humidified growth chamber and maintained in the dark at 27°C for the appropriate period. Mortality and weight determinations were scored at day 5. Control mortality less than 10%.

A 50 ml shake culture was produced in 175 ml baffled flasks m 2% proteose peptone #3 medium, grown at 28° and 150 rpm for approximately 24 hours. Fifteen ml of this culture were centrifuged (700 x g, 30 min) and frozen in its medium at -20° until it was thawed (slowly in ice water) for DNA isolation. The thawed W-14 culture was centrifuged (900 x g, 15 min 4°) , and the floating orange mucopolysaccharide material was removed. The remaining cell material was centrifuged (25,000 x g, 4°) to pellet the bacterial cells, and the medium was removed and discarded. Total DNA was isolated by an adaptation of the CTAB method described in section 2.4.1 of Ausubel et al . (1994). The modifications mcluded a high salt shock, and all volumes were increased ten-fold over the "miniprep" recommended volumes. All centrifugations were at 4°C unless otherwise specified. The pelleted bacterial cells were resuspended in TE buffer (10 mM Tris- HCl, 1 mM EDTA, pH 8) to a final volume of 10 ml, then 12 ml 5 M NaCl were added; this mixture was centrifuged 20 mm at 15,000 x g. The pellet was resuspended in 5.7 ml TE, and 300 μl of 10% SDS and 60 μl of 20 mg/ml proteinase K (in sterile distilled water, Gibco BRL Products, Grand Island, NY) were added to the suspension. The mixture was incubated at 37°C for 1 hr ; then approximately 10 mg lysozyme (Worthington Biochemical Corp., Freehold, NJ) were added. After an additional 45 min incubation, 1 ml of 5 M NaCl and 800 μl of CTAB/NaCl solution (10% w/v CTAB, 0.7 M NaCl) were added. This preparation was incubated 10 min at 65°C, then gently agitated and further incubated and agitated for approximately 20 min to assist clearing of the cellular material. An equal volume of chloroform/isoamyl alcohol solution (24:1, v:v) was added, mixed very gently, and the phases separated by centrifugation at 12,000 x g for 15 min. The upper (aqueous) phase was gently removed with a wide-bore pipette and extracted twice as above with an equal volume of PCI ( phenol/choloroform/ isoamyl alcohol; 50:49:1, v:v:v ; equilibrated with IM Tris-HCl, pH 8.0; Intermountam Scientific Corporation, Kaysville, UT) . The DNA precipitated with 0.6 volume of isopropanol was gently removed on a glass rod, washed twice with 70% ethanol, dried, and dissolved m 2 ml STE (10 mM Tris-HCl, 1 0 mM NaCl, 1 mM EDTA, pH 8 ) . This preparation contained 2 5 mg/ml DNA, as determined by optical density at 260nm. Identification of Bgl. II /Hind III Fragments Hybridizing to tc-gene Specific Probes Approximately 10 μg of genomic DNA was digested to completion with about 30 units each of Bgl II and Hmd III (NEB) for 180 mm, frozen overnight, then heated at 65°C for five mm, and electrophoresed m a 0.8% agarose gel (Seake " LE, IX TEA, 80 volts, 90 mm) The DNA was stained with ethidium bromide (50 μg/ml) as described earlier, and photographed under ultraviolet light. The DNA fragments m the agarose gel were subjected to depurmation (5 mm in 0.2 M HCl), denaturation (15 mm in 0.5 M NaOH, 1.5 M NaCl), and neutralization (15 mm in 0.5 M Tris HCl pH 8.0, 1.5 M NaCl), with 3 rinses of distilled water between each step The DNA was transferred by Southern blotting from the gel onto a NYTRAN nylon membrane (Amersham, Arlington Heights, IL) using a high salt (20X SSC) protocol, as described section 2.9 of Ausubel et al . (CPMB, op. cit.) The transferred DNA was then UV-crosslmked to the nylon membrane using a Stratagene UV Stratalmker set on auto crosslink. The membranes were stored dry at 25°C until use. Hybidization was performed using the ECL™dιrect (Amersham, Arlington Heights, IL) labeling and detection system following protocols provided by the manufacturer. In brief, probes were prepared by covalently linking the denatured DNA to the