Irreversible site-specific hydrazinolysis of proteins by use of sortase

Angew Chem Int Ed Engl. 2014 Feb 17;53(8):2198-202. doi: 10.1002/anie.201310010. Epub 2014 Jan 27.

Abstract

Sortase-mediated hydrazinolysis of proteins with hydrazine or its derivatives was developed for the production of recombinant protein hydrazides. This process provides an alternative approach for protein semisynthesis through the use of recombinant protein hydrazides as thioester surrogates. It also provides an alternative method for C-terminal modification of proteins with functional units as well as for the preparation of C-to-C fusion proteins.

Keywords: hydrazones; hydrolysis; ligation; protein modification; proteins.
