|Oligosaccharide reducing-end xylanase.
|Reducing end xylose-releasing exo-oligoxylanase.|
|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
