Semisynthesis of a homogeneous glycoprotein enzyme: ribonuclease C: part 1

Angew Chem Int Ed Engl. 2009;48(11):1936-40. doi: 10.1002/anie.200804734.

Abstract

Seven in one blow: The efficient formation of mixed disulfides on the thiol-rich fusion protein A followed by subsequent intein cleavage gave the fragment B with all seven cysteines protected against oxidation. The native chemical ligation of B with synthetic glycopeptide thioesters provides glycoproteins.
