FunFam 180: Reducing-end xylose-releasing exo-oligoxylanase Re...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Oligosaccharide reducing-end xylanase. [EC: 3.2.1.156]
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.
