Description: Toxins from the wasp Bracon hebetor The present invention relates to novel insect toxins, DNA sequences encoding proteins which are toxic to insects, recombinant DNA constructs which comprise DNA sequences which encode a protein which is toxic to insects, and a biological control agent comprising said insect toxins, DNA sequences or recombinant DNA constructs. The venoms of many social wasps have been extensively studied and are known to contain a potent array of biologically active amines, pain-producing neuropeptides, allergens and neurotoxins (Piek (1991) Toxicon, 29, 139-149). Much less understood are the venoms of solitary wasps, especially those which lead a parasitic lifestyle. Many solitary parasitic wasps prey upon insects and more than 250 species have been observed to paralyse their host (for review see Piek and Spanjer (1986) Venoms of the Hymenoptera, T Piek (Ed.) Academic Press, London pp 161-307). Many of these species are in the family Braconidae. The majority of braconid wasps are primary parasites. Adults lay their eggs almost exclusively in or on other insects and, after hatching, the wasp larvae feed upon their host. One braconid species that has attracted attention is Bracon hebetor (Bracon = Microbracon = Habrobracoή). Bracon hebetor (B. hebetor) is a small (3 mm) parasite of Lepidoptera larvae which have a cryptic, or cocooning, lifestyle. Adult female wasps deposit eggs on the outside of host larvae while simultaneously injecting a paralysing venom. Within minutes, the host larvae become uncoordinated and eventually suffer complete paralysis. Although not directly fatal, this paralysis is permanent and immobilises the insect until the wasp larvae emerge to feed upon their host. The venom of B. hebetor possesses an extremely potent paralysing activity. In larvae of the greater waxmoth, Galleria mellonella (G. mellonella), it has been estimated that complete and permanent paralysis occurs at levels of 1 part venom to 200,000,000 parts host haemolypmph (Beard (1952) Conn. Agric. Exp. Stn. New Haven Bulletin, 562, 27). Furthermore, the venom shows selective toxicity towards insects and between insect orders. Spider, crayfish, frog, rat and guinea-pig neuromuscular preparations all appear to be insensitive to the venom (Rathmayer and Walther (1976) Animal, Plant and Microbial Toxins, 2, Plenum Press, New York, 299-307; Deitmer (1973) Die Wirkung des Griffes der Schlupf-wespe Habrobracon Say aufdie neuromuskulare Ubertragung am sartoriusmuskel des Frosches, Diplomarbeit, Universitat Bonn). The paralysing component of B. hebetor venom is thought to act by presynaptically blocking excitatory glutamatergic transmission at neuromuscular junctions, possibly by inhibiting the release of synaptic vesicles (Walther and Reinecke (1983) Neuroscience, 9, 213- 224; Piek and Mantel (1970) Comp. Gen. Pharmcol, 1, 87-92; Piek (1966) J. Insect Physiol, 12, 561-568). Venoms from many arthropods that prey on insects have been found to contain toxins which selectively act on insects. Such insect-selective neurotoxins can be important molecular tools to study insect neurobioiogy. The mode of action and insect-selectivity of B. hebetor toxin predicts that it could be useful in the study of neuromuscular transmission in Lepidoptera and in the study of vesicle release at Lepidopteran neuromuscular junctions. It will also be appreciated that such insect selectivity is very advantageous in the control of insect pests. However, since the published information on proteinaceous toxins from B. hebetor suggests that multiple toxins may exist it was first necessary to purify and characterise a toxin that had high neurotoxic activity to Lepidopteran larvae. We have now purified and characterised two neurotoxic proteins, which for ease of reference only have been designated bracon toxin 1 and 2 (hereinafter BrhTX-1, and BrhTX-2). Thus, according to one aspect of the present invention there is provided an insect toxin comprising four polypeptide subunits, wherein the polypeptide subunits have the N terminal amino acid sequences shown in Sequence ED Nos. 1, 2, 3 and 4. This insect toxin corresponds to BrhTX- 1. According to another aspect of the present invention there is provided an insect toxin obtainable from a parasitic wasp having estimated molecular weights of about 34,000 Da, about 21,000 Da, about 18,500 Da and about 17,000 Da as measured by an SDS- polyacrylamide gel electrophoresis method as defined herein. This insect toxin corresponds to the toxin designated BrhTX-2. We have also isolated and characterised the polypeptide subunits of at least BrhTX- 1. Thus according to another aspect of the present invention there is provided isolated DNA comprising the nucleic acid sequence as shown in Sequence ID No. 19; sequences which show 60% or more homology with the nucleic acid sequence as shown in Sequence ID No. 19; sequences which hybridise to the nucleic acid sequence as shown in Sequence ID No. 19; and sequences which are degenerate as a result of the genetic code to the nucleic acid as shown in Sequence ID No. 19 and encode the same polypeptide. According to yet another aspect of the present invention there is provided isolated DNA comprising the nucleic acid sequence as shown in Sequence ID No. 46; sequences which show 60% or more homology with the nucleic acid sequence as shown in Sequence ID No. 46; sequences which hybridise to the nucleic acid sequence as shown in Sequence ID No 46; and sequences which are degenerate as a result of genetic code to the nucleic acid as shown in Sequence ID No. 46 and encode the same polypeptide. According to a further aspect of the present invention there is provided isolated DNA comprising the nucleic acid sequence as shown in Sequence ID No. 57; sequences which show 60% or more homology with the nucleic acid sequence as shown in Sequence ID No. 57; sequences which hybridise to the nucleic acid sequence as shown in Sequence ID No. 57; and sequences which are degenerate as a result of the genetic code to the nucleic acid as shown in Sequence ID No. 57 and encode the same polypeptide. According to a yet further aspect of the present invention there is provided isolated DNA comprising the nucleic acid sequence as shown in Sequence ID No. 36; sequences which show 60% or more homology with the nucleic acid sequence as shown in Sequence ID No. 36; sequences which hybridise to the nucleic acid sequence as shown in Sequence ID No. 36; and sequences which are degenerate as a result of the genetic code to the nucleic acid as shown in Sequence ID No. 36 and encode the same polypeptide. The DNA of the present invention may be cDNA, genomic DNA or synthesised DNA. As mentioned above, the present invention includes DNA which shows 60% or more homology to the DNA sequences of the present invention. Preferably > 65%, more preferably > 70%, even more preferably ≥ 75% or ≥ 80% of the nucleotides are common. Especially preferred are sequences showing 85%, 90%, 95%, or 99% or more homology. The present invention also includes DNA which hybridises to the DNA of the present invention. Preferably such hybridisation occurs at, or between, low and high stringency conditions. In general terms, low stringency conditions can be defined as 3 x SCC at about ambient temperature to about 65°C, and high stringency conditions as 0.1 x SSC at about 65°C. SSC is the name of a buffer of 0.15M NaCl, 0.015M trisodium citrate. 