The invention also provides cross-linked elastins or elastin-like products prepared from the tropoelastins or variants.

Description: SYNTHETIC POLYNUCLEOTIDES TECHNICAL FIELD The present invention relates to the production of recombinant tropoelastins , and variants of these re c omb i nant t ropo e l a s t i ns , f rom s yn t he t i c polynucleotides , and uses of the tropoelastins and variants . BACKGROUND ART There are various forms of tropoelastin that typically appear to consist of two types of alternating domains : those rich in hydrophobic amino acids (responsible for the elastic properties) and those rich in lysine residues (responsible for cross-link formation) . Hydrophobic and cross-linking domains are encoded in separate exons (Indik et al . , 1987) . The gene for tropoelastin is believed to be present as a single copy in the mammalian genome, and is expressed in the form of multiple transcripts, distinguished by alternative splicing of the pre-mRNA (Indik et al , 1990; Oliver et al, 1987) . Previous recombinant work with tropoelastin has been reported by Indik et al (1990) who achieved modest expression of a natural human tropoelastin sequence from cDNA. Their product was unstable, the free polypeptide being rapidly degraded. Bressan et al (1987) have reported the cloning of a defined naturally occurring segment of chick tropoelastin. DESCRIPTION OF THE INVENTION The present invention provides for the expression of significant amounts of tropoelastins or variants of the tropoelastins in recombinant expression systems . The present inventors have recognised that tropoelastins are proteins which can be used in a variety of, for instance, pharmaceutical applications, but these uses require significant quantities of tropoelastin. These quantities could be obtained by cloning naturally occurring tropoelastin genes, but the present inventors show how they can be more easily obtained by producing synthetic polynucleotides adapted to provide enhanced expression. The present inventors have recognised that because tropoelastins have highly repetitive coding sequences, the tropoelastin genes have the potential to include significant numbers of codons which have low usage in particular hosts. Codons of low usage can hamper gene expression. For example, in one tropoelastin coding sequence described in detail in this application, the natural sequence contains of the order of 80 glycine GGA codons which comprises 10% of the gene and have low usage in Escherichia coli [Fazio et al . , 1988, and Genetics Computer Group (GCG) package version 7-UNIX using Codon Frequency and Gen Run Data: ecohigh-cod] . According to a first aspect of the present invention, there is provided a synthetic polynucleotide encoding the amino acid sequence of a tropoelastin or a variant of the tropoelastin. The tropoelastin may be a mammalian or avian tropoelastin such as human, bovine, ovine, porcine, rat or chick tropoelastin. Preferably, the tropoelastin is human tropoelastin. The synthetic polynucleotide sequence is altered with respect to the natural coding sequence for the tropoelastin molecule or variant so that: a) it codes for a tropoelastin sequence or a variant of the tropoelastin.; and, b) all or some of the codons which hamper expression in the expression system in which the polynucleotide is to be expressed, are replaced with codons more favourable for expression in the expression system. Preferably all, or part, of the 5' or 3' untranslated regions, or both, of the natural coding sequence are excluded from the synthetic polynucleotide. Preferably all, or part, of the signal peptide encoding region is excluded from the synthetic polynucleotide . Where the synthetic polynucleotide is prepared from assembled oligonucleotides it is preferred to incorporate restriction sites in the sequence to facilitate assembly of the polynucleotide. Restriction sites incorporated in the polynucleotide sequence are also useful for: 1. facilitating subcloning of manageable blocks for sequence confirmation; 2. providing sites for later introduction of modifications to the polynucleotide as insertions, deletions or base changes; 3. facilitating confirmation of correct poly¬ nucleotide assembly by restriction endonuclease digestion. A preferred expression system is an Escherichia coli expression system. However, the invention includes within its scope synthetic polynucleotides suitable for use in other expression systems such as other microbial expression systems. These other expression systems include yeast and bacterial expression systems, insect cell expression systems, and expression systems involving other eukaryotic cell lines or whole organisms. Modifications to codon usage to provide enhanced expression are discussed in: Zhang et al (1991) for E. coli , yeast, fruit fly and primates where codon usage tables are provided; Newgard et al (1986) for mammals; and Murray et al (1989) for plants. Preferred codon usages are indicated in these publications. Preferably, at least 50% of codons for any particular amino acid are selected and altered to reflect preferred codon usage in the host of choice. Preferably, the polynucleotide is a fused polynucleotide with the tropoelastin or variant encoding sequence fused to a polynucleotide sequence