Oligosaccharide reducing-end xylanase.
based on mapping to UniProt Q9KB30
Hydrolysis of (1->4)-beta-D-xylose residues from the reducing end of oligosaccharides.
-!- The enzyme, originally isolated from the bacterium Bacillus halodurans C-125, releases the xylose unit at the reducing end of oligosaccharides ending with the structure beta-D-xylopyranosyl- (1->4)-beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranose, leaving the new reducing end in the alpha configuration. -!- It is specific for the beta anomers of xylooligosaccharides whose degree of polymerization is equal to or greater than 3. -!- The penultimate residue must be beta-D-xylopyranose, but replacing either of the flanking residues with glucose merely slows the rate greatly.
