Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
BRITE hierarchy
Sysname
oligoxyloglucan reducing-end cellobiohydrolase
Reaction(IUBMB)
Hydrolysis of cellobiose from the reducing end of xyloglucans consisting of a (1->4)-beta-linked glucan carrying alpha-D-xylosyl groups on O-6 of the glucose residues. To be a substrate, the first residue must be unsubstituted, the second residue may bear a xylosyl group, whether further glycosylated or not, and the third residue, which becomes the new terminus by the action of the enzyme, is preferably xylosylated, but this xylose residue must not be further substituted.
Comment
The enzyme is found in the fungus Geotrichum sp. M128. The substrate is a hemicellulose found in plant cell walls.
