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