compatible with the host. The compatible sequence is preferably at the 5 ' end of the polynucleotide molecule . Preferred compatible polynucleotides include those which encode all or part of a polypeptide which causes the expressed fusion to be secreted or expressed as a cell surface protein so as to facilitate purification of the expressed product, or expressed as a cytoplasmic protein. One preferred compatible polynucleotide is one encoding all or part of glutathione-S-transferase. In addition the synthetic polynucleotides can encode additional residues such as an N-terminal methionine or f-methionine not present in the natural counterpart. A preferred synthetic polynucleotide is one comprising the sequence illustrated in Figure 3 (1) to 3 (5) (SEQ ID NO 1) or a part of it, encoding a polypeptide which retains elastic properties. The sequence illustrated in Figure 3 (1) to 3 (5) is 2210 bp in size. To our knowledge, this is the largest synthetic gene constructed so far. Previously, the largest was of the order of 1.5 kb in size. The actual changes made in this sequence in comparison with the natural sequence from which it was derived are shown in Figure 6 (1) to 6 (4) comparing the synthetic sequence (SEQ ID NO 1) with the natural sequence (SEQ ID NO 53) . Synthetic polynucleotides in which only some of the base changes shown in that Figure have been made are also within the scope of the invention. It is known that tropoelastin genes in nature are ex ressed, as... multiple transcripts which are distinguished by alternative splicing of the pre-mRNA as described in, for instance: Indik et al , 1990; Oliver et al, 1987; Heim et al, 1991; Raju et al , 1987; and Yeh et al, 1987. The tropoelastins of the present invention for which synthetic polynucleotides are prepared are intended to encompass these different splice forms. Variants of tropoelastins embodying the present invention are polypeptides which retain the basic structural attributes, namely the elastic properties, of a tropoelastin molecule, and which are homologous to naturally occurring tropoelastin molecules. For the purposes of this description, "homology" between two sequences connotes a likeness short of identity indicative of a derivation of one sequence from the other. In particular, a polypeptide is homologous to a tropoelastin molecule if a comparison of amino-acid sequences between the molecules reveals an identity of greater than about 65% over any contiguous 20 amino acid stretch or over any repetitive element of the tropoelastin molecule shorter than 20 amino acids in length. Such a sequence comparison can be performed via known algorithms, such as the one described by Lipman and Pearson, Science 227 : 1435 (1985) which are readily implemented by computer. Variants of tropoelastins can be produced by conventional site-directed or random mutagenesis. This is one avenue for routinely identifying residues of the molecule that can be modified without destroying the elastic properties of the molecule. Oligonucleotide-directed mutagenesis, comprising: 1. synthesis of an oligonucleotide with a sequence that contains the desired nucleotide substitution (mutation) , 2. hybridizing the oligonucleotide to a template comprising a structural sequence coding for tropoelastin and 3. using a DNA polymerase to extend the oligonucleotide as a primer, is preferred because of its- ready utility in determining the effects of particular changes to the structural sequence. Its relative expense may militate in favour of an alternative, known direct or random mutagenesis method. Another approach which is particularly suited to situations where the synthetic polynucleotide has been prepared from oligonucleotide blocks bounded by restrictions sites is cassette mutagenesis where entire restriction fragments are inserted, deleted or replaced. Also exemplary of variants within the present invention are molecules that correspond to a portion of a tropoelastin molecule without being coincident with a natural tropoelastin molecule and which retain the elastic properties of a natural tropoelastin molecule. Other variants of tropoelastins of the present invention are fragments that retain the elastic properties of a tropoelastin molecule. Fragments within the scope of this invention are typically greater than 20 amino acids in length. According to a second aspect of the present invention there is provided a recombinant DNA molecule comprising a synthetic polynucleotide of the first aspect, and vector DNA. Vectors useful in the invention include plasmids, phages and phagemids. The synthetic polynucleotides of the present invention can also be used in integrative expression systems or lytic or comparable expression systems. Suitable vectors will generally contain origins of replication and control sequences which are derived from species compatible with the intended expression host . Typically these vectors include a promoter located upstream from the synthetic polynucleotide, together with a ribosome binding site for prokaryotic expression, and a phenotypic selection gene such as one conferring antibiotic resistance or supplying an auxotrophic requirement. For production vectors, vectors which provide tor enhanced stability through partitioning may be chosen. Where integrative