Description: CYCLIC DI-GUANYLATE METABOLIC ENZYMES Field of the Invention The invention relates to the field of recombinant DNA techniques for the production of proteins and the manipulation of metabolic pathways. More specifically, this invention relates to the cloning of diguanylate cyclase operons, the expression and regulation of the operons, and methods of using the operons for modifying the production of cellulose in microorganisms. Background of the Invention Cellulose is relied upon as the raw material for a number of useful products including paper products and wound dressings. Cellulose may be obtained from plants and various microorganisms in culture, for example from the cellulose producing bacteria of the genus Acetobacter. Acetobacter is characteristically a Gram-negative, rod-shaped bacterium 0.6-0.8 μm by 1.0-4 μm. It is strictly aerobic; metabolism is respiratory, never fermentative. It is further distinguished by the ability to produce multiple poly / 3(l-4)-glucan chains, chemically identical to cellulose. Multiple cellulose chains or microfibrils are synthesized at the bacterial surface at sites on the cell wall. The production of cellulose by Acetobacter has been the subject of intense study since at least the 1930's. In particular, Acetobacter xylinum has been widely studied to attempt to elucidate the mechanism of cellulose synthesis in intact cells [Schramm and Hestrin, (1954) J. Gen. Microbiol. 11:123- 129]. The enzymatic pathway for cellulose synthesis in Acetobacter xylinum has been investigated and essen¬ tially four enzymatic steps have been characterized in cell-free extracts of A. xylinum which appear to comprise the complete pathway from glucose to cellulose. These are the phosphorylation of glucose by glucokinase [Benziman, et al. , (1972) J. Bactβriol.. 111:325-330], the isomerization of glucose-6-phosphate to glucose-1- phosphate by phosphoglucomutase [Gromet, et al., (1957) Biochem. J.. 67:579-689; Frei-Roit an, Factors affecting the activity of phosphoglucomutase and UDP-glucose pyrophosphorylase of Acetobacter xylinum. M.Sc. thesis, The Hebrew University of Jerusalem, Jerusalem, Israel (1974)]; the synthesis of uridine 5'-diphosphoglucose (UDP-glc) by UDPG-pyrophosphorylase, [Frei-Roitman, supra: Swissa, Biosynthesis of cellulose in Acetobacter xylinum. Ph.D. thesis, The Hebrew University of Jerusalem,. Jerusalem, Israel (1978)], and the cellulose synthase reaction. The novel nucleotide activator c-di-GMP, i.e., cyclic diguanosine monophosphate is essential for the high activity of cellulose synthase. Ross ≤£ al.. Nature 325:279-281 (1987); Ross e_£ al.. Carbohyds Res. 149:101- 117 (1986). Studies of cell-free preparations from A. xylinum have given rise to a model in which c-di-GMP functions as a reversible, allosteric activator of the membrane-bound cellulose synthase, the enzyme that performs the "committed" step in cellulose biosynthesis. The concentration of c-di-GMP, the net result of the ongoing synthesis and degradation of c-di-GMP is controlled by the opposing action of the associated enzymes which together account for these two pathways. Diguanylate cyclase (abbreviated as DGC) catalyzes the synthesis of c-di-GMP from two molecules of GTP, via the linear dinucleotide triphosphate pppGpG, in two distinct, pyrophosphate-releasing steps. Within the cell, inorganic pyrophosphate is rapidly cleaved to yield orthophosphate, Benziman and Palgi J. Bacteriol. 104:211-218 (1970). The pathway of c-di-GMP degradation is initiated by a c-di-GMP - specific, Ca ++ -sensitive phosphodiesterase A, PDE-A, which cleaves a single phosphodiester bond in the cyclic structure, yielding the linear dimer pGpG and simultaneously inactivating the molecule. The mononucleotide residues of the inactive dimer structure are then recovered as free 5'- GMP units through the action of phosphodiesterase B, PDE-B. The Ca ++ -inhibition of PDE-A may represent an additional locus of regulatory control; according to this model, fluctuations in Ca ++ levels may modulate the rate of cellulose synthesis as they influence the level of activator in the system. As with its cyclic mononucleotide-for ing counterparts, adenylate-and guanylate cyclase, the diguanylate cyclase of A. xylinum appears to occur in both a cytoplasmic and a membrane-associated form. The pathway of c-di-GMP synthesis attributed to diguanylate cyclase proceeds from GTP via the diguanosine tetraphosphate intermediate pppGpG (115; P. Ross, Ph.D. Thesis, The Hebrew University of Jerusalem, 1990). Each of the two 3'-5' phosphodiester bond-forming, pyrophosphate-releasing steps in the pathway appears to be catalyzed by a single enzyme on the basis that a separate pppGpG - forming activity has not been isolated in the course of purification. While native diguanylate cyclase appears to be a multi-subunit enzyme, the precise nature of its subunit composition has not been completely ascertained. The enzyme has been purified by =2000 fold by affinity chromatography based on an immobilized form of the GTP substrate, Ross, ei aj.. , FEBS Lett.. 186:191-196 (1985); Ross, ≤i il, Carbohydr. Res.. 149:101-117. Polyclonal antibodies raised against two different peptides (61 and 57 kDa, also referred to as bands III and IV, respectively) , both highly-enriched in the course of the purification, have been shown to bind to the native enzyme but not to be cross-reactive with respect to the original antigens (P. Ross, Ph.D. Thesis, The Hebrew University of Jerusalem, 1990) . Thus the native, soluble form of diguanylate cyclase, which bears a molecular weight of 190 kDa, appears to be a hetero- oligomeric protein. Two phosphodiesterases, PDE-A and PDE-B, are associated with the C-di-GMP degradation pathway. PDE- A is the more important of the two enzymes in determining C-di-GMP levels because it inactivates c- di-GMP by cleaving the molecule to form pGpG. This form of negative control is irreversible in the sense that, at least within the in vitro system, the pGpG degradation intermediate is not subject to re- phosphorylation (in the co-presence of ATP) but rather is rapidly degraded to produce two molecules of 5'-GMP. This latter reaction, catalyzed by the activity of PDE- B, evidently serves a salvage role, regenerating monophosphate units from one round of c-di-GMP formation and breakdown for de novo GTP synthesis.. The Mg ++ -dependent PDE-A and PDE-B reactions have been determined to be distinct enzymes mainly by the criteria of sensitivity to divalent cations, differential degree of intracellular distribution, and immunoche ical analysis, in addition to substrate specificity (R. Mayer, MSc Thesis, The Hebrew University of Jerusalem) . The ratio of PDE-A to PDE-B activity in membrane preparations is approximately 10:1, while in soluble extracts this ratio is reversed. Anti-sera which effectively inhibits PDE-A activity has no inhibitory or binding effect on the PDE-B enzyme. Furthermore, in contrast to the PDE-B reaction, the Mg ++ - requiring (K a «4 M) PDE-A activity is inhibited at low (K 1/2 *=50/iM) concentrations of Ca ++ -ions. Kinetically, the PDE-A reaction obeys a first order rate pattern (K H «0.25/iM) typical to an enzyme bearing a single substrate-binding site. The c-di-GMP -specific, Ca ++ -sensitive PDE-A occupies a crucial regulatory role and has been studied in further detail, with particular regard to regulatory properties and substrate specificity. A subunit molecular weight of 85 kDa has been assigned to the membrane-associated PDE-A, which in soluble form displays a native weight of =190 kDa. The inhibitory effect of Ca ++ on the rate of hydrolysis of c-di-GMP appears to result directly from a reduction in the catalytic constant (V,.,^) of PDE-A activity, rather than from a Ka effect (Ross e_£ al. , J. Biol Chem 265:18933- 18973 (1990)). The mechanism of inhibition does not appear to be allosteric in nature, as via a specific Ca ++ - binding site which paralyzes the enzyme when occupied, but rather may involve specific interaction with the cyclic dinucleotide substrate. PDE-A activity is sensitive as well to the presence of polyethylene glycol; inhibition of c-di-GMP degradation offers an adequate explanation for the previously reported potentiating effect of this hydrophilic, protein aggregating polymer on the cellulose synthase reaction under cell-free assay conditions. There is biochemical evidence to suggest that organisms other than Acetobacter posses peptides that are homologous to edg peptides and cellulose synthase peptides. This evidence is based on detection of c-di- GMP synthetic activity, GDC activity, and cellulose synthase activity in cellulose synthesizing bacteria like Aσrobacterium tumefaciens and cross reacting activity of antiserum for cellulose synthase hs_s.B with variety of plant cells. Interestingly, these peptides which cross react with antiserum to the b_£≤B peptide also bind. UDPG and c-di-GMP in affinity labeling studies. For a review of those experiments see P. Ross, ≤t al. -■ (1991) icrpfripl, Rev,, 55(1), 35-58. Given the importance of c-di-GMP in regulation of cellulose synthase activity, the ability to produce recombinant c-di-GMP metabolic enzymes provides useful mechanisms for regulating cellulose synthesis, ultimately providing enhanced cellulose production from cells grown in culture. Summary of the Invention The present invention provides for operons encoding enzymes for the biosynthesis and degradation of c-di- GMP (cyclic-di-guanosine monophosphate) , a positive allosteric regulator of cellulose synthase. Three operon sequences isolated from Acetobacter are specifically disclosed: cdσl . cdg2. and cdg3. These operons contain genes encoding diguanylate cyclase (dgc) and c-di-GMP phosphodiesterase A fpdeA) . These operons also contain nucleotide sequences encoding other proteins of interest, including CDG1A and CDG1D. The nucleotide sequences of edg operons, including cdgl. cdg2, and cdσ3 or portions thereof, find a variety of uses including the preparation of purified compositions of any polypeptide encoded by the operons, vectors containing nucleotide sequences encoding edg operon proteins, and hybridization probes for the detection of genes encoding edg operon genes. Another aspect of the subject invention is to provide for genetically manipulated strains of cellulose producing bacteria, including Acetobacter species, wherein the expression levels of edg operon encoded proteins is either increased or decreased, thereby modifying the intracellular level of c-di-GMP, and hence cellulose synthase activity and cellulose synthesis, in the cell. Of particular interest is the production of genetically manipulated strains producing elevated levels of CDG activity and/or decreased levels of PDE- A activity.

