alpha-xylosidase
|
|---|
| Class |

| Sysname |
alpha-D-xyloside xylohydrolase
|
|---|
| Reaction(IUBMB) |
Hydrolysis of terminal, non-reducing alpha-D-xylose residues with release of alpha-D-xylose.
|
|---|
| Comment |
The enzyme catalyses 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.