3 x SSC is three times as strong as SSC and so on. The present invention further includes DNA which is degenerate as a result of the genetic code to the DNA of the present invention. According to another aspect of the present invention there is provided a polypeptide which is an insect toxin and which is substantially free from other proteins with which it is ordinarily associated, and which is coded for by any of the DNA of the present invention, including derivatives thereof. According to yet another aspect of the present invention there is provided a polypeptide having the amino acid sequence of any one of Sequence ID Nos. 20, 47, 58 or 37, including derivatives thereof. Preferably said amino acid derivative is a homologous variant, preferably having 80% or more common amino acids, more preferably 90% or more common amino acids. Preferably any changes are conservative amino acid changes. By conservative amino acid changes we mean replacing an amino acid from one of the amino acid groups, namely hydrophobic, polar, acidic or basic, with an amino acid from within the same group. An example of such a change is the replacement of valine by methionine and vice versa. The present invention also includes polypeptides which are translated from mRNAs arising from alternative splicing pathways for the primary transcription products derived from each of the cognate genes. The present invention further includes polypeptides which are produced by post-translational modification of the polypeptides of the present invention. Such post-translational modifications include peptide cleavage, addition of prosthetic groups, glycosylation or formation of multisubunit structures. The cDNAs of the present invention code for polypeptides which form the insect toxin of the present invention. The polypeptides of the present invention correspond to the subunits of the insect toxin of the present invention. In addition, each cDNA sequence of the present invention codes for a polypeptide which individually may provide an effect which is toxic to insects. Each of the polypeptides of the present invention may therefore provide an effect which is toxic to insects. According to further aspect of the present invention there is provided a recombinant DNA construct comprising a DNA sequence of the present invention. Such constructs include cloning vectors such as plasmids and phages suitable for transforming a cell of interest. According to another aspect of the present invention the recombinant DNA construct is an expression vector. The present invention includes any suitable constructs which are, or become, available. According to a yet further aspect of the present invention there is provided a transformed system comprising the recombinant construct of the present invention. Such systems include mammalian cells, non-mammalian vertebrate and invertebrate cells, insect cells, and plant cells. T e present invention also include bacteria, yeast, particularly fungi, and transformed with the recombinant constructs of the present invention, and viruses whose genomes have been directly or indirectly genetically manipulated to enable them to incorporate the DNA of the present invention. Suitable systems for transformation/genetic manipulation will be known to those skilled in the art. The method for producing such recombinant constructs/systems is not particularly germane to the present invention and any method suitable for the target may be used; such methods are known in the art. The DNA/toxins polypeptides of the present invention are obtainable from a parasitic wasp, such as from the superfamily Ichneumonidea. Preferably the toxin is obtainable from the family Braconidae. Examples of the family Braconidae are in the genera Apanteles, Bracon, Microbracon and Stenobracon. In an especially preferred embodiment the DNA/toxin/polypeptide is obtained from Bracon hebetor. The DNA/toxins polypeptides of the present invention may be obtained from other sources/via different routes, for example using conventional cloning techniques or synthetic methods. In a further aspect of the present invention there is provided a biological control agent comprising an insect toxin, polypeptide, recombinant DNA construct, or transformed system of the present invention. In this case the biological control agent preferably further includes an agronomically acceptable solid or liquid carrier. There is therefore provided a method of combating an insect pest in a habitat which comprises treating the pest or habitat with a pest-controlling effective amount of an insect toxin of the present invention. The present invention also includes biological control agents having a genome comprising nucleic acid of the present invention under the control of a promoter sequence which enables expression of said nucleic acid. Therefore included within the term biological control agent are viral, prokaryotic or eukaryotic organisms which when brought into association with an insect are capable of infecting the insect and interfering with the normal biochemical, physiological or electrophysiological processes and ultimately leading to the death of the insect. Suitable biological control agents within the scope of the invention include those based on bacterial, viral and fungal pathogens of insects. Bacterial pathogens include for example Bacillus species such as B. thuringiensis, B. cereus and the like. Fungal pathogens of insects include for example Beauvaria species such as B. bassiana. Alternatively the biological control agent can be a genetically modified plant endophyte in which the genome has been altered to incorporate at least one nucleic acid sequence of the present invention. When such an endophyte is brought into association with a plant the toxin coded for by the nucleic acid may be expressed by the endophyte within the plant and exert toxic effects on insects feeding on or dwelling within the plant. In a further variation the biological control agents can be a plant itself, particularly a crop plant being grown for food of fibre products, in which the plant genome has been modified by incorporation of at least one nucleic acid sequence of the present invention.

Example 1 - Isolation and Characterisation of BrhTX- 1 and BrhTX-2 Materials and Methods f i . Insects An established population of 5. hebetor (obtained from Dr R T Arbogast, USDA-ARS, P.O. Box 22909, Savannah, Georgia, USA) was reared on larvae of the Indian meal-moth (Plodia interpunctella) at 25°C with a photo-period of 16 hours light: 8 hours dark. Larvae of P. interpunctella and G. mellonella were obtained from an established population at the Commonwealth Scientific and Industrial Research Corporation, Division of Entomology, and raised at 25°C on a diet, for G. mellonella, composed of 600 g rice flour infant cereal, 60 g brewer's yeast, 125 ml honey and 125 ml glycerol and, for P. interpunctella, composed of 1000 g soyflour, 500 g bran, 250 g dried yeast, 250 g wheatgerm, 500 g cracked wheat, 500 g rolled oats and 375 g glycerol. (ii) Biological assays for toxin activity Paralysing activity in B. hebetor protein preparations was routinely determined using larvae of G. mellonella. The age and development status of the larvae used in bioassays was not determined; however, only larvae weighing between 0.15 g and 0.2 g were used. Biological assays were performed by injecting 10 μl of the protein sample, or control buffer, to be used between the prolegs into the haemocoel. Paralysis was scored if larvae did not move unless provoked and were unable to right themselves within 30 seconds after being placed on their back. Accurate monitoring of the toxin was facilitated by using end-point assays in which serial dilutions of a test extract were assayed for activity. Paralysing activity was measured using a modification of the Galleria Unit (GU) (Drenth (1974) Toxicon, 12, 198-192). The number of GUs in 10 μl of an injected extract was determined by taking the reciprocal of the extract dilution resulting in paralysis of larvae at approximately 2 hours post-injection. This value was then multiplied by 100 to obtain the number of GUs/ml extract, fiii. Extraction of venom gland components Female wasps were anaesthetised at 4°C and then kept on ice whilst their venom glands extracted by gently pulling on the ovipositor with fine forceps. Lots of 50 venom glands were extracted into 50 μl of iso-osmotic Pringle's saline (9 g 1 NaCl, 0.2 g 1 KC1, 0.2 g 1 CaCl2, 4 g 1 dextrose) made 0.02% with sodium azide and containing the proteinase inhibitors EDTA (ethylenediamine tctraacetic acid, disodium salt) (5mM), aprotinin (5mM), and pepstatin (0.1 μg/ml). The proteinase inhibitors were obtained from Boerhringer-Mannheim. The glands were homogenised by hand using a microhomogeniser and insoluble material was pelleted by centrifugation at 14,000 rpm for 5 minutes in an Eppendorf microfuge. The supernatant containing the toxin was then filtered through a 0.22 μm ultrafree-mC filter (Millipore, Bedford, MA). f iv) Protein determinations and concentration Protein content was determined with a protein assay kit obtained from Bio-Rad Laboratories using bovine serum albumin as standard. Protein samples were concentrated using Ultrafree-MC concentrating units (Millipore) following the manufacturer's recommendations. (v) Polvacrylamide gel electrophoresis and Anion Exchange Chromatography Polyacrylamide gel electrophoresis (hereinafter PAGE) equipment and reagents, PAGE and gel filtration standard protein mixes, and silver staining reagents were all purchased from Bio-Rad Laboratories. Denaturing SDS-polyacrylamide gel electrophoresis was performed as described by Laemmli (1970) Nature, 222, 680-685 using a 15% slab gel (11 cm x 14 cm x 0.075 cm) with a 4% stacking gel. Protein samples were made with 0.125 mM Tris-HCl [pH 6.8], 10% glycerol, 10% SDS (sodium dodecyl sulphate), 