enzyme horseradish peroxidase. Once labeled the probe was used under hybridization conditions which maintain the enzymatic activity. Unhybridized probe was removed by two gentle washes 20 minutes each at 42°C in 0.5xSSC, 0.4% SDS, and 6M Urea. This was followed by two washes 5 minutes each at room temperature 2xSSC. As directed by the manufacturer, ECL™ reagents were used to detect the hybridizing DNA bands. There are several factors which influence the ability to detect gene relatedness between various Photorhabdus strains and strain W-14. First, high stringency conditions have not been employed in these hybridizations. It is known in the art that varying the stringency of hybridization and wash conditions will influence the pattern and intensity of hybridizing bands. Second, Southern blots' blot to blot variation will influence the mobility of hybridizing bands and molecular weight estamates. Therefore, W- 14 was included as a standard on all Southern blots. -138- SUBSTΓΓUTE SHEET (RULE 26) Gene specific probes derived from the W-14 toxin genes were used in these hybridizations. The following lists the specific coordinates within each gene sequence to which the probe corresponds. A probe specific for 1174 to 3642 of Sequence ID #25, a probe specific for tcaC: 3637 to 6005 of Sequence ID #25, a probe specific for tcbA: 2097 to 4964 of Sequence ID #11, and a probe specific for tcdA: 1660 to 4191 of sequence ID #46. The following tables summarize Southern Blot analyses of Photorhabdus strains. In the event that hybridization of probes occurred, the hybridized fragment (s) were noted as either identical or different from the pattern observed for the W-14 strain. -139- SUBSTTTUTE SHEET (RULE 26) Table, Southern Analysis of Photorhabdus Strains I = Identical fragment pattern; D = Different fragment pattern. -140- SUBSTΓΓUTE SHEET (RULE 26) Table ,39 Southern Analysis of Photorhabdus Strains = o e ermine ; = no e ec a e y ri iza ion product ; I = Identical fragment pattern; D = Different fragment pattern. + = Hybridization fragment pattern not determined. Table , 39 Southern Analysis of Photorhabdus Strains = o e ermine ; - = no e ec a e y ri iza ion produc ; I = Identical fragment pattern; D = Different fragment pattern. + = Hybridization fragment pattern not determined. From these analyses it is apparent that homologs of W-14 genes are dispersed throughout these diverse Photorhabdus strains, as evidenced by differences in gene fragment sizes between W-14 and the other strains . Example 25 N-Termmal Amino Acid Sequences of Tox Complex Peptides from Different Photorhabdus Strains The relationship of peptides isolated from different Pho torhabdus strains, as described in Example 14, were subjected to ■ 142- SUBSTΓΓUTE SHEET (RULE 26) N-termmal ammo acid sequencing. The N-terminal amino acid sequences of toxm peptides in several strains were compared to W- 14 toxin peptides. In Table 40, a comparison of toxin peptides compared to date showed that identical or homologous (at least 40% similarity to W14 gene/peptides ) tox peptides were present in all of the strains. For example, the N-terminal ammo acid sequence of TcaC, SEQ ID NO: 2, was found to be identical to that for 160 kDa peptide in HP88 but also homologs were present strains WIR, H9, Hb, WX-1, and Hm. Some W-14 peptides or homologs have not been observed other strains; however, not all peptides have Deen sequenced for toxm complexes from other strains due to N-terminal blockage or low abundance. In addition, many other N-termmal amino acid sequences (SEQ ID NOS: 82 to 88) have been obtained for tox complex peptides from other strains that have no similarity to peptides from W-14 and in some case were identical to each other. For example, an identical am o acid sequence, SEQ ID NO: 82, was obtained for 64 kDa peptide present in both HP88 and Hb strains and a homologous sequence for a 70 kDa peptide m NC-1 strain (SEQ ID NO: 83) .