Detailed Description of the Invention In order that the invention herein described may be more fully understood, the following detailed description is set forth. A. Definitions As used herein, the term "Acetobacter" refers to a particular genus of bacteria described in detail in Berσey's Manual of Determinative Bacteriology. Buchanan and Gibbons eds., Williams and Wilkins Publishers. The specific strains of Acetobacter from the nucleotide sequences of the subject invention where isolated are Acetobacter 1306-11 (ATCC deposit number 53263) and Acetobacter 1306-21 (ATCC deposit number 53524), the isolation of which are described in detail in PCT Application PCT/US90/01811. As used herein, the term "diguanylate cyclase" refers to one or more polypeptides having diguanylate cyclase activity. Diguanylate cyclase activity refers to the property of enzymatically converting two molecules of GTP (guanosine triphosphate) to bis- (3' 5') - cyclic diguanylic acid. At least 3 diguanylate cyclase enzymes have been identified in Acetobacter. DGCl, as encoded by the dgcl gene in the cdgl operon and the DGC2, as encoded by the dgc2 gene in the cdg2 operon and DGC3 encoded by dgc3 in cdg3 operon. The term "DGC" refers to any enzyme with diguanylate cyclase activity, including DGCl, DGC2 and DGC3. The term "diguanylate phosphodiesterase" refers to one or more polypeptides having "diguanylate phosphodiesterase activity." "Diguanylate phosphodiesterase activity" refers to the property of enzymatically cleaving a single phosphodiester bond in c-di-GMP to yield the linear dimer pGpG, i.e., the activity of the diguanylate phosphodiesterase A enzyme, as opposed to the enzyme diguantate phosphodiesterase B. At least three diguanylate phosphodiesterases have been identified from Acetobacter. PDEAl, as encoded by the pdeAl gene in the cdgl operon, PDEA2 as encoded by the pdeA2 gene in the ' cdg2 operon and PDEA3, as encoded by the pdeA3 gene in the cdg3 operon. The term "PDE- A" refers to any enzyme with diguanylate phosphodiesterase activity, including PDEAl and PDEA2. The terms "cyclic diguanylic acid operon", "edg operon", "edg" . and "cdσ operon" mean the same thing, and refer to operons containing genes encoding enzymes with either diguanylate cyclase activity, diguanylate phosphodiesterase activity, or both. A edg operon may also encode one or more regulatory proteins having the property of modulating the expression of one or more edg operon proteins. These terms are not limited to any particular Acetobacter strain or species. The operon may also include ranscriptional- and translational regulatory elements such as promoter sequences, transcriptional terminator sequences, attenuator sequences, operator sequences, and the like. "cdgl" . "cdg2" and "cdg3" refer to the Acetobacter edg operons represented (at least in part) by Figures 1 2, and 3 respectively. The term "edg operon gene" is defined as a nucleic acid sequence encoding a polypeptide product and encoded by a edg operon. The term "edg operon protein (or polypeptide)" refers to any polypeptide encoded by a edg operon gene. In addition.to referring to polypeptides encoded by edg operon genes, the term "edg operon protein", which includes PDE-A1, PDE-A2, PDE-A3, DGCl, DGC2, DGC3, CDG1A, and CDG1D, refers to various derivatives of the polypeptides encoded by naturally occurring edg operon sequences. "Operably linked" refers to a juxtaposition such that the normal function of the components can be performed. Thus, a coding sequence "operably linked" to control sequences refers to a configuration wherein the coding sequences can be expressed under the control of these sequences. Such control may be direct, that is, a single gene associated with a single promoter, or indirect, as in the case where a polycistronic transcript is expressed from a single promoter. "Control sequence" refers to a DNA sequence or sequences necessary for the expression or regulation (transcriptional or translational) of an operably linked coding sequence in a particular host organism. The control sequences which are suitable for procaryotes, for example, include a promoter, optionally an operator sequence, a ribosome binding site, a transcription terminator, and possibly other as yet poorly understood sequences. Eucaryotic cells are known to utilize promoters, polyadenylation signals, enhancers, silencers, and the like. By "elevated levels" of expression of a molecule of interest, it is intended that a cell expressing "elevated levels" of that molecule contains more molecules for each cell under a given set of growth conditions than a similar cell not producing "elevated levels" of the molecule of interest. By "reduced levels" of expression of a molecule of interest, it is intended that a cell expressing "reduced levels" of that molecule contains less molecules for each cell under a given set of growth conditions than a similar cell not producing "reduced levels" of the molecule of interest. "Cells" or "recombinant host cells" or "host cells" are often used interchangeably, and all such designation include progeny. Thus "transformants" or "transformed cells" includes the primary subject cell and cultures derived therefrom without regard for the number of transfers. It is also understood that all progeny may not be precisely identical in DNA content, due to deliberate or inadvertent mutations. Mutant progeny which have the same functionality as screened for in the originally transformed cell are included. Where distinct designations are intended, it will be clear from the context. When a specific polypeptide sequence is referred to, the amino acid sequence of the protein referred to includes amino acid sequences derived from the naturally occurring sequence. A polypeptide "derived from" a -designated sequence refers to a polypeptide having an amino acid sequence identical to, or in substantial correspondence with a polypeptide encoded in the sequence, or a portion thereof wherein the portion consists of at least 5-10 amino acids, and more preferably at least 10-15 amino acids, which is immunologically identifiable with a polypeptide encoded in the sequence, or exhibits similar biological activity as that of the reference protein in the in vitro or in vivo assays described herein. As used herein with reference to an amino acid sequence "substantial correspondence" refers to a sequence usually differing by fewer than 10 amino acids, more usually differing by fewer than 5 amino acids. The recombinant protein, displays substantially the same biological properties as the naturally occurring protein. The biological properties may include immunological properties, where antibodies raised to the authentic protein cross-react with the recombinant protein. When a specific nucleotide sequence is referred to, the nucleotide sequence referred to includes nucleotide sequences derived from the naturally occurring sequence. A polynucleotide "derived from" a designated sequence, for example, the DNA from the pdeAl . refers to a polynucleotide sequence which is comprised of a sequence of at least 6-20 nucleotides, more preferably at least 15 to 20 nucleotides corresponding, i.e., identical to or complementary to, a region of the designated nucleotide sequence. The correspondence to the nucleic acid sequence will be approximately 70% or greater, will preferably be at least 80%, and even more preferably will be at least 90%. The correspondence or non-correspondence of the derived sequence to other sequences can be determined by hybridization under the appropriate stringency conditions, using standard DNA hybridization technologies in liquid phases or on solid supports. Hybridization techniques for determining the complementarity of nucleic acid sequences are known in the art (see, for example, Sambrook, et al. (1989) Molecular Cloningr A Laboratory Manual, Second Edition, Cold Spring Harbor Press, Cold Spring Harbor, NY). In addition, mismatches of duplex polynucleotides formed by hybridization can be determined by known techniques, including digestion with a nuclease such as SI, that specifically digests single-stranded sequences in duplex polynucleotides. The derived polynucleotide is not necessarily physically derived from the nucleotide sequence shown, but may be generated in any manner, including, for example, chemical synthesis, DNA replication or reverse transcription, which methods are based on the information provided by the sequence of bases in the region(s) from which the polynucleotide is derived. The term "recombinant polypeptide" as used herein to characterize a edg operon polypeptide intends a polypeptide encoded by geno ic, cDNA, semisynthetic, or synthetic nucleic acid sequences which, by virtue of their origin or manipulation: (1) are not associated with all or a portion of the polynucleotide with which they are associated in nature or in the form of a library; and/or (2) are linked to a polynucleotide sequence other than that to which it is linked in nature. "Expression system" refers to DNA sequences containing a desired coding sequence and control sequences in operable linkage, so that host cells transformed with these sequences are capable of producing the encoded proteins. In order to effect transformation, the expression system may be included on a vector; however, the relevant DNA may also be integrated into the host chromosome. ~" The term "heterologous" when used in reference to polynucleotide sequences, refers to polynucleotide sequences not naturally present in a cell or present at a particular genome location. Thus the term heterologous includes, for example, the promoter of gene A operably joined to structural gene B, when A and B genes are from the same organism, as well as the case in which a polynucleotide sequence of one species is transferred to a cell of a different species (or strain) . As used herein, the term "vector" refers to a polynucleotide sequence suitable for transferring nucleic acid sequences into a host cell. The term may include plasmids, mini-chromosomes, phage, naked DNA and the like. The term "genetic manipulation" intends the purposeful alteration of polynucleotide sequences either by in vitro techniques, in vivo techniques, or a combination of both in vitro and in vivo techniques. "Genetic manipulation" includes the introduction of heterologous polynucleotide sequences into cells either into the chromosome or as an extrachromosomally replicating elements, the alteration of chromosomal polynucleotide sequences, the addition and/or replacement of transcriptional and/or translational regulatory signals to chromosomal or plasmid encoded genes, and the introduction of various insertion, deletion and replacement mutations in genes of interest. Methods for in vitro and in vivo genetic manipulations are widely known to those skilled in the art and can be found, for example, in Sambrook, e_£ al.. Molecular Cloning: A Laboratory Manual. 