0.25% β-mercaptoethanol, 0.025% bromophenol blue, and heated at 95-100°C for 5 minutes before loading onto the gel. Proteins were fractionated at 200 volts until the bromophenol blue tracking dye reached the base of the gel (approximately 45 minutes). Proteins were detected by staining with either Coomassie Blue stain (obtained from Gradipore) for 2 hours followed by destaining in distilled water overnight or with silver stain. The molecular weights of the proteins were estimated by comparison with the molecular weights of the following standard proteins: rabbit muscle phosphorylase b (97,400 Da); bovine serum albumin (66,200 Da); ovalbumin (45,000 Da); bovine carbonic anhydrous (31,000 Da); soybean trypsin inhibitor (21,500 Da); lysozyme (14,400 Da). Non-denaturing native PAGE was carried out on 7.5% polyacrylamide slab gels (11 cm x 14 cm x 0.075 cm) with 4% stacking gels. Native gels were prepared in the same manner as the SDS-PAGE gels with the exception that SDS was not added to the gel or to the running buffers. Samples were made in 0.125 mM Tris-HCl [pH6.8], 10% glycerol, and were not heated before loading onto the gel. Electrophoresis was carried out at 200 volts for 1.5 hours at 4°C. Initial separation of soluble venom gland proteins was achieved using native-PAGE. Extracts of 600 venom glands were loaded onto each gel. Following electrophoresis the gels were horizontally sectioned into 4 mm strips and proteins were passively eluted from the gel slices with gentle shaking in 600 μl of 50 mM Tris-HCl [pH 8.0] for 16 hours at 4°C. An aliquot of each eluant was diluted 50-fold with 50 mM Tris-HCl [pH 8.0] and assayed for paralysing activity in G. mellonella as described above. Paralysing activity was further purified over an anion exchange column, namely Mini Q (PC, 3.2 mm x 3 cm, Pharmacia) using the SMART chromatography system (Pharmacia). Native-PAGE eluants containing paralysing activity were passed through 0.22 μm filters (Millipore) before loading onto the column. The column was equilibrated with 50 mM Tris-HCl [pH 8.0] and proteins were eluted at a flow rate of 200 μl/min using a linear gradient of 0 to 1 M NaCl. Proteins eluted from the column were detected by monitoring the absorbance of the eluant at 280 nm. Fractions of 200 μl were collected and assayed for paralysing activity. Fractions with paralysing activity were further analysed by SDS-PAGE. (vi) Gel-filtration chromatography To estimate the molecular mass of the native paralysing toxin, 50 μl of native-PAGE eluants containing paralysing activity were applied to a gel-filtration column, namely Superose 12 (PC, 3.2 mm x 30 cm, Pharmacia) that had been previously calibrated with the following standard proteins: thyroglobulin (670,000 Da); gamma globulin (158,000 Da); ovalbumin (44,400 Da); myoglobin (17,000 Da); vitamin B12 (1,350 Da). The column was pre-equilibrated with 50 mM Tris-HCl [pH 8.0], 150 mM NaCl and the protein eluted in the same buffer at a flow rate of 40 μl/min. Protein eluted from the column was detected by monitoring the absorbance of the eluant at 280 nm. Fractions of 40μl were collected and diluted 20-fold with 50 mM Tris-HCl [pH 8.0] before being assayed for paralysing activity. Results fi. Selection of starting material Due to the small size of the adult B hebetor (2-3 mm) and the corresponding minute size of the venom gland, we initially examined whether whole wasps or isolated venom glands would provide the most appropriate starting material for isolation of the neurotoxin. Three preparations of 25 whole females or isolated venom glands were analysed for protein content and paralysing activity (GUs). The results show that both preparations possess comparable toxic activity (approximately 25,000 GUs) but that extracts of whole female wasps have a 10-fold higher concentration of soluble protein than extracts of isolated venom glands as shown below in Table 1. This demonstrates two important points: observed neurotoxic activity is associated with soluble venom glands components; and venom gland extracts provide a 10-fold enrichment of neurotoxin. Glands were used as the starting material for the purification of the neurotoxin. Table 1 * 'Values are the result (± standard deviation) of 3 lots of preparations each of 25 wasps or venom glands. (ϋ) Polyacrylamide gel electrophoresis and Anion exchange chromatography Soluble venom gland extracts were first separated by native-PAGE. Following electrophoresis the gel was sectioned horizontally into 4 mm slices and each slice placed in buffer to recover the proteins by passive elution. Neurotoxic activity was generally quite diffuse and found in a large portion of the gel. However, end-point analysis revealed that after a 2 hour electrophoresis time activity was predominantly located in the first 2-3 cm of the gel. Toxin recovered from this region of the gel was subsequently termed B- 1. Toxic activity did not migrate significantly further even after extended electrophoresis times of 3-4 hours. Larvae of G. mellonella injected with recovered toxin showed intoxication symptoms consistent with neuromuscular paralysis. No skeletal muscle activity was observed; however, mouth parts were visibly active and excreta was released. Occasionally, a second paralysing activity, subsequently termed B-2, was observed which migrated slightly faster than B- 1. Since the two activities were often found in non-adjacent gel slices and could be completely resolved, they were considered to be distinct and separate activities. Native-PAGE fractionation provided a 90-fold enrichment of B- 1 neurotoxic activity from whole wasps, as shown below in Table 2, and an overall recovery of toxic activity of 41%. T bie 2' 'Values were obtained from 3 different lots of 300 venom glands separated using native - PAGE. Native-PAGE preparations were then pooled for anion exchange chromatography and the protein and toxin unit values divided by 3 for the purpose of comparison. b Mean ± standard error of the mean c Value based on comparison between whole female wasp and venom gland extract (see Table 1). The separation of venom gland extracts, B-l and B-2 using SDS-PAGE is shown in Figure 1. In Figure 1, Lane 1 corresponds to venom gland extract; Lane 2 to Native-PAGE purified B-l; Lane 3 to Native-Page purified B-2; Lane 4 to anion exchange purified BrhTX- 1 (approximately 1 μg); Lane 5 to anion exchange purified BrhTX- 2 (approximately 3 μg); and Lane 6 to molecular weight markers. Although the protein profile is still complex, specific enrichment of polypeptide bands with molecular weights of approximately 22,000 Da, 18,000 Da, 17,000 Da and 16,000 Da is seen. In a final purification step, B-l and B-2 were further fractionated using anion-exchange chromatography. When passed separately over the column, each activity eluted at approximately 200 mM NaCl and was confined to a single fraction that correlated with one distinct chromatographic peak as shown in Figure 2 for B- 1 , which shows the chromatograph for native-PAGE eluants (400 μl) containing B-l loaded onto the column. All paralysing activity was found in fraction No. 9. Biological assay of collected fractions revealed that all measurable paralysing activity of both B-l and B-2 was present in this single fraction. The combination of native-PAGE and anion-exchange chromatography purified B-l activity 126-fold from whole wasps with an overall recovery of 7% of starting toxic activity. Analysis of anion-exchange purified B-l and B-2 using SDS-PAGE under reducing conditions shows that both activities appear similar and both resolve into four polypeptides, hereinafter referred to as subunits BrhTX- 1(a), BrhTX- 1(b), BrhTX- 1(c) and BrhTX- 1(d) for B-l, and subunits BrhTX-2(e), BrhTX-2(f), BrhTX-2(g) and BrhTX-2(h) for B-2. The purified toxins were named bracon toxin- 1 (BrhTX- 1) and bracon toxin-2 (BrhTX-2). At this stage of the purification BrhTX- 1 corresponded to approximately 0.5% of the soluble protein from venom gland extracts. More particularly, these techniques indicate that the polypeptides BrhTX- 1(a), BrhTX- 1(b), BrhTX- 1(c) and BrhTX- 1(d) of BrhTX- 1 have estimated molecular weights of 15,000 Da, 17,000 Da, 21,000 Da and 34,000 Da respectively. The polypeptides BrhTX-2(e), BrhTX-2(f), BrhTX-2(g) and BrhTX-2(h) of BrhTX-2 have estimated molecular weights of 17,000 Da, 18,500 Da, 21,000 Da and 34,000 Da respectively. fiii. Gel-filtration chromatofrraphv The predicted molecular weight of BrhTX- 1 and BrhTX-2 calculated from the four polypeptides resolved using SDS-PAGE is 87,000 Da and 90,500 Da respectively. In order to determine the native molecular mass of BrhTX- 1 and BrhTX-2, native-PAGE fractions were separated on a Superose 12 gel-filtration column. The majority of toxic activity eluted in two fractions that corresponded to a single major peak on the chromatogram. The results for BrhTX- 1 are shown in Figure 3, which shows a size-fractionation chromatography of BrhTX- 1; the hatched peak respresenting the fractions containing paralysing activity. Using a standard curve derived from the protein standards used to calibrate the column, the native toxin of BrhTX- 1 was calculated to have a molecular weight of approximately 81 ,000 Da, as shown in Figure 4. More particularly, a __.