Similar residues were identified as being a member in one of the following five groups: (P, A, G, S, T) ; (Q, N, E, B, D, Z); (H, K, R) ; , I, V, M) ; and (F, Y, W) . Example 26, immunological Analysis of Phot rh,a d s rains Culture broths of Photorhabdus strains were concentrated 10 to 15 times using Centrιprep-10 ultraflltration device (Amicon, Inc. Beverly, MA 01915) . The concentration of the protein ranges from 0.3 to 3.0 mg per ml Ten to 20 μg of total protein was loaded in each well of a precast 4-20% polyacrylamide gel (Integrated Separation Systems, Natic , MA 01760) . Gel electrophoresis was performed for 1.25 hours using a constant current set at 25 ma per gel. The gel was electro-blotted on to Hybond-ECL™ nitrocellulose membrane (Amersham Corporation, Arlington Hts, II 60005) using a semi-dry electro-blotter (Pharmacia Biotech Inc., Piscataway , NJ -144- SUBSTΓΓUTE SHEET (RULE 26) 08854) . A constant current was applied at 0.75 ma per cm for 2.5 hours. The membrane was blocked with 10% milk in TBST (25 mM Tris HCl pH 7.4, 136 mM NaCl, 2.7 mM KCl, 0.1% Tween 20) for one hour at room temperature. Each primary antibody was diluted in 10% milk/TBST to 1:500. Other dilution between 1:50 to 1.1000 was also used. The membrane was incubated in primary antibody for at least one hour. Then it was washed thoroughly with the blocking solution or TBST. A 1:2000 dilution of secondary antibodies (goat anti- mouse IgG or goat anti rabbit TgG conjugated to horseradish peroxidase; BioRad Laboratories, Hercules, CA 94547) 10% milk/TBST was applied to the membrane which was placed on a platform rocker for one hour. The membrane was subsequently washed with excess amount of TBST. The detection of the protein was performed by using an ECL (Enhanced Chemiluminescence) detection kit (Amersham International) . A panel of peptide speciflc-antibodies generated against W-14 peptides were used to characterize the protein composition of broths from nine non-W-14 Photorhabdus strains using Western blot analysis. In addition, one monoclonal antibody (MAb-C5F2) which recognizes TcbA 1L1 protein m W-14 -derived tox complex was used. The results (Table 39) showed cross recognition of the antibodies to some of the proteins in these broths. In some cases, the proteins that were recognized by the antibodies were the same size as the W-14 target peptides. In other cases, the proteins that were recognized by the antibodies were smaller than the W-14 target peptides. This data indicate that some of the non-W-14 Photorhabdus strains may produce similar proteins to the W-14 strain The difference could be due to deletion or protein processing or degradation process. Some of the strains did not contain protem(s) that could be recognized by some antibodies, however, it is possible that the concentration is significantly lower than those observed for W-14 peptides. When compared for various toxm peptide homologs these results showed peptide diversity among the Photorhabdus strains. -145- SUBSTΓΓUTE SHEET (RULE 26) Table 41 Cross Recognition by Monoclonal Antibodies or Polyclonal Antibodies Generated Against W-14 Peptides to Protein (s) in Broths of Selected Non-W-14 Photorhabdus Additional non-W-14 Photorhabdus strains were characterized by Western blot analysis using the culture broth and/or partial purified protein fractions as antigen. The panel of antibodies include MAb-C5F2, MAb-DEl (recognizing TcdA i:ι ), PAb-DE2 (recognizing TcaB), PAb-TcbA i:L -syn, PAb- TcaC-syn, PAb TcaB 11 -syn, PAb-TcbA i;Ll - syn, PAb-TcaB 1 -syn. These antibodies showed cross-reactivity with proteins in the broth and in the partial purified fractions of non- W-14 strains. The data indicate that antibodies could be used to identify proteins in the broth as well as in the partially purified protein fractions . -146- SUBSTΓΓUTE SHEET (RULE 25) Table 42 Cross Recognition by Monoclonal Antibodies or Plyclonal Antibodies Generated Against W-14 Peptides to Protein (s) Broths and/or Partial Purified Protein Fractions of Selected Non-W14 Photorhabdus Example 27 Bacterial Expression of the tcdA Coding Region Engineering of the tcdA Gene for Bacterial Expression The 5' and 3' ends of the tcdA coding region (SEQ ID NO.46) were modified to add useful cloning sites for inserting the segment into heterologous expression vectors. The ends were modified using unique primers m Polymerase Cham Reactions (PCR) , performed essentially as described Example 8. Primer sets, as described below, were used conjunction with cosmid 21D2 4 as template, to created products with the appropriately modified ends The first primer set was used to modify the 5' end of the gene, to insert a unique Neo I site at the initiator codon using the forward primer A0F1 (5' GAT CGA TCG ATC CAT GGC CAA CGA GTC TGT AAA AGA GAT ACC TGA TG TAT TAA AAA GCC AGT GTG 3 ' ) and to add unique Bgl II, Sal I and Not I