vectors are used it is not necessary for the vector to have an origin of replication. Lytic and other comparable expression systems do not need to have those functions required for maintenance of vectors in hosts . Typical vectors include pBR322, pBluescript II SK + , pGEX-2T, pTrc99A, pET series vectors, particularly pET3d, (Studier et al; 1990) and derivatives of these vectors. According to a third aspect of the present invention there is provided a transformed host transformed with a recombinant DNA molecule of the second aspect . Hosts embodying the invention include bacteria, yeasts, insect cells and other eukaryotic cells or whole organisms. They are typically bacterial hosts. A preferred host is an E. coli strain. Examples of E. coli hosts include E. coli B strain derivatives (Studier et al , 1990) , NM522 (Gough and Murray, 1983) and XLl-Blue (Bullock et al, 1987) . Hosts embodying this invention, for providing enhanced expression of tropoelastin or tropoelastin variants, are those in which the altered codon usage is favourable for expression, and with which any control sequences present in the recombinant DNA are compatible. According to a fourth aspect of the present invention there is provided an expression product of a transformed host of the third aspect which expression product comprises a tropoelastin or a variant thereof. A preferred expression product of the fourth aspect comprises all or part of the amino-acid sequence depicted in Figure 3 (1) to 3 (5) (SEQ ID NO: 1) . The serine at position 1 may be deleted from the product and similarly the methionine at position 2 may be deleted. Other preferred expression products are those in which only some of the base changes shown in Figure 6 (1) to 6 (4) have been made. Typically at least 50% of the indicated base changes have been made. The expression products of the fourth aspect may be fused expression products which, include all or part of a protein encoded by the vector in peptide linkage with the expression product. They may also include, for example, an N-terminal methionine or other additional residues which do not impair the elastic properties of the product . Typically the fusion is to the N-terminus of the expression product. An example of a suitable protein is glutathione-S-transferase. The fused protein sequence may be chosen m order to cause the expression product to be secreted or expressed as a cell surface protein tc simplify purification or expressed as a cytoplasmic protein. The expressed fusion products may subsequently be treated to remove the fused protein sequences to provide free tropoelastin or a free tropoelastin variant. The expression products of the fourth aspect may also be produced from non-fusion vectors such as pND211 (N. Dixon, Australian National University) . This vector has the gene inserted into an Ncol site and uses lambda- promoter-driven expression to permit initiation from the start codon of the synthetic gene. The sequence of the vector is shown at Figure 9 (1) and 9 (2) (SEQ ID NO: 54) . Other suitable non-fusion vectors include pET3d. According to a fifth aspect of the present invention there is provided a pharmaceutical or veterinary composition comprising an expression product of the fourth aspect together with a pharmaceutically or veterinarally acceptable carrier. Dosage of the expression product and choice of carrier will vary with the specific purpose for which the expression product is being administered. The expression products of the fourth aspect may also be prepared in the form of foods or as industrial products where elastic or association properties may be desired. The tropoelastin expression products of the invention can form associations in solution wherein the tropoelastin molecules are held together by hydrophobic interactions. These associations are termed- "coacervates" . They are useful as precursors to elastin synthesis. The tropoelastin coacervates can also be used as delivery vehicles for active ingredients such as pharmaceutical or veterinary agents providing biodegradable or biodissociable slow release formulations or alternatively protective coatings to protect active agents, for instance, during their transit through the stomach of a hos . According to a sixth aspect of the present invention there is provided a process for the production of an expression product of the fourth aspect comprising: providing a transformed host of the third aspect; culturing it under conditions suitable for the expression of the product of the fourth aspect; and collecting the expression product . In one preferred form the expression product is produced in the form of inclusion bodies which are harvested from the transformed host . In a seventh aspect of the invention there is provided a cross-linked expression product of the fourth aspect. The cross-linked expression products form elastin or elastin-like products. In preparing a synthetic polynucleotide in accordance with the first aspect the following procedure is followed. A cDNA sequence encoding a tropoelastin, or a part of it, is selected and the open reading frame is defined. The sequence is then translated to provide the corresponding amino acid sequence. Alternatively, the procedure can commence from a known amino acid sequence. The