ABSTRACT:
A composition comprising a purified collagen-like polypeptide suitable as a peptizer, said polypeptide comprising [Gly-X-Y] repeats, wherein Gly stands for glycine, X and Y represent any amino acid and n is selected such that the length of the [Gly-X-Y] repeat is at least 2.5 kDa and wherein the amino acid sequence of said polypeptide comprises more than 4 different amino acids and wherein said purified polypeptide is free of helix structure.