„ for each standard was calculated and plotted against the molecular weight of the protein. Using the K, v for toxic activity and the slope and intercept of the regression line 0^=0.98) for the standards, the molecular weight of the paralysing activity was calculated. BrhTX-2 was also calculated to be approximately 81,000 Da. ■ iv. Analysis of the secondary structure of BrhTX- 1 The secondary structure of BrhTX- 1 was investigated using SDS-PAGE under non-reducing and reducing conditions. The results are shown in Figure 5, in which Lane 1 correspond to BrhTX- 1 fractionated using SDS-PAGE in the absence of reducing agents; and Lane 2 corresponds to an identical sample run on Lane 1 that has been exposed to 3% β- mercaptoethanol. As show in Figure 5, migration of the polypeptides (a) and (b) are not significantly effected by the presence or absence of reducing agent, although under non-reducing conditions the polypeptide (b) appears to be present as a doublet. In contrast, under non-reducing conditions, the polypeptides (c) and (d) are not visible and an apparent novel polypeptide of approximately 45,000 Da appears. Conversely, this band resolves into two polypeptides of 34,000 Da and 21,000 Da when re-fractionated using SDS-PAGE under reducing conditions (data not shown). This suggests that polypeptides (c) and (d) are cross linked with intra- or inter-molecular disulphide bonds. This is of particular interest since earlier studies such as Visser et al., (1983) Comp. Biochem. Physioi, B75B, 523-538 have shown that B. hebetor paralysing activity is lost when venom is exposed to the reducing agents DTT and BME. Discussion Quantitative studies of extracts of 25 venom glands and 25 whole female wasps revealed that each contained, on average, 13,500 units of paralysing activity (GUs). This supports the assumption that the toxic activity identified in the G. mellonella bioassay is associated with soluble venom gland contents. To purify the paralysing agent, venom gland extracts where first fractionated using native-PAGE. Toxic activity did not migrate rapidly under the electrophoresis conditions used. Since native-PAGE separates by charge as well as size, this suggests that toxic activity has either an overall basic charge and/or a high molecular weight. The separation of two distinct activities (B-l and B-2) that appear to differ in molecular weight by only 3,500 Da indicates that charge is the major contributing factor to the rate of the toxin's migration. Anion-exchange chromatography of B-l yielded a single protein. This purified preparation (BrhTX- 1) represented 7% of the starting paralysing activity present in extracts of venom glands and presumably whole female wasps and 0.5% of soluble venom gland proteins. The overall enrichment of toxic activity is 127-fold and yields a preparation with a specific activity of 3,333 units of toxic activity per μg of protein. The data reported here provide evidence that we have purified two oligomeric toxins, BrhTX- 1 and BrhTX-2, which do not dissociate under native-PAGE or mild chromatographic conditions. Both toxins are composed of four polypeptides that can be separated using SDS- PAGE. Furthermore, separation of BrhTX- 1 using SDS-PAGE under reducing and non-reducing conditions suggests that two of the subunits, BrhTX- 1(c) and BrhTX- 1(d), are held with a disulphide bond. Example 2 - Sequence Analysis of BrhTX- 1 (i) Protein Purification 45,000 glands were purified using native-PAGE and anion exchange chromatography on the SMART system to yield 300μg of BrhTX- 1. The toxin was essentially homogeneous when analysed using SDS-PAGE followed by silver staining and composed of four polypeptides - BrhTX- 1(a), BrhTX- 1(b), BrhTX- 1(c) and BrhTX- 1(d). The specific activity of the final preparation was 3,250,000 GUs/mg protein. Furthermore, with this data it can be estimated that 0.3 ng of purified toxin can completely paralyse G. mellonella larvae weighing 0.2 g. The specific activity value also permits comparison of the toxin to the toxin from the straw-itch mite (Pyemotes triticϊ). The reported paralysis dose of the straw-itch mite toxin is 330-550μg/kg G. mellonella larvae. BrhTX- 1 has a paralysis dose of approximately 2μg/kg G. mellonella larvae. BrhTX- 1 was found to be very stable at 4°C, and even after several weeks over 90% of the activity was still present, (ϋ. Sequence Analysis Approximately 200 μg of BrhTX- 1 toxin was separated into its subunits using SDS-PAGE followed by electro-transfer in 10 mM Caps (zwitterionic buffer) [pH 11.0]/10% methanol at 60 mAmps for 1 hour at room temperature. The separated subunits were electroblotted onto PVDF (polyvinylidine fluorine) membrane. Following the transfer the blot was washed in Milli-Q water for 1 hour and then dried under vacuum. Protein bands were visualised by staining for approximately 30 seconds in 0.0005% sulforhodamine B (obtainable from Sigma) in 30% methanol 0.2% acetic acid followed by destaining in water. Small amounts of toxin, about lOμg, were initially used to optimise the blotting conditions after which 150 μg of toxin was prepared for sequence analysis. Sequencing was carried out using an ABI 477A protein sequencing system (from Applied Biosystems). Problems were encountered during the sequencing of BrhTX- 1(a), BrhTX- 1 (b) and BrhTX- 1 (c); notably, after 2 or 3 cycles, a clearly detectable signal from the amino acid analyser would disappear, indicating that much of the protein was being removed from the membrane during the sequencing process. This problem was overcome by applying greater concentrations of protein to the membrane. Amino-terminal sequence of all four subunits was obtained as shown in Figure 6 (""indicates amino acid residues where there was some ambiguity in the identity of the amino acid sequence). This sequence information is also shown in Sequence ID No. 1 for subunit BrhTX- 1(a); Sequence ID No. 2 for subunit BrhTX- 1(b); Sequence ID No. 3 for subunit BrhTX- 1(c); and Sequence ED No. 4 for subunit BrhTX- 1(d). (iii. Subunit Structure Studies Toxic activity was found to be associated with a small polypeptide from BrhTX- 1 of between 14,000 Da and 18,000 Da that had been isolated using native-PAGE containing Triton X-100. From such gels we recovered about 1,500 GUs from the total of about 30,000 that had been loaded. Although this represents only about 5% of the total activity loaded onto the gel, a substantial amount of the activity migrates only a small way into the gel. These results illustrate that the subunit has substantial activity, f iv . Western Blot Analyses Antibodies were generated against the BrhTX- 1(a), BrhTX- 1(c), BrhTX- 1(d) subunits by utilising the N-terminal sequence (Figure 6 and Sequence ID Nos. 1,3 and 4 respectively) made available by the direct protein sequencing described above. These antibodies were generated commercially by Chiron Mimitopes (Clayton, Victoria) as outlined below. Synthetic peptides were generated to match the available sequence and linked to a diphtheria toxin carrier. These conjugates were then used to immunise three separate New Zealand White rabbits. Rabbits were immunised intramuscularly with 0.39 mg of the peptide in Freund's Complete Adjuvent. After completion of the first immunisation, the rabbits were exsanguinated from an ear vein using a cannula and then exsanguinated again at days 14, 35 and 42. Serum was prepared by incubating the blood at 37°C for 30 minutes and then chilling on ice for 15 hours prior to removal of cellular material by low-speed centrifugation. The serum was stored at -20°C. All crude antisera were titrated in ELISA against a biotinylated derivative of the immunising peptide, diphtheria toxin and avidin. In these titration experiments the ELISA plate was coated with avidin, to which the biotinylated peptide and the antibody being tested were sequentially bound. Quantification of the antibody was then achieved using an anti-rabbit IgG serum linked to horseradish peroxidase. Using the highest titred sera against each of the