In enzymology, a steryl-beta-glucosidase () is an enzyme that catalyzes the chemical reaction cholesteryl-beta-D-glucoside + H2O D-glucose + cholesterol Thus, the two substrates of this enzyme are cholesteryl-beta-D-glucoside and H2O, whereas its two products are D-glucose and cholesterol. This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is cholesteryl-beta-D-glucoside glucohydrolase. References EC 3.2.1 Enzymes of unknown structure
