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-Glucanase 1, Recombinant
Applications
β-Glucanase is used to study cell wall modifications and for carbohydrate hydrolysis. It has been used to supplement barley-based diets for poultry and to study the reopening signal conduits and release of dormancy in the Populusspecies.