subunits, Western blots were carried out against purified BrhTX- 1 separated into its constituent subunits by SDS-PAGE as previously described. After electrophoresis proteins were transferred to nitrocellulose (Biorad, Hercules, Ca). Using 10 μl of purified BrhTX- 1 (approximately (8 μg), separated by SDS-PAGE, a specific reaction was obtained against the relevant subunit of all three sera tested. . v. Peptide/Digestion Sequencing Approximately 800 μg of BrhTX- 1 was separated into its consistuent subunits by SDS- PAGE as previously described. After electrophoresis the subunits were visuaUsed in the gel by staining with Coomassie Brilliant Blue. Bands corresponding to each of the subunits were then excised from the gel and the SDS eluted from the gel by washing twice in buffer containing 0.2M ammonium bicarbonate, 0.02% Tween-20. Then 0.5 μg of sequencing grade trypsin (Promega, Madison, WI) was added and the gel fully rehydrated by the addition of approximately 20 μl of 0.2M ammonium bicarbonate. The gel slice was then transferred into a microfuge tube and covered with 0.2M ammonium bicarbonate, 0.02% Tween-20 and incubated at 30°C overnight. The reaction was stopped by the addition of one tenth volume of 10% w/v trifluoroacetic acid. After digestion, the resulting peptides were eluted from the gel by extraction for 40 minutes in 100 μl of 0.1% w/v trifluoroacetic acid in 60% acetonitrile at 30°C. The resultant supernatant was then reduced to a final volume of 20 μl by rotary evaporation (Hetovac (Heto) Scandinavia). The peptides were then separated by reverse phase chromatography on a SMART system using a μRPC C2/C18 SC2.1 1/10 column. Gradients over this column were formed by using the buffers 0.065% trifluoroacetic acid and 0.05% trifluoroacetic acid in 40% acetonitrile. Fractions were collected using the "Peak Fractionation" function. Individual peaks from this chromatography step were then subjected to mass spectroscopy (Tofspec, Fisons Instruments) to ascertain the size of the recovered peptides. Peaks were then sequenced using a Procise-HT sequencer (Applied Biosystems). A summary of the tryptic fragment sequence obtained from the subunits of BrhTX- 1 is given below in Table 3. Table 3 Where there were ambiguities in the sequence obtained the possible options are shown in brackets separated by a slash (/). Example 3 - Cloning of Subunits of BrhTX- 1 Generation of cDNA Library and Library Plating Total RNA was isolated from newly emerged female B. Hebetor, which had been frozen in liquid nitrogen and stored at -70 °C. To isolate total RNA, approximately 1 g of frozen wasps were ground to powder in liquid nitrogen. The powder was further homogenised in a hand-held homogeniser in 20 ml of 8M guanidinium chloride. Large fragments of insoluble material were removed by centrifugation at 10,000 x g for 10 minutes and total RNA was precipitated in the presence of 32% v/v ethanol. Subsequent purification of the total RNA was then carried out as described in Sambrook et al., (1989) Molecular Cloning: A Laboratory Manual, Cold Spring Habor Press. mRNA was isolated from total RNA using oligo (dT)-cellulose spin columns obtained from Pharmacia Biotech (Uppsala, Sweden) as per the manufacturer's instructions. Approximately 5 μg of mRNA was used for the cDNA synthesis. Eco K Not I linkers were ligated onto the blunt ended double stranded cDNA, ligated into Eco RI digested λgtl 1 DNA, and transformed into commercially available E coli Y1090, and subsequently amplified using standard techniques. Titling was carried out prior to screening of the library by standard methods (Sambrook 1989) using plating cells prepared from the commercially available E coli LE392 strain.. The titre of the library was 1.25xl0 9 pfu/ml. For screening 500,000 pfu were plated-out on ten 140 mm Petri dishes with approximately 50,000 plaques per plate. Plaque lifts were done in triplicate on to Hybond-N membranes (Amersham International) using standard methods (Sambrook 1989). Example 4 - Cloning of subunit (a) of BrhTX- 1 (i . Generation of Probes Three pools of degenerate oligonucleotides, designated BH(a)A, BH(a)B and BH(a)I, which code for at least part of the N-terminal sequence of BrhTX- 1(a), were designed. Inosines, represented by \ were used where there was full degeneracy. These oligonucleotides are shown in Figure 7 and also Sequence ID Nos. 5, 6 and 7 (where isosine is represented by "N"). The oligonucleotides were synthesised by standard methods on an Applied Biosystems 380B DNA synthesiser. Each oligonucleotide was deprotected for 16 hours at 55°C then divided into three screw-cap polypropylene microcentrifuge tubes and dried-down under vacuum. One third of each oligonucleotide was dissolved in 100 μl H2O and quantified by UV spectroscopy, 1 OD26()/ml equivalent to 25 μg/ml. (ii . Screening of library and Isolation of Clones Each set of filters was probed with one of the oligonucleotides, either BH(a)A, BH(a)B or BH(a)I. 25 ng of each oligonucleotide was labelled by 5' phosphorylation with 3 p_ATP (Amersham International) and T4 polynucleotide kinase (Northumbria Biologicals Ltd) using standard methods (Sambrook 1989). Incubation was 30 minutes at 37°C. Filters were prehybridised for 2 hours at 45°C in 5 x SSPE (20 x SSPE: 3.6 M NaCl, 0.2 M NaH 2 PO 4 , 0.02 M EDTA [pH7.7]), 5 x Denhardt's Reagent [50 x Denhardt's Reagent: 5 g Ficoll (Type 400, Pharmacia), 5 g polyvinylpyrrolidone, 5 g bovine serum albumin (Fraction V, Sigma)], 0.5% SDS and 200 μg/ml salmon sperm DNA. Hybridisation was carried-out in 5 x SSPE, 5 x Denhardt's Reagent, 0.5% SDS plus labelled probe at 45°C for 16 hours. Filters were washed in 6 x SSC, 0.1 % SDS at 45°C for 4 x 15 minutes and then exposed to Kodak X-AR film, with intensifying screens, at -80°C. Three plaques hybridised to both BH(a)A and BH(a)I, one plaque hybridised to both BH(a)B and BH(a)I. No plaques hybridised to all three probes. After three subsequent rounds of plaque purification, three of the four plaques had been purified to homogeneity and continued to display hybridisation to BH(a)I. Phage plaques were picked into 1 ml SM buffer (50 mM Tris-HCl [ρH7.5], 0.1 M NaCl, 0.2% (w/v) MgSO 4 .7H2θ, 0.01% (w/v) gelatin) plus lOμl chloroform. fiii. Characterisation of Clones The plaque-purified phage were screened for the presence and size of a cDNA insert by polymerase chain reaction (hereinafter PCR) analysis. Two oligonucleotides, λgt 11 forward and λgt 11 reverse, were used, as shown below and in Sequence ID Nos. 8 and 9 respectively. These oligonucleotides are specific for λgt 11 and flank the Eco RI cloning site, λgt 11 forward 5'-GACTCCTGGAGCCCG-3' λgt 11 reverse S'-TTGACACCAGACCAACTGGTAATG-S' The PCR reactions were carried out in 0.5 ml polypropylene microcentrifuge tubes using 25 mole of each concentrated primer, 0.5 μl phage stock, 8 μl Ultrapure dNTPs (Pharmacia) 1.23 mM of each, 2.5μl 500 mM KCl, 100 mM Tris [pH8.4], 15 mM MgCl 2 , 0.1% (w/v) gelatin and 0.2 μl (1U) Taq DNA polymerase (Perkin/Elmer Cetus). One drop of light mineral oil (Sigma) was added. The tubes were placed in a Techne PHC-1 Programmable Dri-block and subjected to the following temperature regime: 5 seconds at 94°C; 1 second at 94°C; 2 seconds at 40°C; 3 seconds at 72°C (35 cycles) followed by a final incubation period of 7 seconds at 72 °C . 10 μl of each reaction was analysed by agarose gel electrophoresis. All 3 phage stocks generated a PCR amplification fragment which indicated the following cDNA insert sizes: λBrhTX- 1(a) 1.1 - about 600 base pairs (bp); λBrhTX- 1 (a) 1.2 - about 620 bp; and λBrhTX-l(a)1.3 - about 590 bp. fiv) Subcloning and Sequencing of Clones Phage DNA preparations were carried-out using the method of Grossberger D (1987) Nucleic Acid Research, 15(10), 6737. The cDNA inserts were released from λBrhTX-1 (a) 1.1 and λBrhTX- 1 (a) 1.2 by Eco RI digestion. The insert from λBrhTX- 1 (a) 1.3 was not released which probably indicates that the Eco RI sites had not been recreated during the original library construction. The two released inserts were each ligated into Eco RI digested, phosphatase treated plasmid pUC19 with T4 DNA ligase in appropriate buffer conditions (Sambrook 1989). The ligation mixtures were used to transform competent commercially available E coli DH5α cells under standard conditions (Sambrook 1989). Transformants, designated pBrhTX- 1 (a) 1.1 and pBrhTX- 1 (a) 1.2, were selected on LB agar plates containing 100 μg ml ampicillin. The insert of clone pBrhTX- 1(a) 1.1 was sequenced using a Sequenase kit (USB, Cleveland, Ohio) and nine synthetic oligo primers, as shown below and in Sequence ID Nos. 10 to 18.

