The enzyme endoglycosylceramidase (EC 3.2.1.123) catalyzes the following chemical reaction:

oligoglycosylglucosylceramide + H2O ceramide + oligoglycosylglucose

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name is oligoglycosylglucosylceramide glycohydrolase. Other names in common use include endoglycoceramidase, EGCase, and glycosyl-N-acetyl-sphingosine 1,1-β-D-glucanohydrolase.

Structural studies

[edit]

As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 2OSW, 2OSX, 2OSY, 2OYK, 2OYL, and 2OYM.