2nd Ed. , Cold Spring Harbor Press (1989), Goeddel, Method in Enzvmoloσy. Vol. 185, Academic Press (1990). Specific techniques for the genetic manipulation of Acetobacter species can be found in U.S. patent applications 07/689,008 which are herein incorporated by reference. The term "recombinant" when used to refer to cells, intends cells that have been genetically manipulated, or are the progeny of cell that have been genetically manipulated. The composition of all bacterial growth media used in this application can be found in U.S. Patent Application No. 07/689,008 filed April 22, 1991. B. Specific Embodiments This section provides the nucleotide sequences of the cdgl f cdg2 and cdg3 operons, the amino acid sequences of edg operon encoded proteins, purified preparations of edg operon proteins, and cells possessing the ability to produce either elevated or diminished levels of one or more edg operon proteins. (i) General Description The subject invention, among other things, provides the nucleotide sequence of portions of at least 3 c-di- GMP operons isolated from Acetobacter. The first of the operons, cdgl (SEQ ID No: 1), comprises at least 4 genes. In order of transcription these genes are: (1) cdglA. a gene of unknown function; (2) pdeAl. a diguanylate phosphodiesterase; (3) dgcl. a diguanylate cyclase, (4) cdglD. a gene of unknown function. The second of the three isolated operons, cdσ2 (SEQ ID No.: 2) has at least 2 genes, in order of transcription, these genes are: (1) pdeA2 , a diguanylate phosphodiesterase; and (2) dgc2 , a diguanylate cyclase. The third of the three isolated edg operons, cdσ3 has at least 2 genes; (1) B4£A3, a diguanylate phosphodiesterase, and (2) dgσ3 , a diguanylate cyclase. The cdgl operon may contain more than 4 genes, cdg2 operon may contain more than 2 genes, and the cgd3 operon may contain more than 2 genes. The presence of these other genes may be readily detected by standard recombinant DNA library screening techniques such as nucleic acid hybridization screening of genomic libraries with hybridization probes derived from the 5' or 3' terminal regions of the cdgl . cdg2. or cdg3 operon sequences. Additional edg operon sequences discovered by the library screening may then be subjected to DNA sequencing in order to detect open reading frames, and thus the amino acid sequence of these other edg operon encoded polypeptides. An important aspect of the subject invention is the discovery that Acetobacter strains may contain more than one edg operon. Without the knowledge of the existence of multiple edg operons, a successful strategy for the inactivation of edg encoded genes might not be achieved because of residual expression of non-inactivated genes. The edg operon genes are highly homologous to one another at both the amino acid and the nucleotide level, as can be seen in Figures 12-16. Homo-logy scores are calculated based on the method of Genalign multiple Sequences Alignment Program from Intellegenetics. It will be appreciated by those skilled in the art that homologous regions between proteins may be evolutionarily conserved, and it is unlikely that substantial amino acid sequence changes, can be made in the conserved regions without altering the enzymatic properties of the protein. Thus by considering regions of homology between different σdg operon polypeptides and nucleic acid sequences, guidance is provided to one seeking to modify the amino acid sequence of a cdσ operon protein without substantial loss of the biological activity of the protein. Although the function of the proteins encoded by cdglA and by cdglD have not been identified, comparison of the amino acid sequence of CDG1A and CDG1D with protein data bases reveal homology with known.proteins. CDG1A bears 29% amino acid identity and 53% similarily with the protein encoded by fixK of Rhizobiu melliloti, a nitrogen fixation operon regulatory gene. CDG1D bears 38% amino acid identity and 59% similarity over 100 amino acid residues, with the protein encoded by Eii A of IL. coli. an adenylosuccinate synthetase, which converts IMP to adenylosuccinate (later converted to ATP) . It will be appreciated by those skilled in the art that as a result of the degeneracy of the genetic code, a multitude of nucleotide sequences, some bearing minimal nucleotide sequence homology to the nucleotide sequence cdgl and cdσ2 may be produced. The invention has specifically contemplated each and every possible variation of peptide or nucleotide sequence that could be made by selecting combinations based on the possible amino acid and codon choices made in accordance with the standard triplet genetic code as applied to the sequences of figures 1-3, and all such variations are to be considered as being specifically disclosed. (ii) Construction of Strains Expressing Altered Levels of c-di-GMP Metabolic Enzymeg By providing the nucleotide sequence of edg operons cdgl and cdg2. the subject invention provides for cells genetically manipulated so as to be altered with respect to the ability to produce levels of edg operon polypeptides under specific growth conditions. The genetic manipulations of interest involve alterations of edg operon nucleotide sequences or sequences adjacent to cdσ operon sequences. These alterations include the ability to express one or more edg operon protein at elevated levels compared to the levels prior to genetic manipulation, the expression of one or more edg operon gene proteins at reduced levels, and the altered regulation of expression of one or more edg operon proteins. Genetically manipulated cells may also be produced in which expression of several edg operon encoded polypeptides is altered so as to achieve different levels of expression relative to the wild type level, e.g., the expression of one cdσ operon encoded protein may be increased and the expression of a second cdα operon encoded protein may be reduced. Cells for genetic manipulation of the edg operon may be prokaryotic or eukaryotic, prokaryotic cells being preferred. Procaryotic cells for genetic manipulation include bacterial species naturally containing edg operons and strains of species not naturally encoding edg ©perons. Particularly preferred species for genetic manipulation are cellulose producing bacterial species, especially Acetobacter species. It is also of interest to genetically manipulate cdα operons in cells not naturally producing cellulose synthase, but genetically manipulated to do so. Recombinant DNA methodology may be employed to create bacterial strains producing reduced quantities, including the complete absence, of edg operon proteins, reduced levels of PDE-A being of particular interest. The creation of these strains producing reduced levels of edg operon derived proteins may be achieved by the introduction of "inactivating genetic constructs" into bacterial strains for genetic manipulation. When introduced into cells for genetic manipulation, inactivating constructs preferably reco bine by a homologous recombination mechanism into various sites within edg operons, or adjacent polynucleotide sequences, so as to reduce the expression of one or more edg operon polypeptides. Inactivating constructs may contain a region of nucleotide sequence substantially homologous to a portion of a edg operon. By "substantially homologous" it is intended that there be sufficient homology between the two sequences to permit the cell's endogenous homologous recombination mechanisms to function. The region of the genetic construct substantially homologous to a portion of a edg operon preferably contains a disruption of the homologous region. By disruption, it is intended a mutation that if present in a chromosomal copy of a edg operon would reduce the expression of one or more edg operon proteins. These mutations include insertions, deletions, and replacements (preferably nonsense codon generating replacements) of one or more nucleotides. Preferred mutations are insertions within a coding region of the edg operon region of the inactivating vectors. More preferably, these insertion nucleotide sequences encode a genetic marker selectable in the organism of interest, thereby providing for the monitoring of the edg operon disruption process. Inactivating