Function
GUX6_HUMIN Plays a central role in the recycling of plant biomass. The biological conversion of cellulose to glucose generally requires three types of hydrolytic enzymes: (1) Endoglucanases which cut internal beta-1,4-glucosidic bonds; (2) Exocellobiohydrolases that cut the dissaccharide cellobiose from the non-reducing end of the cellulose polymer chain; (3) Beta-1,4-glucosidases which hydrolyze the cellobiose and other short cello-oligosaccharides to glucose.[1]

Publication Abstract from PubMed
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.
Distortion of a cellobio-derived isofagomine highlights the potential conformational itinerary of inverting beta-glucosidases.,Varrot A, Macdonald J, Stick RV, Pell G, Gilbert HJ, Davies GJ Chem Commun (Camb). 2003 Apr 21;(8):946-7. PMID:12744312[2]