exons which are to be included in the expression product are chosen. Preferably, any signal sequence or untranslated regions will not be included in the synthetic polynucleotide. The amino acid sequence selected is then converted to a polynucleotide sequence on the basis of codon usage frequencies. By selecting the most commonly used codon for each amino acid for the host in which expression is desired, a skewed usage arises because particular codons may have very different frequencies of usage. It is therefore necessary to adjust the codon usage of at least the most common codons, that is, those present at greater than 20 occurrences, to more closely match levels of codon usage in the host of choice. It is preferable to alter the sequence to introduce restriction sites at regular intervals throughout the sequence where these represent silent alterations, that is, they do not change the resulting amino acid. In addition ends suitable for ligation, eg BamHI and/or Ncol sites can be introduced into the sequence. Tropoelastin sequences described for various organisms are similar, particularly at the level of exon structure and the organisation of hydrophilic and hydrophobic domains. In selecting exons to be included in the expression product we have adopted an approach whereby we leave in exons known to occur in all available tropoelastins. Depending on the intended use of the resulting tropoelastin, additional exons, or synthetic sequences, or both, are included. For instance, in the human example provided we included exon 10A which only occurs in some of the known sequences for human tropoelastin. In the bovine case, a typical addition would be exons 4A, 6 and/or 9 (Raju and Anwar, 1987; Yeh et al, 1987) . In the rat case, a typical addition would be exons corresponding to exons 12 through 15 of the bovine case. (Heim et al 1991) . The construction of the synthetic polynucleotide of Figures 3 and 6 will now be described in more detail. The synthetic tropoelastin gene described here differs from the natural coding sequence (s) in a number of ways. The untranslated regions present in the tropoelastin cDNA sequence were disregarded in designing the synthetic gene, and the nucleotides encoding the signal peptide were removed. Restriction endonuclease recognition sites were incorporated at regular intervals into the gene by typically altering only the third base of the relevant codons, thereby maintaining the primary sequence of the gene product. The facility for silent alteration of the coding sequence was also exploited to change the codon bias of the tropoelastin gene to that commonly found in highly expressed E. coli genes. [Genetics Computer Group (GCG) package version 7-UNIX using Codon Frequency and Gen Run Data: ecohigh-cod] . Two additional stop codons were added to the 3 ' -end, and an ATG start codon comprising a novel Ncol site was appended to the 5 '-end. Bam HI cloning sites were engineered at both ends of the synthetic sequence. Since the gene contains no internal methionine residues, treatment of the newly-synthesized gene product (expressed directly or as a fusion with another gene) with cyanogen bromide would liberate a protein with the same or similar sequence as one form of natural tropoelastin comprising 731 amino acids. Other forms of processing are envisaged, which may generate tropoelastin species of the same or different lengths. Two stop codons were added in order to allow the possible use of the construct in suppressor hosts, and also to avoid any potential depletion of termination (release) factors for translation. The inclusion of an ATG site is useful because: (1) it provides an appropriate restriction site for cloning, although this is a flexible property; (2) it provides a potential start codon for translation of an unfused synthetic gene; and (3) it introduces a methionine which can be cleaved by cyanogen bromide to release the tropoelastin species. However, another method of cleavage would not necessarily rely upon the availability of this methionine. Fusion can provide a more stably expressed protein, and experience of other workers has suggested that unfused tropoelastin may be unstable (Indik et al . , 1990) . The fusion is typically to the carboxy terminus of the fusion protein (i.e. the N-terminus of the tropoelastin) . Glutathione-S-transferase (Smith and Johnson, 1988) is an example of a suitable fusion protein. A convergent approach was used in assembly and cloning of the synthetic human tropoelastin (SHEL) sequence. Groups of six, and in one case, eight, oligonucleotides were annealed and ligated together to generate eight synthetic blocks of approximately 260- 300bp, designated SHEL1-8. These blocks were cloned independently into pBluescript II SK + ; the assembly and cloning scheme for SHEL1 is illustrated in Figure i , Following sequence confirmation, the blocks were excised from their parent plasmids and used to construct three clones, pSHEL α,β and 7, each containing approximately 700-800bp of the synthetic gene. The final step towards assembly of the complete SHEL gene involved ligation of the inserts from each of these three intermediary clones into pBluescript II SK + to produce pSHEL. The cloning scheme is illustrated in Figure 2. The tropoelastin or variant produced as an expression product from vectors such as pSHEL can be chemically cross-linked to form an elastin product. Three available procedures are: 1. chemical oxidation of lysine side chains which are conducive to cross-linking [eg ruthenium tetroxide- mediated oxidation, via the amide (Yoshifuji S; Tanaka K; and Nitto Y (1987) Chem. Pharm Bull 35 . 