genetic constructs may or may not contain a vector sequence, i.e., a nucleotide sequence capable of independent replication. Inactivating genetic constructs are preferably incapable of replication in the organism to be modified. Thus introduction of an inactivating genetic construct into an organism for modification will necessarily results in recombination into the chromosome or loss in subsequent cell divisions. Inactivating constructs may contain a replicon functional in at least one organism but incapable of replication in the organism which is to be genetically modified. Inactivating constructs containing a replicon preferably contain a mobilization sequence permitting the transfer of the inactivating construct from a species in which the replicon is functional to species in which the replicon is not functional by the process of conjugation. Alternatively, inactivating constructs not containing replicons may be introduced into cells for genetic manipulation by the process of transformation. When inactivating a single gene within a cdα operon, preferred inactivating genetic constructs may contain nucleotide sequence alterations that do not disrupt the reading frame of the g operon protein gene in which the mutation is made, thereby minimizing polar effects on the transcription of other cdσ operon genes. Other means of decreasing the expression of cdα operon encoded genes include the production of anti- sense RNA complementary to a portion of the edg operon. The anti-sense RNA may be expressed from a plasmid vector or from a vector inserted into the chromosome of the cells of interest. When creating cells lacking the ability to express a edg-operon gene, inactivation of all expressed copies of the gene present in the cell is necessary, otherwise residual expression from other copies of the cdσ operon gene may occur. In Acetobacter species, particularly Acetobacter 1306-21. each cdα operon may contain a pdeA and a dσc gene. When more than one cdα operon is present in a cell, the different operons may be transcribed at different rates, thus significant decrease in cdα operon gene expression may be achieved by inactivating fewer than all of the edg operons in a cell. When inactivating more than one edg operon by means of more than one inactivating genetic constructions, it is preferable that the different inactivating genetic constructions contain different selectable markers. In addition to using inactivating genetic constructs to reduce or eliminate the expression of edg operon genes, the subject invention also provides for the reduction or elimination of edg operon gene expression by means of anti-sense RNA. Various edg operons, or portions thereof, preferably portion that are conserved between isozymes of different edg operons from the same organism, may be functionally joined to promoter sequences in reverse-orientation so as to provide for anti-sense transcripts. Anti-sense RNA is particularly useful for reducing the expression of genes transcribed from multiple operons. The promoter (and associated regulatory sequences) initiating the transcription of anti-sense RNA may be constitutive or inducible. The anti-sense RNA producing "gene" may be located on the chromosome of the organism of interest or may be located extra-chromasomally, e.g., plasmid-borne. The subject invention also provides for cells that produce elevated levels of one or more edg operon encoded proteins, elevated levels of DGC being especially of interest. Increased levels of expression may be achieved by a variety of genetic manipulations, including placing cdσ operons, or portions and thereof, on multi-copy plasmids (or other similar vectors), and operably joining high level heterologous promoter sequences to cdα sequences (either on plasmids or on the chromosome) . High level heterologous promoters may be operably linked to edg sequences for expression by n vitro manipulations and introduced into cells of interest. When introduced into cells of interest the edg sequences joined to the heterologous promoter sequences may recombine into the chromosome so as to replace a region of chromosome containing the promoter sequence naturally joined to a edg operon. In addition to operably linking high level promoters to cdα operon encoded genes, other transcriptional control sequences (promoters, operators, attenuators and the like) may be operably linked to edg operon genes so as to provide for inducible or constitutive expression of edg operon encoded gene or genes. Thus the regulation of edg operon genes may be altered so as to provide for expression during specific growth phases and under the desired media conditions. -Genetic techniques for joining transcriptional control -sequences to edg operon sequences are essentially the same as the previously discussed techniques for joining heterologous high level promoters to cdα operon sequences. The previously discussed techniques for modifying the expression of edg operon genes are not limited to genes encoding enzymes, but also include the modification of expression of edg operon encoded regulatory genes. It will be appreciated that increases in the expression of edg operon genes may be increased by increasing the expression of a transcriptional activator or decreasing the expression of a transcriptional repressor; the converse being true for decreasing the expression of edg operon genes. Other means for modulating the expression levels of edg operons include the titration of cdσ operon regulatory polypeptides having the ability to bind to specific nucleotide sequences within edg operons. Titration at these regulatory proteins may be achieved by placing edg operon nucleotide sequences that bind regulatory proteins on multicopy number plasmid capable of replicating in suitable cells. For example, the expression of a edg operon gene may be decreased if a polypeptide exists that stimulates transcription of a edg operon and the nucleotide sequence that polypeptide binds to is placed on a high-copy number plasmid. Nucleotide sequences capable of binding edg operon regulatory proteins may be readily determined by performing sequential deletion analysis of nucleotide sequences known to modify the expression of edg operon genes. The subject invention provides for conferring the ability to produce c-di-GMP a desired levels on a variety of cells b -transferring genetic constructions comprising edg operons or portions thereof, especially dgc genes, into cells of interest. These genetic constructions may be capable of expressing DGC, or both DGC and PDEA. Cells of interest for synthesizing c-di- GMP may be eukaryotic or prokaryotic, prokaryotic cells being preferred. Of particular interest is the introduction of these genetic constructions into cells possessing the ability to produce a cellulose synthase- having an activity that is capable of being modulated interaction with c-di-GMP preferably cellulose synthase from Acetobacter species, more preferably from Acetobacter 1306-21. Cells of interest may naturally produce cellulose synthase or be genetically modified to do so. Furthermore, it is of interest to in details on how to transfer the ability to produce cellulose synthase to cells not naturally producing cellulose synthase, e.g., E_ι_ coli can be found in co-pending U.S. patent application 07/689,008, filed April 22, 1991 which is herein incorporated by reference. Since c-di- GMP may increase the activity of cellulose synthase, it may be of interest to confer the ability to produce c- di-GMP on cells producing cellulose synthase. (iii) Isolation of cdo Operon Sequences The polynucleotide sequences encoding edg operons were obtained from an Acetobacter 1306-3 and Acetobacter 1306-21 genomic DNA library, as set forth in the examples. Oligonucleotide probes pools were produced based on information obtained by Edman degradation amino acid sequencing of purified Acetobacter DGC and PDEA enzymes. The oligonucleotide pools were used as primers for PCR reactions amplifying Acetobacter chromosomal DNA; the amplified region of the chromosomal DNA was used as a hybridization probe to screen the library. Alternatively, hybridization probes were produced solely from amino acid sequence information obtained from purified proteins without reliance on a PCR amplification step. Library isolates were confirmed by comparison with deduced amino acid sequences obtained from DNA sequencing the clones against the amino acid sequence obtained from amino acid sequencing the isolated proteins. The DNA sequences isolated from the library were used to construct strains of Acetobacter in which production of protein encoded by the cloned gene was abolished. Analysis of the enzymatic activity of these genetically manipulated strains revealed the presence of multiple PDEA and DGC encoding genes. SDS- PAGE analysis and western blots of " extract made from Acetobacter strains genetically manipulated so as to not produce specific cdα operon polypeptides were used to confirm the identity of the cloned genes. The nucleotide sequences of operon cdgl . (SEQ ID No: 1), cdα2 (SEQ ID No: 2), and cdc3 (SEQ ID No: 3) or portions thereof may be used as hybridization probes for the isolation of homologous genes from genetic libraries produced from the genomes of a variety of species, including those species other than those from which cdgl and cdg2 were isolated. Species of particular interest include species producing bacterial cellulose synthase, these species include species from the genera Acetobacter. Agrobacteria. Sarcinae, and Rhizobia. Techniques for the screening of