Glycosynthase‐Mediated Assembly of Xylanase Substrates and Inhibitors

Abstract

An exo-β-xylosidase mutant with glycosynthase activity was created to aid in the synthesis of xylanase substrates and inhibitors. Simple monosaccharides were easily elaborated into di-, tri- and tetrasaccharides by using this enzyme. Some products proved to be surprisingly potent inhibitors of xylanases from glycoside hydrolase families 10 and 11.
