Cytosolic beta-glucosidase, also known as cytosolic beta-glucosidase-like protein 1, is a beta-glucosidase (EC3.2.1.21) enzyme that in humans is encoded by the GBA3gene.[3][4]
Cytosolic beta-glucosidase is a predominantly liver enzyme that efficiently hydrolyzes beta-D-glucoside and beta-D-galactoside, but not any known physiologic beta-glycoside, suggesting that it may be involved in detoxification of plant glycosides.[4] GBA3 also has significant neutral glycosylceramidase activity (EC3.2.1.62), suggesting that it may be involved in a non-lysosomal catabolic pathway of glucosylceramide metabolism.[5]
