the common identity of human acidic beta-d-glucosidase ( beta-d-glucoside glucohydrolase , ec 3.2.1.21 ) and beta-d-xylosidase ( 1,4-beta-d-xylan xylohydrolase , ec 3.2.1.37 ) as one enzyme and that of acidic beta-d-galactosidase ( beta-d-galactoside galactohydrolase , ec 3.2.1.23 ) , beta-d-fucosidase ( no allotted ec number ) and alpha-l-arabinosidase ( alpha-l-arabinofuranoside arabinohydrolase , ec 3.2.1.55 ) as another enzyme is indicated by similar binding patterns of glycosidase activities of each enzyme to various lectins . by similar ratios between their intra- and extracellular levels in normal and i-cell fibroblasts and by their deficiencies in liver tissues from patients with gaucher disease and gm1 gangliosidosis , respectively .
