'''Xylosidase''' (XYL) catalyzes the hydrolysis of α- or β-glycosidic linkages. Β-XYL catalyzes the endo-hydrolysis of 1,4-β-D-glycosidic or endo-hydrolysis of 1,3-β-D-glycosidic linkage. Α-XYL catalyzes the exo-hydrolysis of 1,4-β-D-glycosidic or exo-hydrolysis of 1,3-β-D-glycosidic linkage from the non-reducing termini of xylans. XYL catalyzes the conversion of cellulose and hemicellulose xylan to xylose.