sites to facilitate insertion of the remainder of the gene using the reverse primer A0R1 (5' GAT CGA TCG TAC GCG -147- SUBSTΓΓUTE SHEET (RULE 26) GCC GCT CGA TCG ATC GTC GAC CCA TTG ATT TGA GAT CTG GGC GGC GGG TAT CCA GAT AAT AAA CGG AGT CAC 3 ' ) . Another PCR reaction was designed to modify the 3 ' end of the gene by adding an additional stop codon and convenient restriction sites for cloning. The forward primer A0F2 (5' ACT GGC TGC GTG GTC GAC TGG CGG CGA TTT ACT 3') was used to amplify across a unique Sal I site in the gene, later used to clone the modified 3' end. The reverse primer A0R2 (5' CGA TGC ATG CTG CGG CCG CAG GCC TTC CTC GAG TCA TTA TTT AAT GGT GTA GCG AAT ATG CAA AAT 3 ' ) was used to insert a second stop codon (TGA) and cloning sites Xho I, Stu I and Not I . Bacterial expression vector pET27b (Novagen, Madison, WI) , was modified to delete the Bgl II site at position 446, according to standard molecular biology techniques. The 497 bp PCR product from the first amplification reaction (AOF1+AOR1) , to modify the 5 1 end of the gene, was ligated to the modified pET27b vector according to the supplier's instructions. The DNA sequences of the amplified portion of three isolates were determined using the supplier's recommended primers and the sequencing methods described previously The sequence of all isolates was the same. One isolate was then used as a cloning vector to insert the middle portion of the tcdA gene on a 6341 bp Bgl II to Sal I fragment. The resulting clone was called MC4 and contained all but the 3' most portion of the tcdA coding sequence. Finally, to complete the full-length coding region, the 832 bp PCR product from the second PCR amplification (AOF2+AOR2), to modify the 3' end of the gene, was ligated to isolate MC4 on a Sal I to Not I fragment, according to standard molecular biology techniques The tcdA coding region was sequenced and found to be complete, the resulting plasmid is called pDAB2035. Construction of Plasmids DDAB2036. pDAB2037 and pDAB2038 for Bacteria], Expression of tcd The tcdA coding region was cut from plasmid pDAB2035 with restriction enzymes Neo I and Xho I and gel purified. The fragment was ligated into the Neo I and Xho I sites of the expression vector pET15 to create plasmid pDAB2036 Additionally, pDAB2035 was cut with Neo I and Not I to release the tcdA coding region which was ligated into the Neo I and Not I sites of the expression vector pET28b to create plasmid pDAB2037 Finally, plasmid pDAB2035 was cut with Neo I and Stu J to release the tcdA coding region. This fragment was ligated into the expression vector Trc99a which was cut with Hind III followed by treatment with T4 DNA polymerase to blunt the ends. The vector was then cut with Neo I and ligated with the Wco I/Stu I cut tcdA fragment. The resulting plasmid is called pDAB2038. Expression of tcdA from Plasmid pDAB2038 Plasmid pDAB2038 was transformed into BL21 cells ana expressed as described above for plasmid pDAB2033 in Example 19. Purification of tcdA from E. coli The expression culture was centrifuged at 10,300 g for 30 mm and the supernatant was collected. It was diluted with two volumes of H2O and applied at a flow rate of 7.5 ml/min to a poros 50 HQ (Perspective Systems, MA) column (1.6 cm x 10 cm) which was pre- equilibrated with 10 mM sodium phosphate buffer, pH 7 0 (Buffer A) The column was washed with Buffer A until the optical density at 280 nm returned to baseline level The proteins bound to the column were then eluted with IM NaCl Buffer A. The fraction was loaded in 20 ml aliquots onto a gel filtration column, Sepharose CL-4B (2.6 x 100 cm), which was equilibrated with Buffer A. The protein was eluted in Buffer A at a flow rate of 0.75 mL/min. Fractions with a retention time between 260 minutes and 460 minutes were pooled and applied at 1 mL/min to a Mono Q 5/5 column which was equilibrated with 20 mM Tris-HCl, pH 7 0 (Buffer B) . The column was washed with Buffer B until the optical density at 280 nm returned to baseline level. The proteins bound to the column were eluted with a linear gradient of 0 to 1 M NaCl in Buffer B at lmL/min for 30 mm. One milliliter fractions were collected, serial diluted, and subjected to SCR bioassay Fractions eluted out between 0.1 and 0.3 M NaCl were found to have the highest msecticidal activity. Western analysis of the active fractions using pAb TcdA,, -syn antibody and pAb Tcd 111 -syn antibody indicated the presence of peptides TcdA,, and TcdA 111 . -149- SUBSTΓΓUTE SHEET (RULE 25) SEQUENCE LISTING (1) GENERAL INFORMATION: (l) APPLICANT: Ensign, Jerald C Bowen, David J Petell, James Fa ig, Raymond Schoonover, Sue ffrench-Constant, Richard Orr, Gregory L Merlo, Donald J Roberts , Jean L Rocheleau, Thomas A (ii) TITLE OF INVENTION: Insecticidal Protein Tox s from Photorhabdus (in) NUMBER OF SEQUENCES. 88 dv) CORRESPONDENCE ADDRESS: (A) ADDRESSEE.
