Enzyme Commission Primary Name: glycosylceramidase

Enzyme Commission Synonyms: phlorizin hydrolase, phloretin-glucosidase, glycosyl ceramide glycosylhydrolase, cerebrosidase, phloridzin β-glucosidase, lactase-phlorizin hydrolase, phloridzin glucosidase

Taxonomic Range: Metazoa

Enzyme Commission Summary:
Broad specificity [cf. EC (glucosylceramidase) and EC (galactosylceramidase)]. Also hydrolyses phlorizin to phloretin and glucose. The intestinal enzyme is a complex that also catalyses the reaction of EC lactase.