2994-3000) and quinone-mediated oxidation] ; 2. homobifunctional chemical cross-linking agents, such as dithiobis (succinimidylpropionate) , dimethyl adipimidate and dimethyl pimelimidate. There are many other amine-reactive cross-linking agents which could be used as alternatives; and 3. cross-linking via lysine and glutamic acid side chains as taught by Rapaka et al (1983) . The tropoelastins or variants of the invention may also be enzymatically cross-linked to form an elastin or elastin-like product. Enzymatic methods include lysyl oxidase-mediated oxidation of the tropoelastin or variant via modification of peptidyl lysine [Beddell-Hogan et al (1993)] . Oxidised lysines participate in the generation of cross-linkages between and within tropoelastin molecules. Other modification enzymes can be used forming cross-links via lysine or other residues. Cross-linking can also be achieved by gamma irradiation using, for instance, techniques adapted from Urry et al (1986) . Tropoelastins or variants of the invention cross- linked to form elastin or elastin-like products are also within the scope of the invention. The half-lives of the products in free solution will determine the suitability of a particular agent for a particular application. For example, the hydrolytic breakdown of the cross- linked material will be useful in applications, such as surgical applications, where the gradual loss of material over time is intended.

BEST METHOD OF PERFORMING THE INVENTION The recombinant and synthetic techniques used are standard techniques which are described in standard texts such as Sambrook et al (1989) . Purification of the expression products is also performed using standard techniques, with the actual sequence of steps in each instance being governed by the host/expression product combination. The pharmaceutical and veterinary compositions are formulated in accordance with standard techniques. The amount of expression product that may be combined with carrier to produce a single dosage form will vary depending upon the condition being treated, the host to be treated and the particular mode of administration. It will be understood, also, that the specific dose level for any particular host will depend upon a variety of factors including the activity of the expression product employed, the age, body weight, general health, sex, diet of the patient, time of administration, route of administration, rate of excretion, drug combination, etc. The compositions may be administered parenterally in dosage unit formulations containing conventional, non- toxic, pharmaceutically and/or veterinarally acceptable carriers, diluents, adjuvants and/or excipients as desired. Injectable preparations, for example, sterile injectable aqueous or oleagenous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents . The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent . Among the acceptable vehicles or solvents that may be employed are water, Ringer's solution, and isotαnic sodium chloride- solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid and organic solvents find use in the preparation of injectables. Routes of administration, dosages to be administered as well as frequency of administration are all factors which can be optimised using ordinary skill the art. In addition, the expression products may be prepared as topical preparations for instance as anti-wrinkle and hand lotions using standard techniques for the preparation of such formulations. They may be prepared in aerosol form for, for instance, administration to a patient's lungs, or in the form of surgical implants, foods or industrial products by standard techniques . The tropoelastins can be cross-linked either chemically, enzymatically or by irradiation to form elastin products for use in applications such as pharmaceutical applications, surgical, veterinary and medical applications, cosmetic applications, and in industrial uses. Tropoelastin coacervates can be used to formulate slow release compositions of active ingredients or to form protective coatings for active ingredients using standard formulation techniques. Materials and Methods Materials Restriction enzymes, T4 polynucleotide kinase and T4 DNA ligase were obtained from Boehringer Mannheim, Progen ® Industries or New England Biolabs. Gelase was obtained from Epicentre Technologies. Reagents for solid-phase oligodeoxynucleotide synthesis were obtained from Applied Biosystems (ABI) . Low melting temperature (LMT) agarose was obtained from Progen or FMC and α-- 35 S-dATP was obtained from Amersham International. Plasmid vectors pBluescript II SK + and pGEX-2T were obtained from Stratagene and Medos Co Pty Ltd respectively. pET3d was obtained from F.W. Studier at Brookhaven National- Laboratory, NY, U.S.A. _____ coli strains HMS174 and BL21 (DE3) are described in Studier et al (1990) . Oligodeoxynucleotide Synthesis and Purification Oligonucleotides