In enzymology, a glucosylceramidase (EC 3.2.1.45) is an enzyme that catalyzes the chemical reaction

Contents

D-glucosyl-N-acylsphingosine + H2O D-glucose + N-acylsphingosine

Thus, the two substrates of this enzyme are D-glucosyl-N-acylsphingosine and H2O, whereas its two products are D-glucose and N-acylsphingosine.

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 D-glucosyl-N-acylsphingosine glucohydrolase. Other names in common use include:

This enzyme participates in sphingolipid metabolism and degradation of glycan structures.

β-Glucocerebrosidase is an enzyme with glucosylceramidase activity that cleaves by hydrolysis the β-glycosidic linkage of the chemical glucocerebroside, an intermediate in glycolipid metabolism that is abundant in cell membranes. It is localized in the lysosome, where it remains associated with the lysosomal membrane. β-Glucocerebrosidase is 497 amino acids in length and has a molecular mass of 59,700 Da.

<span class="mw-page-title-main">Cyclophellitol</span> Chemical compound

Cyclophellitol is a potent irreversible inhibitor of beta-glucosidases. It is a cyclitol mimic of beta-glucose with an epoxide group in place of the acetal group found in glucosides. When recognized, cyclophellitol undergoes an acid-catalyzed ring-opening addition reaction with the catalytic nucleophile of a retaining glycoside hydrolase. The resulting ester linkage cannot be hydrolyzed by the normal catalytic machinery of the enzyme, resulting in irreversible inhibition.
