The enzyme endoglycosylceramidase () catalyzes the following chemical reaction:
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-ò-<small>D</small>-glucanohydrolase.
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes , , , , , and .
