Description
Oligosaccharide reducing-end xylanase (EC 3.2.1.156, Rex, reducing end xylose-releasing exo-oligoxylanase) is an enzyme with systematic name beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranose reducing-end xylanase. This enzyme catalyses the following chemical reaction: Hydrolysis of (1->4)-beta-D-xylose residues from the reducing end of oligosaccharides. The enzyme acts rapidly on the beta-anomer of beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranose.