genetic libraries are well known and can be found for example in Molecular Cloning: A Laboratory Manual 2nd Ed. , Sambrook, e_£ ^1. , Cold Spring Harbor Press (1989). Suitable nucleic acid hybridization probes for the detection of cdα operon gene homologous sequences comprise at least 14, preferably 25, and more preferably at least 500 nucleic acid base pairs from the sequence of cdgl. cdg2. or cdσ3. Hybridization probes may be labeled by a variety of labels including radionuclides, such as ^p or ^S, or enzymatic labels such as alkaline phosphatase coupled: to the probe via avidin/biotin coupling systems and the like. Probes for hybridization may be synthesized by both enzymatic, and _in vitro techniques. Short hybridization probes are preferably synthesized by in vitro methodology such as the use of commercially available DNA synthesizers such as Applied Biosystems 1 " machines. An additional use for nucleic acid hybridization probes involves their use as primers for the polymerase chain reaction (PCR) . The polymerase chain reaction is described in detail in U.S. Patents 4,965,188 and 4,683,202 and 4,800,195. (iv) Production of cdσ Operon Proteins The nucleotide sequences of the edg operons being provided for, as well as the amino acid sequences of the polypeptides encoded by cdα operons, the present invention enables the production of purified edg operon encoded proteins by recombinant DNA expression techniques and by both in vitro polypeptide synthesis techniques and by is vivo production. Automated equipment for the direct synthesis of polypeptides disclosed herein is commercially available. Such equipment provides convenient access to peptides of the invention, either by direct synthesis or by synthesis of a series of fragments that can be coupled using other known techniques. Other methods for synthesis of cdα operon proteins include the in vitro transcription of cdσ operon gene sequences coupled with the in vitro translation of the RNA transcripts thus produced. In vitro transcription systems are well known in the art. In vitro transcription systems typically involve the creation of nucleotide sequences in which the coding sequence of interest is located downstream from a strong promoter, such as promoters specific for SP-6 or T7 RNA polymerases, followed by the addition of an RNA polymerase .specific for the promoter, and substrates required for the reaction. Similarly, in vitro translation systems are well known in the art and may be used to produce edg operon protein from a variety of transcripts produced by in vitro transcription systems. Expression vectors may be used to express quantities of edg operon proteins in a variety of cell hosts. Detailed descriptions of many expression vectors and their use can be found, for example in Goeddel, Methods in Enzy ology. Vol. 185 (1990) Academic Press. Expression vectors contain promoters functional in the host of interest. The promoter may be operably linked to the coding sequence of a gene of interest so as to produce a translatable mRNA transcript encoding a edg operon protein. Expression vectors will generally have convenient restriction sites located near the promoter sequence so as to provide for the insertion of coding nucleic acid sequences. The promoters in suitable expression vectors in particular expression vectors-for use in eukaryotic cells, may be either constitutive or inducible. In addition to having promoter sequenc-es, expression vectors may contain various enhanc-er sequences and the like, included for the purpose of maximizing expression of edg operon proteins. The invention having been described, the following examples are offered to illustrate the subject invention by way of illustration, not by way of limitation. EXAMPLES I. Purification of Diαuanvlate Cyclase The enzyme was purified from Acetobacter 1499 essentially as described by Ross, et al. (Nature 325:279-281 (1987)). The GTP affinity column purification scheme used resulted in the isolation of 4 polypeptides bands that could be visualized by PAGE: band la, having an apparent molecular weight of about 80kDa, band lb, having an apparent molecular weight of 78kDa, band III, having an apparent molecular weight of 65 kdal, and band IV, having an apparent molecular weight of 59kDa. Bands la and lb were found to be produced by proteins having diguanylate phosphodiesterase activity. Bands III and IV were found to be produced by proteins having diguanylate cyclase activity. II. NH 3 - terminus amino acid sequence of diσuanvlate cyclase Peptides were analyzed by automated Edman degradation on an Applied BioSyste s, Inc. Model 470A Sequenator. Analysis of band III, i.e., the 65 kdal polypeptide band, gave no sequence, indicating that the N-terminal residue was blocked. Treatment of the peptide sample with trifluoracetic acid in order to deblock an acetylation or hydrolyze the formyl group on a terminal N-formyl methionine failed to render the sample capable of being sequenced directly. The band III peptide was then subjected to partial digestion by oxidation with performic acid (Hirst J_j_ Biol. Chem. 19:611 (1956) and Moore J. Biol. Chem. 238:235 (1963). The preparation was then dialyzed against 0.1% TFA/25% CH 3 CN/H 2 0 and dried. The preparation was then incubated 4 hours at 40'C in lOOμl 6M guanidine chloride, 98/il 0.05M Tris pH 9.1, 2 jil lysyl endopeptidase from Achromobacter (200 g/400 βl in 0.022 mM Tris pHδ.l). The peptides from the digestion were subsequently separated by HPLC on a C4 reverse- phase column D-l elution with a gradient of 0 to 70% solvent B, where solvent A is 0.1% TFA in H 2 0 and B is 0.085% TFA/85% CH 3 CN/H 2 0. The peptides in 5 column fractions were εequenced. The sequence of fraction 50 was particularly useful.

PCR Generation of Oligonucleotide Probes For Cloning of Diαuanvlate Cyclase On the basis of the amino acid sequence information obtained from fraction 50 (Run 904), pools of oligonucleotides corresponding to amino acids 7 to 11 (ALA GLU THR ASP THR) and amino acids 19 to 24 (GLY PHE ASN THR ALA) . The oligonucleotide pools are given in Table 2. Table 2 3' region 19 20 21 22 23 24 GLY GLY PHE ASN THR ALA GGT GGT TTT AAT ACT GC C C c c C A A A G G G Oligonucleotide Probes Table 2 ( cont. ) 5 * region 7 8 9 10 11 ALA GLU THR ASP THR GCT GAA ACT GAT AC C G C C A A G G Oligonucleotide Probes Cel-1 GCT GAA ACT GAT AC C G C A G Cel-2 GCT GAA ACC GAT AC C G C A G Cel-3 GCT GAA ACA GAT AC C G C A G Cel-4 GCT GAA ACG GAT AC C G C A G Various combinations of the oligonucleotide pools were used as PCR primers in a PCR amplification of Acetobacter 1306-3 DNA. As the distance between amino acids 7 and 24 is 53 nucleotides, pools containing specifically binding nucleotide primers would be expected to produce a 53 base pair DNA product upon amplification by PCR. The 53 bp amplified sequence would be expected to be an exact match for a diguanylate cyclase encoding gene. PCR amplification was carried out in a volume of 50 μl in 3mM MgCl 2 , lO M Tris pH8.3, 50 μM KC1, 100 μg lml gelatin, 200 μM each dNTP, 500 μM primer (downstream) , 50-500 μM of primer (upstream) , 2 units Tag polymerase. Following heat denaturation of the template at 93 * C, the reactions were allowed to cool to 35"C for annealing. The temperature was then raised to 68 * C for 30 seconds for DNA synthesis. The temperature was then raised to 93 * C again for denaturation. The reaction cycle was repeated 15-30 times. Primer pool combinations Cel-2 + Cel-5 and Cel-2 + Cel-8 produced a 53 bp DNA band as visualized by gel electrophoresis . IV. Cloning of Diguanylate Cyclase A gene bank of Acetobacter 1306-11 was constructed in the broad host range, mobilizable cosmid pKT230C0S5. The average size of the cosmid insert is about 30 Kb. The gene bank contained about 2000 clones. Hybridization Conditions for Probing of the Cosmid Bank with 53 bp PCR Product The cosmid bank was probed as follows: Nitrocellulose filters containing plasmid DNA from approximately 2000 clones were first pre-hybridized at 42 * C for 1% hours in a solution containing 6X SSC, 5X Denhardt solution, 50 M NaP0 4 pH 6.5, 40% formamide and 100 ug/ml sheared salmon sperm DNA. This solution was replaced with a similar hybridization solution that contained only 20 ug/ml of sheared salmon sperm DNA. The 53 bp probe was end labeled with gamma ^P ATP to 2.16xlO β cpm/pmole and 4.17X10 7 cpm of the boiled probe were added to 50 mis of hybridization solution. The filters were incubated at 60'C for 3 hr. The filters were then washed once with 5X SSC + .1% SDS solution at room temperature for 5 min. , once with 2X SSC + .1% SDS at 60 * C for 10 min., and twice with IX SSC + .1% SDS at 60 * C for 10 and 30 min. respectively. The filters were exposed to Kodak ® XAR film for 1 hr. and positive clones were scored. The cosmid clones were streaked on R2-4 plates containing Str at 50 μg/ml. Three unique cosmid classes were identified and are represented by the cosmids 6C5, 3F3, and 15A8. 6C5 contains the cdg2 operon, 3F3 contains the cdgl operon, and 15A8 contains cdg3 operon. Clones 3F3 and overlapping 12A7 were studied for further analysis. Restriction analysis of 3F3 and 12A7 revealed that* the inserts overlapped; both clones contained a 1.7 Kb and 1.6 Kb PstI fragment that hybridized to Cel-21. Also isolated were clones 15A8 and 6C5. 