Gelatin-replacement polypeptides

Summary

Disclosed is a gelatin-replacement polypeptide that can be suitably produced in Pichia pastoris. The polypeptide has a structure (Tblock-Gblock)n-Tblock, wherein n is an integer of from 1 to 18. Tblock is, for example, (GPP)k, with k being 6-20. Gblock comprises any one or more of the oligopeptides having the amino acid sequences GPKGEPGSPGEN, GPKGNSGEP, GPSGEPGKQGPS, and GSPGEQ, preferably Gblock has the amino acid sequence (GPKGEPGSPGENGPKGNSGEPGPSGEPGKQGPSGSPGEQ)q with q being 1 to 40.
