KEGG   ENZYME: 3.2.1.156
Entry
EC 3.2.1.156                Enzyme                                 
Name
oligosaccharide reducing-end xylanase;
Rex;
reducing end xylose-releasing exo-oligoxylanase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
beta-D-xylopyranosyl-(1->4)-beta-D-xylopyranose reducing-end xylanase
Reaction(IUBMB)
Hydrolysis of (1->4)-beta-D-xylose residues from the reducing end of oligosaccharides
Comment
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.
