spinqualitylabelsall models Structure of α-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 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[1]. 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[2]. Structural highlights The [3]. Water molecules are shown as red spheres. . 3D Structures of xylosidase Xylosidase 3D structures
