Access to phosphoproteins and glycoproteins through semi-synthesis, Native Chemical Ligation and N→S acyl transfer.

ABSTRACT

Peptide thioesters are important tools for protein synthesis and semi-synthesis through their use in Native Chemical Ligation (NCL). NCL can be employed to assemble site-specifically modified proteins that can help elucidate the mechanisms of biomolecular processes. In this article we explore the compatibility of phosphopeptide synthesis and glycopeptide synthesis with thioester production through N→S acyl transfer.