The other primers were designed using the sequence data generated by the initial PUC4 and PUC1 sequencing runs. The nucleotide sequence obtained is shown in Sequence ID No. 19. Translation of the nucleotide sequence gave an open reading frame (hereinafter ORF) of 125 amino acids. This deduced amino acid sequence is given in Sequence ID No. 20. Amino acids 17-36 correspond to the N-terminal sequence of subunit (a) as shown in Sequence ID No 1. Amino acids 1 to 16 have the features of a signal sequence for protein export. This nucleic acid sequence and corresponding amino acid sequence is also shown in Figure 8. (v) Analysis of Clones Peptide Digestion/Sequencing - The alignment of the sequences obtained using the peptide digestion method against the deduced amino acid translations from the cDNA is shown below: Peptide Sequence FNPETHR cDNA Sequence FNPETHR Peptide Sequence EAYIQNHGA cDNA Sequence EACIQNHGA The apparent anomaly in the second alignment can be explained by the fact that detection of cysteine can be unreliable. Genomic Southern Blot - Genomic DNA was prepared from male and female B. hebetor adults by the following method. Approximately 0.1 g of frozen wasps are gently homogenised in 500 μl of Lifton Solution (0.2M sucrose, 0.05M EDTA, 0.5M SDS, 0.1M Tris-HCl pH 9.0). When most of the material is broken up a further 500 μl of Lifton Solution is added and the homogenate is agitated until the tissue ceases to aggregate. The homogenate is then incubated at 65°C for 30 minutes before the addition of 250 μl of 0.6M acetate. This solution is then gently mixed and left on ice for 1 hour. Large paniculate matter is then removed by centrifugation at 4°C in a bench-top centrifuge for 10 minutes at 10,000 rpm. The supernatant is then extracted sequentially with equal volumes of phenol (saturated with TE), phenol/chloroform:isoamyl alcohol (24:1) (IAC) and lAC. RNAse A is then added to a final concentration of 10 μg ml and incubated at 37°C for 15 minutes. Two volumes of ethanol are then added to the solution and the DNA precipitated by centrifugation at room temperature for 15 minutes at 8,000 rpm in a bench-top centrifuge. After washing the precipitated DNA with 80% ethanol and drying, the DNA is resuspended in 50 μl of TE and the concentration of DNA estimated spectrophotometrically. The purified DNA was digested with the following restriction enzymes: Pst I, Bel I, Ace I, and the fragments separated by electrophoresis in a 0.7% agarose gel in TAE buffer. DNA was blotted onto Hybond C " (Amersham International) nitrocellulose membrane in a 20 x 2 x SSC gradient and bonded to the membrane by baking at 80 °C for 4 hours. 32 P-labelled cDNA probes were synthesised by PCR using the primers BH(a)Rl and BH(a)R3 and the plasmid clone pBrhTX- 1(a) 1.1 as target DNA. The probes were generated using the following PCR conditions: 5 minutes at 95°C; then 30 seconds at 95°C; 1.5 minutes at 45°C; 1 minute at 72°C (5 cycles); then 30 seconds at 95°C; 1.5 minutes at 50C; 1 minute at 72°C (5 cycles); then 5 minutes at 72°C. Pre-hybridisation and hybridisation were carried out under the following conditions: Pre-hybridisation - Two hours at 42°C in pre-hybridising solution containing 6 x SSC, 5 x Denhardt's Reagent, 0.5% SDS, 50% formamide, 0.1% sodium pyrophosphate and 100 μg/ml salmon sperm DNA (sonicated and boiled prior to addition). Hybridisation - overnight at 42°C in pre-hybridising solution to which 32 P-labelled probe had been added. The probe was boiled and then cooled rapidly on ice before addition to the filter and the pre-hybridising solution. After hybridisation the filters were washed four times in 2 x SSC, 0.1% SDS at 42°C. Each wash was carried out for 15 minutes. After washing the filters were blotted, wrapped in cling-film and exposed to Fuji medical film. The results indicate only a single copy of the sequence is present in the genome: (1) a digest of the genomic DNA using Pst I gave a single hybridising fragment of about 3040 bp; (2) a digest using Bel I gave a single hybridising fragment of 1400 bp (there is a Bel I site present in the cDNA sequence immediately after the probe-hybridising sequence); and (3) a digest using Ace I gave two hybridising fragments that are consistent with the presence of an Ace I site at 357 bp in the cDNA sequence (see Figure 8). Example 5 - Cloning of subunit (d) of BrhTX- 1 (ϊ) Generation of Prohes Three pools of degenerate oligomers were designed, BH(d)A, BH(d)B and BH(d)I. Inosines were used were there was full degeneracy. These oligonucleotides are as shown in Figure 9 and Sequence ID Nos. 21, 22 and 23. These oligonucleotides were synthesised by standard methods on an Applied Biosystems 380B DNA synthesiser. Each oligonucleotide was deprotected for 16 hours at 55°C then divided into two screw-cap polypropylene microcentrifuge tubes and dried-down under vacuum. One half of each oligonucleotide was dissolved in lOOμl water and quantified by UV spectroscopy, 1 OO2Qτy''T- equivalent to 25 μg/ml. (») Screening of library and Isolation of Clones The library was screened using the protocol described above for subunit BrhTX- 1(a). Seven plaques hybridised to BH(d)I. After three subsequent rounds of plaque purification, six plaques had been purified to homogeneity and continued to display hybridisation to BH(d)I. Phage plaques were picked into 1ml SM buffer and lOμl chloroform, fiii. Characterisation of Clones The plaque-purified phage was screened and analysed using the protocol described above for subunit BrhTX- 1(a). Five of the six phage stocks generated a PCR amplification fragment which indicated the following cDNA insert sizes (replicas of the same original plaque are also listed): λBrhTX- 1(d) 1.1 - about 1200bp; λBrhTX- 1(d) 1.2 - aboutl200bp λBrhTX- l(d)2.1 - aboutl200bp λBrhTX- l(d)3.1 - about 1800bp; λBrhTX- l(d)3.2 - about 1800bp; λBrhTX-l(d)3.3 - about 1800bp; λBrhTX- l(d)3.4 - about 1800bp λBrhTX-l(d)4.1 - about 1200bp; λBrhTX- l(d)4.2 - about 1200bp; λBrhTX- l(d)4.3 - about 1200bp λBrhTX- l(d)5.1 - about 700bp (iv. Subcloning jtnd Sequencing of Clones As for subunit BrhTX- 1(a), phage DNA preparations were carried out using the method of Grossberger D ( 1987). The cDNA inserts were released from λBrhTX- 1 (d) 1.2, λBrhTX-l(d)3.1, λBrhTX- l(d)3.3, λBrhTX- l(d)3.4 and λBrhTX-1 (d)4.3 by Eco RI digestion. The other inserts were not released which probably indicates that the Eco RI sites had not been recreated during the original library construction. The released inserts were cloned into the Eco RI site of pUC19 and then transformed into E. coli DH5α cells as described for subunit BrhTX- 1 (a). The insert of clone pBrhTX- 1(d) 1.2 was sequenced as described for subunit BrhTX- 1(a) using fourteen synthetic oligo primers including primers PUC4 and PUC1 (given above and in Sequence ID Nos. 10 and 11). The other twelve primers were designed using the sequence data generated by the initial PUC4 and PUC1 sequencing runs, and are shown below and in Sequence ID Nos. 24 to 35.

