Protein Chemical Synthesis by Ligation of Peptide Hydrazides

Abstract

pH determines selectivity: The ligation of peptide hydrazides is a new method for protein chemical synthesis that is complementary to native chemical ligation. Peptide hydrazides may be the long-sought reagent equivalent to a “thioester synthon”, one that is stable to the conditions of native chemical ligation.
