Abstract:
1. A process for producing a polypeptide, which comprises: reacting a peptide component (A) represented by formula (1) below with a peptide component (B) represented by formula (2) below and optionally a compound (C) represented by formula (3) below, to obtain said polypeptide: (1) X-(Pro-Y-Gly) (2) X-(Z) (3) H further wherein the ratio of the peptide component (A) relative to the peptide component (B) [the former (A)/the latter (B)] is 100/0 to 30/70 (mol %); provided that in the case where X represents the group HOOC—(CH in the case where X represents H in the formula (1) and/or (2), the reaction is conducted without compound (C).