were synthesized on 40nmol-scale polystyrene-support columns on an Applied Biosystems 381A or 394 DNA synthesis machine. Standard ABI protocols were employed for synthesis, including chemical 5'- phosphorylation where appropriate. Detritylation was performed automatically, and cleavage from the solid support effected manually (381A) or automatically (394) according to the synthesizer used. Base protecting groups were removed by heating the ammoniacal oligonucleotide solution at 55-60°C overnight. Deprotected oligonucleotides were lyophilized, dissolved in 400μl TE buffer and ethanol precipitated prior to resuspension in lOOμl 50% deionized formamide in TE. All oligonucleotides used in construction of the sHEL gene were purified by denaturing PAGE before use. 160mm x 100mm x 1.5mm polyacrylamide gels containing 7M urea were used for this purpose. Short oligonucleotides (<40-mers) were purified on 20% gels whilst long oligonucleotides (>85-mers) were purified on gels containing 8-10% acrylamide (acrylamide :bisacrylamide 19:1) . Samples were heated to 75°C for 3 min before loading. Tracking dye (0.05% bromophenol blue, 0.05% xylene cyanole FF in deionized formamide) was loaded into an adjacent lane. Electrophoresis was conducted at constant power (17W) until the bromophenol blue marker was within 1cm of the base of the gel. The apparatus was disassembled and the gel wrapped in cling film. Product bands were visualized by UV-shadowing over a fluorescent TLC plate. Excised gel fragments containing purified oligonucleotides were transferred to microcentrifuge tubes, crushed and soaked overnight at 60°C in 500μl elution buffer (0.3M sodium acetate pH7.0) . A second extraction was performed with 400μl elution buffer, for 3-4h at 60°C and the supernatant combined with that of the first extraction. The total volume of the oligonucleotide-containing solution was reduced to approximately 400μl by butan-1-ol extraction and DNA precipitated by addition of 1ml ethanol . Purified oligonucleotide was pelleted by centrifugation, redissolved in 20μl TE buffer and quantified by spectrophotometry. The final yield of purified oligonucleotide obtained in this manner was typically 10- 30μg. Construction of Synthetic Gene 'Blocks' (sHELl-8) Complementary oligonucleotides (30pmol each, approx lμg for 95-mers) were annealed in lOμl buffer containing 50mM Tris.HCl pH7.5, lOmM MgCl 2 . The mixture was overlayed with 12μl paraffin oil, heated to 95°C and cooled slowly to 16°C (16h) in a microprocessor- controlled heating block (Perkin Elmer Cetus Thermal Cycler) . Annealed samples were transferred to clean microcentrifuge tubes and a small aliquot (lμl) withdrawn for analysis by agarose gel electrophoresis (2%LMT gel, TBE running buffer) . For each block comprising three complementary oligonucleotide pairs, four separate ligation reactions were set up. Each contained 50mM Tris.HCl pH7.5, lOmM MgCl 2 , ImM ATP, 3mM DTT, 3μl each of the appropriate annealed samples, 0.5μl (0.5U) T4 DNA ligase and Milli-Q water to a total volume of lOμl . All components except the ATP, DTT and T4 ligase were mixed and heated to 55°C for 5 min to denature cohesive termini and cooled to room temperature before addition of the remaining components. Ligation reactions were incubated overnight at 16°C and analysed on 2% LMT agarose gels, with TBE as running buffer. Ligated blocks were purified by preparative agarose gel electrophoresis using 2% LMT agarose gels with TAE running buffer. Product bands were identified under long-wave UV illumination with reference to known DNA size standards (pBluescript II SK + digested with Hae III) and excised in the minimum possible volume of gel . DNA was recovered from LMT agarose fragments using Gelase in accordance with the manufacturer's instructions ("fast" protocol^ . Purity, and yield o"f recovered sHEL blocks was assessed by analytical agarose electrophoresis alongside known DNA size standards. Block 8 was created by a slightly different strategy. The first 3 oligonucleotide pairs (numbers 22, 23, 24, 47, 48 and 49) were assembled and purified as described for blocks 1 to 7, after which the remaining oligonucleotide pair (numbers 25 and 50) was ligated under conditions described above. The full length block 8 was purified as described for blocks 1 to 7. The oligonucleotides used for preparing each of the blocks shown in Figures 4 (1) to 4 (2) and 5 (1) to 5 (2) were assembled as follows : B] .ock ÷strand Seq ID -strand Seq ID oligonuc] .eotideε oligonucleotideε 1 1,2,3 3 - 5 26,27,28 28 - 30 2 4,5,6 6 - 8 29,30,31 31 - 33 3 7,8,9 9 - 11 32,33,34 34 - 36 4 10,11,12 12 - 14 35,36,37 37 - 39 5 13,14,15 15 - 17 38,39,40 40 - 42 6 16,17,18 18 - 20 41,42,43 43 - 45 7 19,20,21 21 - 23 44,45,46 46 - 48 8 22,23,24, 25 24 - 27 47,48,49, 50 49 - 52 Blocks 1-8: Cloning pBluescript II SK + DNA was digested with appropriate restriction enzymes and purified at each stage by preparative gel electrophoresis (1% agarose, TAE buffer) .

