Efficient chemoenzymatic synthesis of sialyl Tn-antigens and derivatives

Chem Commun (Camb). 2011 Aug 14;47(30):8691-3. doi: 10.1039/c1cc12732b. Epub 2011 Jul 1.

Abstract

An N-terminal and C-terminal truncated recombinant α2-6-sialyltransferase cloned from Photobacterium sp. JH-ISH-224, Psp2,6ST(15-501)-His(6), was shown to be an efficient catalyst for one-pot three-enzyme synthesis of sialyl Tn (STn) antigens and derivatives containing natural and non-natural sialic acid forms.
