© 2014 Elsevier Inc. All rights reserved. Serratia marcescens chitinase B (SmChiB) catalyzes the hydrolysis of β-1,4-glycosidic bond, via an unusual substrate-assisted mechanism, in which the substrate itself acts as an intramolecular nucleophile. In this paper, the catalytic mechanism of SmChiB has...
