A method for the preparation of a polypeptide of interest in authentic form by enzymatic cleavage of fusion proteins using Granzyme B protease (EC 3.4.21.79). There is also provided fusion proteins comprising a polypeptide of interest and a fusion partner, wherein the junction region between the polypeptide of interest and the fusion partner comprises a Granzyme B protease cleavage site adjacent to the polypeptide of interest, and a human Granzyme B protease variant wherein the Cystein residue no. 228 (chymotrypsinogen numbering) is mutated to Phenylalanine.
一种通过使用 Granzyme B 蛋白酶(EC 3.4.21.79)对融合蛋白进行酶解来制备真品多肽的方法。还提供了由感兴趣的多肽和融合伙伴组成的融合蛋白,其中感兴趣的多肽和融合伙伴之间的连接区包括与感兴趣的多肽相邻的 Granzyme B 蛋白酶裂解位点,以及人 Granzyme B 蛋白酶变体,其中胱氨酸残基 228 号(糜蛋白酶原编号)突变为苯丙氨酸。
