    摘要: The invention provides a process for amidating a desired peptide comprising cleaving a substrate polypeptide at a X1-cysteine sequence, wherein X1 is the amino acid at the peptide carboxyl-terminus and cysteine is the first amino acid of a palladium cleavage site comprising the sequence cysteine-X2-X3, wherein X2 is any amino acid, X3 is an amino acid selected from the group consisting of cysteine, histidine, or methionine, and wherein the carboxyl-terminus of the peptide is amidated upon cleavage at the X1-cysteine sequence.

    摘要: The invention provides a method of producing a polypeptide having a C-terminal &agr;-carboxamide group. It particularly concerns an enzymatic modification of selected substrate polypeptides which result in cleavage of the substrate polypeptide to form a product peptide with a C-terminal arginine residue having an &agr;-carboxamide group (C-terminal “Arg-NH2”). The method includes contacting an aqueous-based solution including (i) ammonia reagent and (ii) the substrate polypeptide with (iii) clostripain.
