A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 3.2.1.177

Accepted Name
Alpha-D-xyloside xylohydrolase.
Alternative Name(s)
Alpha-xylosidase.
Reaction catalysed
Hydrolysis of terminal, non-reducing alpha-D-xylose residues with release of alpha-D-xylose
Comment(s)
  • The enzyme catalyzes hydrolysis of a terminal, unsubstituted xyloside at the extreme reducing end of a xylogluco-oligosaccharide.
  • Representative alpha-xylosidases from glycoside hydrolase family 31 utilize a two-step (double-displacement) mechanism involving a covalent glycosyl-enzyme intermediate, and retain the anomeric configuration of the product.