Translation of the nucleotide sequence gave an ORF of 275 amino acids. Amino acids 23-35 correspond to the N-terminal sequence of subunit BrhTX- 1(d). Amino acids 1-22 comprise a candidate signal sequence. The estimated molecular weight of the mature protein encoded by the cDNA is 28.2 kDa. The deduced amino acid sequences are given in Sequence ID No 37. The nucleotide sequence and amino acid sequence is also shown in Figure 10. (v. Analysis of Clones Peptide Digestion/Sequencing - The protocol is as described above for subunit BrhTX- 1(a). The alignment of the sequences obtained against the deduced amino acid translations is shown below: Peptide Sequence INI(Q/R)VA Q_TvTYYLDS(I/H)K cDNA Sequence GNIK VA QIVTYYLDW I K These mismatches can be ascribed to sequencing artefacts. Genomic Southern Blot - Genomic DNA was prepared as previously described in Example 4. Aliquots of male and female DNA were digested using Bel I, Nde I, Bgl and Pst I and the digested DNA separated by electrophoresis in 0.7% agarose gels in TAE buffer. DNA was then blotted onto nitrocellulose membranes (HybondC*; Amersham UK) in a 2-20 x SSC gradient and bonded to the membrane by baking at 80°C for 4 hours. 32 P-labelled probes were synthesised by PCR using the primers BH(d)F4 and BH(d)R7 and pBrhTX- 1(d) 1.2 plasmid DNA as target DNA under the following conditions: 5 minutes at 95°C; 30 seconds at 95°C; 1.5 minutes at 43°C; 1 minute at 82°C (35 cycles); then 5 minutes at 72°C. Results for male and female DNA were identical. The Bel I digest produced two hybridising fragments, one of 10.0 kbp and one of 9.1 kbp. This result was consistent with the presence of an Nde I site in the probe hybridisation region of the cDNA sequence. The Bgl II and Pst I digests produced single hybridising fragments of 18.5 kbp and 22.1 kbp respectively and are consistent with the absence of either of these sites in the probe hybridisng region of the cDNA. Example 6 - Cloning of subunit (b. of BrhTX- 1 (i) Generation of Probes From the N-terminal sequence given in Sequence ID No. 2, two multi-species primers were designed. These probes are shown below and in Sequence ID Nos. 38 and 39. BH(b)A 5'-AC(TCA) TTG TT(TC) AC(TCA) GA(TC) CG(TC) AA-3' BH(b)B 5'-GG (ATG)CC (AG)AA (AGT)GT (TC)TT (AG)TC-3' These primers were used in a PCR experiment to generate a PCR product from cDNA synthesised from female mRNA as previously described. The PCR reaction conditions for a 0.2 μl Taq DNA Polymerase/50 μl reaction were as follows: 5 minutes at 95°C; then 30 seconds at 95°C; 1.5 minutes at 50°C; 1 minute at 72°C (5 cycles); then 30 seconds at 95°C; 1.5 minutes at 55°C; 1 minute at 72°C (30 cycles); then 5 minutes at 72°C. This PCR product is approximately 54 bp, as estimated by PAGE in 15% gels in TBE buffer. Amplification products were visualised in the gels by staining with ethidium bromide. The fragment was then cloned into the EcoRV site of the commercially available plasmid pBluescript SK- that had been tailed with a thymine residue (T-tailing) using Taq DNA Polymerase. The following conditions were used for T-tailing: 50 mM KCl, 10 mM Tris-HCl [pH 8.3], 1.5 mM MgCl 2 , 2 mM dTTP at 70°C for 2 hours. The cloned PCR product was sequenced using the following dye primers which are available from Applied Biosystems Inc: Universal M13-20 dye-primer 5 * -CAG GAA ACA GCT ATG ACC-3' M13 reverse dye-primer 5'-TGT AAA ACG ACG GCC AGT-3' Sequencing was carried out using an ABI 370 A DNA analysis system (Applied Biosystems).

Screening of library and Isolation of Clones Library plating was carried out as described above, except that plaque lifts were done in duplicate onto Nitropure nitrocellulose membranes, 137 mm 0.45 micron, (Microb Separations, Westboro, MA, USA). In the primary screen 3.6xl0 5 plaques per filter (4 filters in total) were screened, in secondary and tertiary screens 100-250 plaques per filter were screened. 32 P-labelled probes were made by PCR. PCR was carried out in the presence of 32 P- dATP using the oligonucleotides BH(b)A and BH(b)B shown in Sequence ID Nos. 38 and 39, and the cloned PCR product carrying the sequence shown in Sequence ID No. 40 as the target. The following PCR conditions were used: 95°C for 5 minutes prior to the addition of Taq polymerase; then 95°C for 30 seconds, 45°C for 1.5 minutes and 72°C for 1 minute (5 cycles); then 95°C for 30 seconds, 50°C for 1.30 minutes and 72°C for 1 minute (30 cycles); then 72°C for 5 minutes (1 cycle). Filters were probed with the 32 P-labelled probe described above under the same pre- hybridising and hybridising conditions as described for the Genomic Southern Blot of subunit BrhTX- 1(a). Ten plaques that hybridised to this probe were initially identified. Three of these were purified through second and third round screens to homogeneity. Plaque purified phage were picked into 1ml of SM buffer plus 10 μl of chloroform. fiii. Characterisation of Clones The plaque-purified phage were screened for the presence and size of a cDNA insert by PCR analysis using the oligonucleotides λgt 11 forward and λgt 11 reverse. Lambda DNA for PCR was prepared from purified stocks by boiling 10 μl of the stock for 5 minutes, two μl of this DNA was then used in PCR experiments. The amplified fragments were sized by electrophoresis through 0.8% agarose gels in TAE buffer and sized against markers of known size. Of the three purified phage, an insert of approximately 500 bp was found in one phage, which phage was designated λBrhTX- 1 (b)l. No inserts could be detected in the other two plaque-purified phages. (iv. Subcloning and Sequencing of Clones Phage DNA was purified by isopyncnic centrifugation in CsCl as described in Sambrook et al (1989). The cDNA insert from λBrhTX- 1 (b) 1 was removed by digestion with Not I and ligated into pBluescript SK- that had been digested with Not I and phosphatase treated. The insert of the clone was sequenced using the ABI dye-primer sequencing kit (as described above). The sequence of the plasmid clone, pBrhTX-l(b)l, insert is given in Sequence ID No. 41 and Figure 11. The amino acids 27-44 match those of the N-terminal sequence shown in Sequence ID No. 2, but the very short apparent size of the ORF encoded by the sequence in Sequence ID No. 41 suggested that the clone was severely truncated. We therefore designed two primers to the ORF at the 5' end of the clone, namely BH(b)C and BH(b)D as shown in Sequence ID Nos. 42 and 43 respectively. Using these primers and pBrhTX- 1(b) 1.1 as a target we generated a 32 P-labelled probe by PCR under the following conditions: 5 minutes at 95°C; 30 seconds at 95°C; 1.5 minutes at 45°C; 1 minute at 72°C (5 cycles); then 30 seconds at 95°C; 1.5 minutes at 50°C; 1 minute at 72°C (5 cycles); then 5 minutes at 72°C. The library was then re-screened using the conditions described above. Six strongly hybridising plaques were purified through to homogeneity in three rounds of plaque purification. cDNA inserts were removed from the phage by digestion with Not I and ligated into pBluescript SK- that had been digested with Not I and phosphatase treated. The sizes of the inserts were estimated by digestion with Not I and separation of restriction fragments through 0.8% agarose gels in TAE buffer. The following cDΝA insert sizes were estimated: λBrhTX-l(b)2 - about 500 bp; and λBrhTX-1 (b)3, λBrhTX-l(b)4, λBrhTX-l(b)5 and λBrhTX- 1 (b)6 all at about 1200 bp. The plasmid designated pBrhTX-l(b)6 was sequenced using the ABI 370 A DΝA analysis system and previously described dye primers. The sequencing was completed using the ABI dye-terminator system in conjunction with the BH(b)C, BH(b)D (Sequence ID Νos. 42 and 43) primers and two additional primers as shown below and in Sequence ID Nos. 44 and 45: BH(b)E GTTGTCAATACACCCTG BH(b)F AGAACGAGATGTTATTGTAT The nucleotide sequence obtained is shown in Sequence ID No. 46. Translation of the nucleotide sequence is shown in Sequence ID No.47, and gives a protein of either 182 or 165 amino acids depending upon the initiation codon used. The alternative proteins have hydrophobic leader sequences of either 21 or 4 amino acids respectively, giving a mature peptide of 161 amino acids. The nucleotide sequence of subunit BrhTX- 1(b) and the corresponding amino acid sequence is also shown in Figure 12, in which the putative ORF is shown in bold text. In particular the protein translation of the cDNA is given in Figure 13 in which the mature peptide is shown underlined. (v) Analysis of Clones Peptide Digestion Sequencing - The alignment of the sequences obtained against the deduced amino acid translations is shown below: Peptide Sequence MIKPGETYGDVTNK EWVHDNAGTLLPR cDNA Sequence