15A8 contains a 2.3 kd Pst I fragment that hybridizes to Cel-21. Clone 6C5 contains a single 2.6 Kb Pst I band that hybridizes to Cel-21. PCR amplification of the various clones with the primers Cel-14 and Cel-8, or Cel-2 and Cel-8, revealed a 53 bp product only with clone 6C5, indicating that clone 6C5 contained a diguanylate cyclase gene subsequently identified as the dgc2 gene. Subsequently the clone was found to contain only part of the dgc2 gene. Cloning of Diguanylate Cyclase Gene In order to clone the complete dgc2 gene and other dgc genes, a second gene bank, prepared from Acetobacter 1306-3 was screened. The gene bank was prepared and screened essentially as described for the isolation of clones 6C5, 3F3, and 15A8. Cel-18 was used as a hybridization probe. Six clones, 5C10, 1301, 13G6, 22D6, 16G3 and 21B4 were isolated. Pst I and Hinc II restriction digests indicated that T16G3 and T21B4 are similar to each other, the remaining four clones are also similar to each other, but not to the other two clones. PCR amplification was used to confirm the presence of the diguanylate cyclase gene. PCR was performed using Cel-15 as the 5' primer and Cel-8 as the 3' primer under conditions as described in section III. 5C10 and 13D1 contained an intaet diguanylate cyclase gene. V. Cloning of Diguanylate Phosphodiesterase Genes N-terminal Amino Acid Sequence of Diguanylate Phosphodiesterase A Acetobacter 1306-21 was used for the purification. Growth conditions and medium are as described in Section XII for "seed cultures". About 9 gms of cells (dry weight) were centrifuged and washed twice with TME (50m Tris pH 7.5, lOmM MgCl 2 , 1 mM EDTA) , then the cells were suspended in the same buffer plus 20% polyethylene glycol and broken in a french press. The disrupted cells were centrifuged and the supernatant of the second wash was loaded onto a 2 ml GTP-agarose column. The supernatant of the first wash was discarded due to the presence of significant amounts of band lb protein. The column was washed with 50 ml TME and 30ml 1 mM ATP, 20 ml 1 mM CTP, and 20 ml 1 mM 5'GMP, each in TME, followed by 30 ml TME. Diguanylate cyclase was eluted with 50 mM Tris, pH 7.5, 10 mM MgCl 2f 10 mM EDTA, 200 M KC1. After washing with 9 ml TME, the PDEA was eluted with 15 ml 2 mM GTP in TME. SDS PAGE showed that the majority of the PDEA eluted between 2 to 7 ml. These five ml were pooled and concentrated in an Amicon Centricon 10 concentrator to 0.5 ml. Protein was estimated relative to BSA on SDS PAGE to be roughly 9 μg. This sample was dried to 10 μL in a Speed Vac, subjected to SDS PAGE, and transferred to a PVDF membrane. The top and bottom halves of the PDEA band were cut out and submitted separately for N- terminal amino acid sequencing. The final purification exploited the observation that PDEA binds more tightly to the cell membranes than do other proteins, allowing a starting preparation containing a smaller amount of contaminating proteins. Additional separation was obtained by eluting the column first with 200 mM KC1, which also removed a significant amount of the Band lb protein. Furthermore, division of the transferred protein band into halves helped to remove the contribution of the Band lb protein to the final sequence. Band lb migrates just below the PDEA on SDS-PAGE and thus could overlap with the bottom of the PDEA band. This overlap could be seen in the presence of a contaminating initial Met in the sequence from the bottom half, which is not present in the top half. Each of the three modifications significantly reduced the recovery of the protein. An Applied Biosystems, Inc., Model 470A Sequenator was used to determine the NH 3 -terminal amino acid sequence of the band la protein. The NH 3 -terminal sequence was determined to be: NH 3 Pro Asp lie Thr Ala Leu Thr Thr Glu lie Leu Leu Pro Ala Leu Glu Arg Ala - COOH Cloning of Phosphodiesterase A Oligonucleotide hybridization probes were designed based on the first 5 amino terminal amino acids of purified phosphodiesterase. Table 3 is a summary of the oligonucleotide probe pools synthesized. Oligonucleotide pools Cel-117 through Cel-120, each containing 24 sequences, represent all possible codon combinations for the first four amino acids and the first 2 bases of alanine. Oligonucleotide pools Cel- 121 and Cel-122 were also designed based on the N- terminal amino acid sequence, but the third codon positions were limited to G and C in Cel-121 and A and T in a Cel-122. The pools were kinased with ^P-ATP to a specific activity of approximately lxlO 7 cpm/pmole. The kinased probe pools were used to hybridize against dot blots of Acetobacter 1306-3 chromosomal DNA. The dot blots were prepared by digesting 100 μg of 1306-3 chromosomal DNA with Pst I. The DNA was ethanol precipitated and resuspended in a solution containing 85 μl of 100 mM Tris pH 74, 15 μl of 2N NaOH and 50 ml 20xSSC. The DNA was incubated at 80"C for 10 minutes, 20 μl of 2M Tris pH 7.4 was added. 10 μl of solution were spotted onto a nitrocellulose filter. 2-fold serial dilution were made and spotted onto the filter; thus, 5.88, 2.9, 1.-47 and .07 μg of DNA were spotted. Each row of 5 DNA samples was spotted six times. The filter was subsequently baked under a vacuum at 80 * C for 1 hr. The filter was cut into strips, 1 row per strip. Each strip was separately probed with a single oligonucleotide pool. lxlO 6 counts/ml of hybridization solution was added, hybridization was allowed to proceed overnight at 40'C. The filters were subsequently washed with 50 mis each with 5xSSC + 0.1% SDS at room temperature for 10 minutes, 2xSSC + 0.1% SDS at 40"C for " 15 minutes, and lxSSC + 0.1% SDS at 40 * C for 15 minutes. Autoradiography revealed that Cel-121 hybridized the most strongly, while Cel-119 hybridizing somewhat more weakly. Pools Cel-118 and Cel-120 hybridized extremely weakly. Based on the hybridization information, subpools Cel-129 to Cel-134 were designed based on Cel- 121, and subpools Cel-123 to Cel-128 were designed based on Cel-119. The subpools were used as hybridization probes for dot blots essentially as above. Cel-121 and Cel-123 appeared to hybridize the most strongly. Another gene bank prepared from Acetobacter 1306-3 genome DNA inserted in the vector PUC18-824 described in U.S. patent application 07/689,008, filed April 22, 1991 was probed with a combined probe of labeled Cel-121 and Cel-123 in essentially the same way as the hybridization probing for dgc genes was performed. Approximately 5000 E. coli colonies were screened by hybridizing against replica plated nitrocellulose filters using essentially the method of Grunstein and Hogness, Proc . Natl. Acad. Sci. USA, 72:3961 (1975) . The filters were probed with ^p-ATP labeled Cel-121 and Cel-123. The probe was labeled by kinasing to a specific activity level of 5xl0 6 cpm/pmole. lxlO 6 cpm/ml of hybridization solution of each probe was added and hybridization/washing was performed essentially the same as the way in which the dot blot hybridization was performed. Six strongly hybridizing independent clones were isolated. Restriction mapping of the 6 clones revealed that all were siblings. One clone, PDEA-7A was selected for further analysis. Southern blot analysis revealed that Cel-121 hybridized to a .8 Kb Pst I fragment of PDEA-7A, and no other PstI -fragments. The PstI fragment was subsequently subcloned and sequenced. A PDEA Gene Is Present on Cosmid Clone pKT230cos5-3F3 Nucleotide sequence determination of the pdeA on PDEA-7A revealed that a PDEA encoding gene, i.e., pdeAl . was present on 3F3, a cosmid clone isolated during the cloning of dαcl. To determine whether other homologous genes are present in the genome of strain 1306-3, Southern blot analysis was performed on chromosomal DNA isolated from strain 1306-3. 2 μg aliquots of DNA were digested with a variety of restriction enzymes, separated by electrophoresis 1% agarose gel, transferred by electroblotting to a nylon GeneScreen* membrane and probed with a radiolabeled PDEA-7A 3 Kb EcoRI fragment containing the PDEA gene. 200 ng of the DNA fragment were labeled with T4 DNA polymerase using ^P dCTP as the labelled nucleotide. The probe was then used at 1X10° cpm/ml essentially under GeneScreen ® manufacturer conditions, except that 40% formamide was used and the hybridization temperature was 40"C. These conditions allowed for detection of sequences in the genome that are somewhat homologous to pdeAl. The Southern blot results suggest that there are at least 3 and as many as 6 to 7 of homologous sequences in the genome. vi. Disruption of the pdeAl gene The cdgl operon is located on cosmid 3F3. The cosmid was mapped by restriction analysis followed by Southern blot analysis. Convenient restriction sites were utilized to disrupt dgcl and pdeAl by insertion inactivatio . The 4.2 Kb EcoRI fragment of 3F3 was subcloned into the EcoRI site of the plasmid pACYC184. Chloramphenicol (Cam) sensitive clones were isolated and DNA was prepared from this clone. This plasmid DNA was partially digested with EcoRV and the linearized DNA was ligated to an EcoRI to AlwNI fragment containing the β- lactamase gene isolated from pBR322 after its sticky ende were repaired by T4 DNA polymerase. Clones resistant to both ampicillin (Amp) and tetracycline (Tet) were identified in which the 0-lactamase gene was inserted between the EcoRV sites located at nucleotides 1855 and 1873 (SEQ ID N0:1) causing a gene disruption almost half way from the N-terminus. The resultant plasmid was linearized with BamHI and the DNA was used to transform strains 1306-3 and 1306-21 by electoporation. The resultant transformants were isolated from R20-2 + 100 μg/ l Amp plates. This transformant was designated 1306-21:Disl. All 1306-21 transformants were uniformly Cel + . Isolates were grown in R20-2 + 100 μg/ml Amp and