Description
Beta-glucosidase is a glucosidase enzyme located in on the brush border of the small intestine that acts upon β1->4 bonds linking two glucose or glucose-substituted molecules (i.e., the disaccharide cellobiose). It is one of the cellulases, enzymes involved in the decomposition of cellulose and related polysaccharides; more specifically, an exocellulase with specificity for a variety of beta-D-glycoside substrates. It catalyzes the hydrolysis of terminal non-reducing residues in beta-D-glucosides with release of glucose.
Abbr
β-Glucosidase, Recombinant
Applications
β-Glucosidase is a lysosomal enzyme which breaks β1->4 bonds that link oligosaccharides. β-Glucosidase is used to study Gaucher disease and potential treatments such as enzyme replacement therapy. β-Glucocerebrosidase is an enzyme with glucosylceramidase activity (EC 3.2.1.45) that is needed to cleave, by hydrolysis, the beta-glucosidic linkage of the chemical glucocerebroside, an intermediate in glycolipid metabolism. It is localized in the lysosome and has a molecular weight of 59700 Daltons.