Upon cooling to room temperature, 2μl lOmM ATP, 30mM DTT and lμl T4 DNA ligase (1U) were added and the reaction incubated overnight at 16°C. TE buffer was added to a final volume of 50μl and DNA precipitated with 150μl ethanol. Pelleted DNA was dissolved in lOμl TE and lμl of the solution used to transform E. coli XL1- Blue (Bullock et al , 1987) by electroporation. Transformants were selected on LB plates containing ampicillin (50μgml _1 ) , IPTG (O.lmM) and X-gal (80μgml _1 ) . Clones were screened following DNA extraction by restriction mapping and DNA sequence analysis . The restriction enzymes used to digest pBluescript II SK + for the cloning of each of these blocks were as follows : Block pBluescript II SK + digested with 1 Kpnl , BamHl 2 Kpnl , Hindl l l 3 Hindl l l , Not! 4 Not! , Sac! 5 Spel , SacI 6 Kpnl , Spel 7 Kpnl , Pstl 8 BamHl, Pstl Construction of pSHELα,β and 7 Two (PSHEL7) or three (pSHELα,β) blocks were ligated into pBluescript II SK + in a single reaction. Each block was excised from the appropriate pBluescript II SK + -derived plasmid and purified by preparative agarose gel electrophoresis. 25ng ( ca . 0.15pmol) of each synthetic block (eg. blocks 1-3 in the case of pSHELc) and 150ng ( ca . 0.075pmol) of the appropriate pBluescript II SK + fragment were ligated in a total reaction volume of 20μl under conditions similar to those used to assemble the individual blocks. Transformants were screened by restriction analysis. The digestion schemes are illustrated in Figure 2. Final Assembly of the SHEL gene The three gene subasse blies pSHELα?,β and 7 were excised from their parent plasmids by treatment with the appropriate restriction enzymes (see cloning scheme) and purified by agarose gel electrophoresis. lOOng of pBluescript II SK + DNA linearised with BamHl and treated with calf alkaline phosphatase. This and 50ng ( ca . O.lOpmol) of each subassembly were ligated at 16°C for 1 hour using the DNA Ligation Kit (Amersham International pic) according to the supplied protocol. Transformants were selected on LB-ampicillin plates containing IPTG and X-gal, and analysed by restriction mapping. The two orientations of the SHEL gene in pBluescript were designated pSHELA and pSHELB. Expression The full length SHEL gene was excised from pSHELB with Ba Hl and purified by gel electrophoresis. 200ng of the purified fragment was ligated with lOOng pGEX-2T linearized with BamHl and treated with calf alkaline phosphatase using the DNA Ligation Kit (Amersham International pic) according to the supplied protocol. Transformants were selected on LB-ampicillin plates and screened by restriction mapping. The SHEL gene cloned into pGEX-2T was designated pSHELC. Small scale expression of pSHELC was achieved by growing 5ml cultures of E. coli DH5α containing pSHELC in LB with 50μg/ml ampicillin and 0.2% glucose at 37°C overnight. 250μl was subinoculated into 5ml 2TY and grown to an A 600 of approximately 0.8 before being induced with ImM IPTG. Cultures were grown for a further 3 hours before harvesting. For the analysis of total cell protein 1ml culture was harvested by centrifugation and resuspended in 200μl SDS-PAGE loading buffer. 20μl samples were boiled for 5 minutes before being analysed on an 8% SDS-PAGE gel. For the analysis of soluble and insoluble protein, the bacterial pellet from 3ml culture was resuspended in 500μl lysis buffer (50mM Tris-HCl pH 8, ImM EDTA, lOOmM NaCl) and lysed by the addition of lmg/ml lysozyme at 4°C for 30 minutes followed by 1% triton X-100 for 20 minutes. After the addition of 0.1 mg/ml DNase samples were sonicated. The samples were centrifuged for 15 minutes in a microfuge and the pellet resuspended in an identical volume of lysis buffer as supernatant. 20μl samples of supernatant and resuspended pellet were boiled for 5 minutes and analysed by 8% SDS- PAGE. (Figure 7) . The calculated size of the protein from SDS-PAGE was 86kD which is in close agreement with the predicted size of 90kD. The protein was over 75% soluble under the conditions used. Total amino acid content of the fusion protein was determined and the results show a high correlation with the predicted values (Figure 8) . The total level of expression was determined using SDS-PAGE and scanning densitometry and was found to be in excess of 100 mg/1. After purification of GST away from SHEL a yield of up to 70 mg/1 could theoretically be obtained. Even allowing for losses during purification this is a highly significant improvement over 4 mg/1 obtained with cDNA clones (Indik et al 1990) . Optimising codon preference has therefore increased the potential yield of tropoelastin fifteenfold. Alternatively, the SHEL gene was excised from pSHELB with both Ncol and BamHl and purified as above. lOOng of the purified fragment was ligated to 50ng pET3d, previously digested with Ncol and BamHl, using the Amersham DΝA Ligation Kit to give pSHELF. pSHELF was used to transform E. coli HMS174. After confirmation, pSHELF was extracted from HMS174 and used to transform BL21. In both cases, transformants were selected on LB- ampicillin plates and screened by restriction mapping. For pSHELF expression, 5ml LB containing 50μgml _1 ampicillin was inoculated with a single colony of E. coli BL21 (DE3) containing pSHELF and incubated overnight at 37°C with shaking. 