their chromosomal DNA was purified. This DNA was digested with PstI or HincII+Bαlll and the DNA was analyzed by Southern blot. 3 μg of the digested DNA were resolved on an agarose gel, blotted onto Zeta-probe™ filters (BioRad) and probed according to the manufacturer instructions with the 4.0 Kb EcoRI fragment containing the pde l gene. The results suggest that strain 1306-21:Disl is disrupted as expected in the pdeAl gene. In addition to hybridizing to the expected pdeAl restriction fragments, the pdeAl probe also hybridized to other phosphodiesterase genes, such as pdeA2. Cellulose synthase, diguanylate phosphodiesterase A, and diguanylate cyclase assays were performed on the mutants. (See tables 5-9 for results). The results suggest that the disruption of pdeAl resulted in 80-90% reduction of both phosphodiesterase and diguanylate cyclase activities in these recombinant strains. The results also suggest that disruption of pdeAl gene has a polar effect on the expression of dgcl gene. The cellulose production of these strains was reduced by 30- 40%. In addition to the gene disruption described above in which the pdeAl gene was disrupted by inserting the amp gene between the EcoRV sites on 3F3, a similar disrupted mutant was constructed by inserting the str gene isolated from the broad host range plasmid pKT230. The fragment containing this antibiotic resistance gene was isolated from the plasmid pNV16 by digestion with Hind.HI and BamHI. After the fragment ends were repaired with T4 polymerase and dNTPs, the fragment was ligated between the two EcoRV sites located in pdeal. The disrupted gene was then introduced into strains 1306-21 and 1306-3 by the gene replacement method described above; these transformants were designated 1306-21:ABT3 and 1306-3:ABT3, respectively. VII. Disruption of the cdg2 operon The diguanylate cyclase gene, dgc2, was disrupted by insertion of a beta-lactamase- gene into the EcoRV site. An inactivating genetic construction with the disrupted gene was introduced into Acetobacter 1306-21 by electroporation. Southern blot analysis of ampicillin resistant strains confirmed that the endogenous intact dgc2 gene was replaced with the disrupted one. These strains retained a Cel + phenotype on plates. Western- blot analysis showed that these strains lacked Band IV. An inactivating genetic construction was made by inserting a disrupted diguanylate cyclase gene, dgc2. in the plasmid pACYC184 as follows. The dgc2 gene was isolated from the plasmid III531-1 as a HindlH-BamHI fragment and cloned in the EcoRV site of the plasmid pACYC184. The plasmid pACYC184 cannot replicate in Aσetobacter and served as a suicide vector. The beta lactamase gene was isolated from the plasmid pBR322 as an EcoRI-AlwNI fragment. This fragment was repaired with Klenow and cloned in the EcoRV Bite of the dgc2 gene in the suicide plasmid. The EcoRV site is located near the middle of the coding region of the cyclase gene. Two plasmids were obtained in which the beta lactamase gene is oriented in either direction with respect to the dgc2 gene, i.e., inactivating genetic constructions. They were designated TRT146-2 and TRT146-4. The beta lactamase gene is in the same transcriptional orientation as the chloramphenicol resistance gene in TRT146-4. 10 micrograms of each plasmid were digested with EcoRI and washed with H 2 0 in a Centricon spin tube. In addition, 10 micrograms of uncut DNA of each were washed. These DNAs were used to transform about 10 10 cells of 130-6-21 by electroporation. The transformation mix was grown in 1 ml of R20-2 at 30"C for 1 hr. and plated on R20-2 plates containing 50 micrograms of Amp. The plates were incubated at 30'C for 5 days and scored. Single colonies from each transformation were picked and streaked on R20-2 plates containing 50 micrograms of ampicillin. The strains containing plasmids TRT146- 2 and TRT146-4 were designated 1306-21:TRT150-1 and 1306-21:TRT151-1, respectively. Chromosomal DNA was prepared from these isolates. Chromosomal DNAs from four transformants and from the wild type strain 1306-21 were digested with Hindi or with Hindlll+Smal. Southern blot analysis was performed according to standard procedure. Two identical panels were probed either with a dgc2 specific probe, CEL30, or a beta-lactamase specific probe, AE108. All four transformants contained a disrupted gene instead of the intact gene. No gene duplication occurred when the intact plasmid was used, suggesting that the gene replacement must have occurred in two recombinational steps. VIII. Disruption of dgcl In order to produce an inactivating genetic σonstuct for dgcl, a 3.5 Kb StuI fragment from cosmid 3F3 was cloned into the EcoRV site in the tet resistance gene of pACYC184. Tet sensitive £_._ coli isolates were screened and a plasmid containing the insert was prepared and was partially digested with Nrul (a unique Nrul restriction site exists very close to the 5' end of dgcl) . The linearized full length plasmid DNA was ligated to the blunt-ended fragment containing the beta-lactamase gene of pBR322. Colonies that were resistant to amp and cam (chloramphenicol) were analyzed and two plasmids containing the interrupting amp gene in either orientation in the Nrul site in dgcl were identified. Each plasmid was linearized by digestion with BamHI and used to transform strains 1306-21 and 1306-3. The phenotype of all transformants was uniformly Cel + . Two independent isolates containing the inserted beta- lactamase gene in opposite orientations were grown in R20-2 + 100 μg/ml Amp. These- recombinant strains were grown in 150 ml of R70-2 + 100 μg/ml ampicillin and chromosomal DNA was prepared. The DNA from these strains was then isolated and digested with P_s_£I or StuI. and run on a gel. These strains were named Dis4 mutants. To ascertain that the Acetobacter recombinant strains obtained resulted from a gene replacement event in dgcl in the cdg2 operon, a genomic Southern blot analysis was performed. Chromosomal DNA was prepared and analyzed essentially as described above except the probe was hybridized at 55"C. The results show that dgcl was disrupted, but not dgc2 DNA from the recombinant strain was probed by a dgc2 specific probe to ascertain that the disrupted copy has not recombined into the highly homologous cdg2 locus. The dgc2 probe was isolated from a plasmid pTRT93-3 by preparing a 2090bp Hindlll to Hindi fragment containing dgc2. starting at the ATG, nucleotide 2465 and extending to nucleotide 4555 [SEQ. ID NO: 2] which contained an engineered Hindlll site in front ,of the dgc2 initiation ATG. The probe was labeled with T4 polymerase as described by O'Farrel, P. (1981) Focus 3 (Bethseda Research Laboratories, MD) , and hybridization was at 55 * C. Strain Dis4 and the recombinant strain TRT 150- 1, that is disrupted in dgc2 and consequently lacking the 57 Kd DGC2 peptide as determined by western analysis, were subjected to a genomic Southern blot analysis for comparison purposes. The results suggest that the interrupted dgcl copy did not recombine into the dgc2 locus. In a separate Southern blot analysis, chromosomal DNA was probed with the same dec2 probe under hybridization " conditions less stringent than prescribed by Zeta-probe M , i.e., at 50 * C. In this genomic Southern analysis the dαc2 probe not only hybridized to dgc2 in the cdg2 operon but also to dgcl in the cdgl operon. The fragments that the probe hybridized are consistent with the restriction map of the cdgl and cdg2 operons. IX. Disruption of The cdg2 Operon and Simultaneous Disruption of Both cdαl and cdg2 Operons To inactivate the cdg2 operon, a 1.5 Kb PstI fragment spanning pdeA2 and dgcl was deleted from the plasmid pRT93-4, which contains the 5.6 Kb Hindlll to Smal fragment from cosmid 6C5. The resulting 4.1 Kb fragment was introduced between the Hindlll and EcoRV sites in pACYC184. Tetracycline sensitive clones were identified and DNA was prepared in £_ • - coli. The plasmid DNA was linearized with PstI f the ends were repaired and ligated to the fragment containing the amp resistance gene. Amp resistant clones were isolated and plasmid DNA was prepared, linearized with BamHI and introduced into strains 1306-3 and 1306-21 and also into the same strains containing the str disrupted cdgl. i.e., ABT3 strain (see Section VI). The transformants were obtained by plating on R20-2 + 100/μg Amp and 80 μg/ml Str colonies of these double mutants are phenotypically Cel + '\ The double operon mutant strains containing disruptions in pdeAl, pdeA2. and dgc2 were designated ABT1 strains. Strains containing only a deletion and gene disruption of cdg2 are phenotypically Cel + . These strains containing disruptions only in the pdeA2 and dgc2 genes were called ABT2 strains. Construction of Double Operon Mutants The 5.6 Kb S al to ϋ n^III fragment from the cosmid 6C5, which contains σdg2, was purified by gel electrophoresis and ligated to a purified Hindlll to EcoRV fragment from plasmid pACYC184. The ligation mixture was sed to transform JL. coli MM294. The cells were plated on R2-4 plates containing 40 μg/ml Cm. Clones that were both Cam resistant and Tet sensitive containing the fragment DNA were identified. Plasmid DNA prepared from one such clone was linearized at the Bglll site located within the pdeA2 gene. The ends were repaired with T4 DNA polymerase. Approximately 400 ng of this 9.8 Kb fragment were ligated to approximately 400 ng of the 1.4 Kb EcoRI to AlwNI repaired beta- lactamase gene described above. The ligation mixture was used to transform £_ ^ coli MM294; Amp and Cm