Alpha-D-xyloside xylohydrolase.
based on mapping to UniProt P31434
Hydrolysis of terminal, non-reducing alpha-D-xylose residues with release of alpha-D-xylose.
-!- 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.
