Abstract
Collagen-like polymers having repetitive triads are produced having reduced proline content, where glycine is the initial amino acid and the subsequent amino acids are varied, while retaining at least a minimum percentage of prolines. The resulting polymers have collagen-like properties, but are capable of being produced in unicellular microorganisms at high molecular weights and in high efficiency. The polymers while retaining collagen-like characteristics, include various novel sequences which impart new characteristics, finding wide use in photographic, medical, structural and fiber applications.