resistant colonies were isolated. Mini-prep DNA from one such colony was analyzed by restriction digests to confirm the insertion of the amp gene in the coding region of pdeA2. The rest of the mini-rep DNA (2-5 μg) was linearized with BamHI and was used to transform strains 1306-3, 1306-21, 1306-3:ABT3 and 1306-21 :ABT3. The ABT3 mutants contain the Str R gene introduced into the Bgl II site of pdeA2. The resulting mutants/transformants were designated 1306-3 :ABT9, 1306- 21:ABT9, 1306-3:ABT11 and 1306-21 :ABT11 respectively. Phenotypically ABT9 mutants are Cel + while ABT11 double mutants are Cel +/" . A strain in which the amp gene was inserted between the Smal site upstream of the cdglA gene in cdgl operon was also made. This construction may have caused a disruption of the cdgl operon promoter. This strain was designated 1306-21 :ABT8. Its phenotype is Cel + on R20- 2 plates + 50 μg/ml Amp. X. Overexpression of DGCl in Acetobacter Attempts were made to overexpress dgcl in a mutant in which pdeAl was inactivated. Only 15% of the PDEA activity remains in the mutant 1306-21:Disl (see table 4). Experiments were performed to test whether overexpression of dgcl in this mutant may have a positive effect on cellulose production. A shuttle vector, pUC19-824:dgcl was constructed to effect the overproduction of dgcl. A 3.5 Kb jSϋλl fragment was isolated from the cosmid 3F3 which contains the cdgl operon. The StuI fragment contains approximately 350 bp of the 3 end of pdeAl and the entire dgcl gene. The StuI fragment was ligated into the Smal site of the shuttle vector pUC19-824. The ligation mixture was used to transform the E_,_ coli strain DG101. The transformation mixture was plated on R2-4 + 50 μg/ml Amp plates on nitrocellulose filters. The colonies were probed with the dgcl specific probe GE407 (5'- TGATCTGCTACGGGATAG-3' ) . Several positive clones were identified. Two clones, one containing the dgcl gene downstream from the lac promoter and the other in the opposite orientation were designated pUC19-824:dgcl&8 and #11, respectively. Diguanylate cyclase activity in these strains was constitutively expressed at about 10% of the level in 1306-21. Mini-prep plasmid DNA from clones was used to transfora the following strains: 1306-3, 1306-21, 1306-3:ABT3 and 1306-21:ABT3. These strains were designated 1306-3:ABT10, 1306-21:ABT10, 1306-3:ABT6 and 1306-21:ABT6/L1 and 1306-21:ABT6/S1, respectively. The 1306-21:ABT3 transformants has 2 colony phenotypes, large (LI) and small (SI) of the approximately 3000 1306-21:ABT3 transformants, 10 had a large colony phenotype) and the remaining had a small colony phenotype. Enzyme assays (see table 5) indicate that the level of DGC activity in 1306-21:ABT10 is approximately four-fold higher than Acetobacter 1306- 21. All other tested enzymatic activities in comparable to the 1306-21. XI. Biochemical Studies of cdαl and cdα2 Mutants Table 4 is a summary of recombinant Acetobacter strains with disruptions in the cdαl and cdg2 operons. Table 5 is a summary of PDEA and DGC activity in the mutant strains given in percent of the wild type levels. The last column of Table 5 indicates the ability of each recombinant strain to inhibit the activation of cellulose synthesis relative to the inhibition in mutant 1306-21:Disl. The results indicate that cdαl operon codes for about 85% of PDEA and DGC activities and that cdg2 operon codes for 5-15% of PDEA and DGC activities. cdg3 operon probably codes for the remaining activities (1- 5%), because inacativation of cdgl and cdg2 operons results in 1 to 5% of PDEA and DGC activities. Extra copies of dgcl gene on pUC19-824 plasmid increase DGC activity by about 4 fold, compared to parent strain 1306-21.

Production of Cellulose in pdeA Mutant Strains The recombinant strains of Acetobacter were tested for alterations in cellulose production levels. The construction of strains with the P L promotor operably linked to the cellulose synthase operon is reported in U.S. Patent Application 07/689,008, filed April 22, 1991. Details on how to obtain cellulose from Acetobacter can be found in U.S. Patent 4,929,550 and U.S. patent application 07/604,587, filed October 26, 1990. The cellulose production of these strains was measured in flasks with Floxan EA-1340. The flasks were incubated at low agitation in order to provide the optimum conditions for cellulose production. All seed cultures were grown in R70-3 medium plus 0.5% (w/v) TYE, 25 mM DMG and 0.1% (v/v) cellulase (1, 2, 3 cellulase Genencor) . The 1306-21 seed cultures had 3% (w/v) glucose while the 1306-3 cultures were grown in 3% (w/v) fructose. The recombinant strains were grown in 100 ug/ml Amp. Some of the 1306-3 recombinant strains were originally isolated from relatively small or large colonies. These different isolates have the designation "small" or "large" respectively. The test medium for this experiment was R70-3 plus 1 g/L Floxan EA-1340, 2% (v/v) E801A corn steep liquor (CSL) (corn steep liquor, from Corn Products Inc., Ango, Illinois) and 25 mM DMG. All 1306-21 strains were grown in 10 g/L glucose, while all 1306-3 strains were grown in 10 g/L fructose. All recombinant strains were grown in the presence of 100 ug/ml Amp. The experiment was done in 125 ml baffled flasks (25 ml medium/flask) . The seed flasks were incubated at 30'C, 125 rpm overnight, and then the cell mass in each flask was determined by OD^ measurements. The 1306-21 test flasks received a 5% (v/v) inoculum, and the rest of the test flasks were given an inoculum of 3.5% to 9% so that all of the flasks would have the same cell mass at time 0. The test flasks were incubated at 30 * C, 125 rpm for three days, and then the cellulose and cell mass were determined using standard procedures. The results of the 1306-21 and 1306-3 cultures are given in Tables 6 and 7. All of the cultures had a final pH of 5.6-5.9. These high pH values have not been observed in previous glucose limited flask experiments. However, this experiment used E801A CSL, and E801A CSL media has relatively high levels of lactic acid. The high pH is most likely the result of the cells consuming the large amount of lactic acid. Table 6 shows that 1306-21 strains containing either pABCD or P L produced similar levels of cellulose. Plasmid pABCD or pL contain sequences encoding the cellulose synthase operon and express cellulose synthase in bacterial cells, see co-pending U.S. Patent Application No. 07/687,008 for details on construction of these plasmids. The results observed with the 1306-21 recombinant strains were not observed with the 1306-3 recombinant strains. Table 7 shows that the 1306-3 P L strain appears to produce less cellulose than the control. All of the 1306-3 cultures were grown in fructose in order to minimize pH problems. All of the putative PDEA gene disrupted strains (1306-21 Disl, 1306-21 Dis2 and 1306-3 Dis5) produced less cellulose than their respective controls. The 1306-21 putative PDEA disrupted strains also appeared to have a significant drop in the cellulose to cell ratio.

Seed cultures were grown up in R70-3 plus 25 M DMG, 30 g.L glucose, 0.5% (w/v) TYE and 0.1% cellulase. The test medium for all experiments was R70-3 plus 1% (v/v) E801A CSL, 1 g/L Floxan EA-1340, 10 g/L glucose and 25 mM DMG. All recombinant strains except 1306-21-.ABT3 has 100 ug/ml Amp in the seed and test flasks. Strain 1306- 21:ABT3 had 40 ug/ml Str in the seed and test flasks. All test flasks received a 5% inoculum, and the flasks were incubated for three days at 30"C, 250 rpm (1" throw) . The results of the experiments are given in Table 8. The largest drop in cellulose production can be found in the double dgcl/dgc2 mutant 1306-21-.ABT21. 1306- 21:ABT10 appeared to produce more cellulose than the - control. 1306-21:ABT10 has dgcl overexpressed in the -parental strain 1306-21.

Probes for edg Operons Inspection of the DNA sequence in cdα operons revealed that genes pdeAl. pdeA2. pdeA3. dαcl . dgc2. and dgσ3 share of highly homologous region of DNA. This region is contained within the 53 kb PCR. product described in Example III, that was used to locate the three edg operons. Table 9 describes the common region of homology with pdeA and dgc genes. The 53kb DNA probe can be used to indentify and clone edg operons in other Acetobacter strains, in cellulose synthesizing bacteria or in plant cells and other cellulose synthesizing species. The hydridization conditions to utilize this probe are described in Example 3. To identify genes in other organisms, less stringent hybridization conditions may be used, e.g., lower temperatures. Oligonucleotide regions specific to pdeA genes alone or to dgc genes alone were also identified. These probes include probes cel-141 GACAGCGAATCCCTGCTCA, and eel-142 CCGTGCATTTCCGCAAC, as specific probes for pdeA genes. These probes shared 100% homology within the three genes of pdeA. DNA probes TACTGGGTGGCCACCACC and CATGGCCACCATGCG located at nucleotide 3490 and 3760 of cdgl operon, respectively, as specific probes for dgc genes. These regions also share 100% homology within dgcl and dgc2 genes. These probes can be used to indentify corresponding pdeA and dgc genes in other organisms, as well as edg operons. The hybridization conditions used may vary from stringent conditions- for closely related strains and species, to less stringent conditions with more evolutionarily divergent organisms. Antiseram prepared against digopeptides encoded by these common, regions can be used to identify PDEA and DGC peptides in other organisms in addition to screening expression libraries.