MIKPGETYGDVTNK EWVHDNA LLPR Peptide Sequence PHTVYDKHESLQ DVHDNAGTLLPR cDNA Sequence PHTVYDKHESLY WVHDNA LLPQ It is not unusual for the terminal amino acids to be subject to mis-sequencing; however, one of the peptide sequences sequenced on two separate occasions contains a characteristic GT amino acid pair. These GT pair is missing in the ORF predicted for the sequenced clone. We therefore deduced that the clone pBrhTX-l(b)6 contained a sequencing artefact or that the cDNA from which it was generated contained an error, i.e. a six bp deletion generated during synthesis/cloning. We therefore recloned the region containing the apparent "GT" pair/deletion by PCR. Primers BH(b)E and BH(b)F were used in the PCR experiments with cDNA as the target, to generate an amplification product. cDNA was synthesised from female B. hebetor mRNA as previously described for the construction of the cDNA library (Example 3). The amplification products were then cloned into the EcoRV site of pBluescript that had been T-tailed as previously described. These clones were then sequenced and all were found to contain the same sequence as pBrhTX-l(b)6 flanking the apparent GT anomaly, but had an additional six bp corresponding to the codons for G and T, i.e. GGAACT. From these data it would appear that the GT anomaly arose during the cDNA synthesis cloning of the original λ clone. The consensus sequence for the pBrhTX-l(b) cDNA and the putative ORF are shown in Figure 14 and Sequence ID Nos. 48 and 49. Such sequences are also included within scope of the present invention. Genomic Southern Blot - Southern blots of male and female B. -hebetor genomic DNA digested with Pst I, EcoRV, Ace I and Xho I were generated as previously described. A 32 P- labelled probe was generated by PCR from the 5' region of the pBrhTX-l(b)6 clone using the primers BH(b)C and BH(b)D under the following conditions: 5 minutes at 95°C; 30 seconds at 95°C; 1.5 minutes at 45°C; 1 minute at 72°C (5 cycles); then 30 seconds at 95°C; 1.5 minutes at 50°C; 1 minute at 72°C (5 cycles); then 5 minutes at 72°C. Hybridisations were carried out with the probe as previously described. Results were identical for male and female DNA. In the Pst I digest two hybridising bands were observed of 13.0 kpb and 4.1 kbp. This result is consistent with the presence of a Pst I site in the probe hybridisation region of the cDNA sequence. The EcoRV, Ace I and Xho I digests produced single hybridising bands of 3.3 kbp, 13.0 kbp and 7.0 kbp respectively. In a second experiment, 32 P-labelled probes were made from the 3' region of the pBrhTX-l(b)5 clone using the primers BH(b)E and BH(b)F under the following conditions: 5 minutes at 95°C; 30 seconds at 95*C; 1.5 minutes at 45°C; 1 minute at 72°C (5 cycles); then 30 seconds at 95°C; 1.5 minutes at 50°C; 1 minute at 72°C (5 cycles); then 5 minutes at 72°C. These probes hybridised to Southern blots prepared as previously described using male and female genomic DNA that had been digested with Bel I, Nde I, Bgl U and Pst I. Results were identical for male and female DNA with the Bel I and Bgl ϋ digests single hybridising bands of 1.7 kbp and 9.1 kbp were generated. Although these results do not fully agree with the presence of both these sites within the probe hybridising region, i.e. one would normally expect to see two hybridising bands, both sites are relatively close to the ends of the probe region and the fragment containing the smaller portion of the hybridising region could well evade detection with the large probes that were used in this experiment. In the Nde I and Pst I digests, single hybridising bands of 2.4 and 22.2 kbp were detected. Example 7 - Cloning of subunit (c . of BrhTX- 1 The N-terminal sequence shown in Sequence ID No. 3 was insufficient to attempt any PCR approaches to the isolation of the gene encoding it. Peptide fragments were therefore obtained using the peptide digestion method outlined above. These peptide sequences with their presumptive coding sequence are shown in Figure 15 (where "?" indicates uncertainty over the first amino acid, and amino acids shown in brackets are where two possible options exist), and Sequence ID Nos. 50 and 51. From these sequences the following multi-species primers, BH(c)A and BH(c)B, were synthesised as shown below and in Sequence ID Nos. 52 and 53: BH(c)A 5'-TG (ATG)CC (AGT)AC (AG)TC (AGT.GC-3' BH(c)B 5'-GT(TCAG) CA(TC) AA(TQ CC(ACT) GG(TAC) AA-3' PCR against B. hebetor cDN A as described above for subunit BrhTX- 1(b) was carried out using these primers under the following conditions: 5 minutes at 95°C (1 cycle) then 30 seconds at 95°C; 1 minute at 45°C; 1 minute at 72°C (5 cycles) then 30 seconds at 95°C; 1 minute at 50°C; 1 minute at 72°C (30 cycles) then 5 minutes at 72°C (1 cycle). A PCR product of approximately 300 bp was generated which was cloned into T-tailed pBluescript SK-, and sequenced as described above. The sequence of this PCR product is given in Sequence ID No. 54 and Figure 16. fii. Screening of library and Isolation of Clones Library plating was carried out as for subunit BιhTX-l(b). 32 P-labelled probes were synthesised by PCR using the primers BH(c)A and BH(c)B and the cloned PCR product carrying the sequence shown in Sequence ID No. 54 as target DNA. The PCR was carried out under the following conditions: 5 minutes at 95°C (1 cycle) then 30 seconds at 95°C; 1.5 minute at 45°C; 1 minute at 72°C (5 cycles) then 30 seconds at 95°C; 1.5 minute at 50°C; 1 minute at 72°C (30 cycles) then 5 minutes at 72°C (1 cycle). Five plaques were purified through to homogeneity as previously described by three rounds of plaque purification. (iii) Characterisation of Clones The size of the cDNA inserts were estimated by PCR using the λGT 11 forward and reverse primers as previously described. The following insert sizes were estimated: λBrhTX- 1 (c) 1 - about 690 bp λBrhTX- l(c)2 - about 1,8000 bp λBrhTX- l(c)3 - about 690 bp λBrhTX- l(c)4 - about 700 bp λBrhTX- l(c)6 - about 690 bp. (iv. Subcloning and Sequencing of Clones Phage DNA was purified by isopyncnic centrifugation in CsCl as described by Sambrook et al (1989). The cDNA insert from λBrhTX- l(c)5 was liberated by digestion with Not I and was cloned into the Not I site of pBluescript SK- as previously described. This plasmid clone is designated pBrhTX-l(c)5. The insert in pBrhTX-l(c)5 was sequenced using the ABI dye-primers as described previously and the ABI dye-terminator sequencing system in conjunction with the following primers: BH(c)Fl CGCTCTGGCAAACACTCTAT BH(c)Rl GGTGGAGCAAGCAAACTAAA This primers are also shown in Sequence ID Nos. 55 and 56. The nucleotide sequence obtained is shown in Sequence ID No. 57. The putative translation of this cDNA sequence gave an ORF of 145 amino acids and a predicted molecular weight of 18.8 kDa, which is shown in Sequence ID No. 58. The nucleotide sequence and putative amino acid sequence of the cDNA are also shown in Figure 18. (v. Analysis of Clones Peptide Digestion/Sequencing - The alignment of the N-terminal protein sequence obtained directly from the BrhTX- 1(c) subunit with the deduced amino acid from the cloned cDNA is shown below: Peptide Sequence MDDGE- - E - -MNP- -D cDNA Sequence MDDGETCERCLNPLEL the mismatches in the latter half of the direct protein sequence can be ascribed to sequencing artefacts arising from relatively low amounts of protein available, which also accounts for the missing amino acids (which gave indecipherable peaks in the sequencing). The alignment of the tryptic peptide sequence with the deduced amino acid sequence from the cDNA are shown below: Peptide Sequence (G/H)VHNPGNFR cDNA Sequence H VHNPGNFR The disagreement/ambiguity at the end of the sequence shown above can be ascribed to artefacts in the protein sequencing. Genomic Southern Blot - Southern blots of male and female B. hebetor genomic DNA digested with Bel I, Nde I and Bgl II were generated as previously described. A 32 P-labelled probe was generated by PCR from the 5' region of the pBrhTXl(c)5 clone using the primers BH(c)Fl and BH(c)Rl under the following conditions: 5 minutes at 95°C; 30 seconds at 95°C, 1.5 minutes at 45 °C, 1 minutes at 72°C (5 cycles); then 30 seconds at 95°C, 1.5 minutes at 50°C, 1 minutes at 72°C (5 cycles); 5 minutes at 72°C. Hybridisations were carried out with probe as previously described. Results were identical for male and female DNA. In the Bel I digest two hybridising bands were observed of 3.3 kbp and 1.8 kbp. This result is consistent with the presence of a Bel I site in the probe hybridisation region of the cDNA sequence. The Nde I and Bgl U digests produced single hybridising bands of 3.1 kbp, 17.6 kbp respectively.
