Xylosidase

spinqualitylabelsall models Structure ofα-xylosidase family 31 complex with pentaerythritol propoxylate, sulfate, Ni+2 (small green) and Cl- (large green) ions (PDB entry 2xvl) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Xylosidase (XYL) catalyzes the hydrolysis of α- or β-glycosidic linkages. 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. β-XYL catalyzes the endo-hydrolysis of 1,4-β-D-glycosidic or endo-hydrolysis of 1,3-β-D-glycosidic linkage. α-XYL family 31 catalyzes the hydrolysis of α-xylosyl from isoprimeverose. β-XYL family 3 catalyzes the endo-hydrolysis of 1,4-β-D-glycosidic or endo-hydrolysis of 1,3-β-D-glycosidic linkage. β-XYL family 43 and β-XYL family 52 degrade xylooligosaccharides, . β-XYL family 120 degrades xylobiose and xylotriose. β-XYL/glucosidase bifunctional enzyme active on beta-xylosides and beta-glucosides. Structural highlights The active site of α-xylosidase contains the xyloglucan and nucleophilic water. Water molecules are shown as red spheres.