0.25ml of this culture was used to inoculate 5ml fresh LB containing SOμgml "1 ampicillin and grown to early log phase (A 600 =0.8 approx) . IPTG was added to a final concentration of 0.4mM and growth continued for a further 3h. Total cellular protein was analysed as for pSHELC. Cell lysates were prepared by resuspension of the cell pellet in 9 volumes lysis buffer and incubation at 4°C for 30min with lmgml -1 lysozyme. PMSF was added to 0.5mM before the mixture was twice frozen in liquid nitrogen and thawed at 37°C. DΝase was added to a concentraton of 0. lmgml -1 with lOmM MgCl 2 and incubated for 20min at room temperature or until the solution was no longer viscous. Insoluble material was removed by centrifugation at 20 OOOrpm for 25min. The soluble cell lysate from 125ml culture was extracted by use of a modified version of a technique previously described for tropoelastin isolation (Sandberg et al . , 1971) . 1.5 volumes of n-propanol was added to the lysate in five aliquots over 2 hours followed by 2.5 volumes of n-butanol. All additions were performed at 4°C with constant stirring and the mixture was allowed to extract overnight . The precipitated protein was removed by centrifugation for 15min at 10 OOOrpm. The soluble alcohol fraction was frozen and dried via a vacuum pump coupled to a liquid nitrogen trap. The residue was dissolved in 3.5ml 25mM HEPES pH 8.0 and dialyzed against 1 1 of the same buffer for 2 hours, changed to fresh buffer and dialyzed overnight. The butanol precipitated protein was dissolved in an identical volume SDS-PAGE loading buffer and both fractions were analyzed by SDS- PAGE. The butanol-extracted protein containing SHEL was further purified by size fractionation using a Superose 12 column and FPLC (Pharmacia) . Protein was eluted using 25mM HEPES, pH 8.0. at a flow rate of 0.5 mlmin "1 . Protein concentration was estimated using a Bradford assay (Ausubel et al . , 1989) . Scanning densitometry of gels was performed on a Molecular Dynamics Personal Densitometer and analyzed using ImageQuant software. From SDS-PAGE the directly-expressed SHEL was calculated as being 64kDa (Figure 10 ) which- is as predicted. Total amino acid content was determined and was found to be in close agreement with predictions further confirming the nature of the overexpressed protein. The analysis (Figure 11) performed omits lysine residues . Scanning densitometry of gels was used to estimate the relative level of overexpression. SHEL was expressed at a level of approximately 17% total cell protein in the range 20-200kDa. This represents a substantial level of overexpression and confirms the value of codon manipulation for high level expression. As a result of the high levels of expression large quantities of tropoelastin were obtained which can be used for further studies. The directly expressed SHEL protein appeared stable and the rapid degradation seen previously with cDNA expression (Indik et al . , 1990) was not observed. Therefore, the purification of the free polypeptide was pursued in preference to fusion protein. A technique utilizing tropoelastin' s high solubility in short-chained alcohols has been used previously in the extraction and purification of tropoelastin from tissues (Sandberg et al . , 1971) . This method was modified for use with soluble cell lysates and found to be very effective. SHEL was selectively extracted into the alcohols while the majority of contaminating protein was precipitated and removed (Fig. 10) . The yield of SHEL after this step was high (greater than 90%) despite some loss (less than 10%) by precipitation. The resulting SHEL was of high purity as judged by SDS-PAGE after Coomassie staining (estimated by eye to be of the order greater than 80%) . A gel filtration step was used to remove the contaminating protein after which the SHEL was of sufficient purity for further characterization. Cross-linking of tropoelastin Tropoelastin obtained from PSHELF (0.3 mg/ml) was chemically cross-linked using ImM dithiobis (succinimidylpropionate) at 37°C to generate an, insoluble material with elastin-like properties. Cross-linking was demonstrated by boiling in the presence of sodium dodecyl sulphate (SDS) followed by SDS-polyacrylamide gel electrophoresis. Cross-linked material did not enter the gel under conditions designed to allow entry of uncross- linked material. Industrial Applications Cosmetic Applications Recombinant tropoelastin is similar or identical to material found in skin and other tissues and involves no animal death in order to make it . It adds to our own skin's supply of tropoelastin. Recombinant tropoelastins can be used in humans or animals. Additionally, methods such as liposome technology may be considered to deliver substances deep within the skin. Another significant area of use for tropoelastin is in minimising scar formation. The availability of large amounts of recombinant tropoelastin means that it should be possible to test whether the scarring obtained from severe cuts and burns can be minimised by regular application of tropoelastin to the affected area. Increased skin elasticity will counter the rigid effects of collagen buildup associated with scar formation, both in human and veterinary applications. Surgical and Veterinary Applications The tropoelastins and variants of this invention may be used in the repair and treatment of elastic and non- elastic tissues. They may also be used as food supplements. REFERENCES 1. Bressan, G.M., Argos, P. and Stanley, K.K. (1987) Biochemistry 26, 1497-1503. 2.
