Abstact

A cellobio-derived isofagomine glycosidase inhibitor (Ki approximately 400 nM) displays an unusual distorted 2,5B (boat) conformation upon binding to cellobiohydrolase Cel6A from Humicola insolens, highlighting the different conformational itineraries used by various glycosidases, with consequences for the design of therapeutic agents.
