Abstract
Synthetic biopolymers can be prepared using recombinant DNA technology or chemical synthetic methods which have properties similar to naturally occuring gelatin or collagen. These materials comprise one or more polypeptides having the peptide sequence represented by the formulae I: PA1 {(Gly Pro Gln)(Gly Pro Glu).sub.4 !.sub.2 }.sub.n II: PA1 Gly Pro Glu{(Gly Pro Gln)(Gly Pro Glu).sub.4 !.sub.2 }.sub.n III: PA1 Gly Pro Xaa.sub.1 Gly Leu Xaa.sub.2 Gly Pro Arg Gly Pro Pro Gly Ala Set Gly Ala Pro Gly Pro Glu Gly Phe Gln Gly wherein Xaa.sub.1 and Xaa.sub.2 are independently the amino acids identified as Met, Ile, His, Lys, Asn, Tyr or Gln, and n is 1 to 25.
