PEPTIDE AMIDATION PROCESS

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 cystein 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 Xl- cysteine sequence.
