Alpha-D-xyloside xylohydrolase (EC 3.2.1.177, alpha-xylosidase) is an enzyme.^{[1][2][3][4][5][6][7]} This enzyme catalyses the following chemical reaction

Hydrolysis of terminal, non-reducing alpha-D-xylose residues with release of alpha-D-xylose.

The enzyme catalyses hydrolysis of a terminal, unsubstituted xyloside at the extreme reducing end of a xylogluco-oligosaccharide.
