Identification
NameAlkaline ceramidase YPC1
SynonymsNot Available
Gene NameYPC1
Enzyme Class
Biological Properties
General FunctionInvolved in hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides
Specific FunctionHydrolyzes phytoceramide and also dihydroceramide into phytosphingosine or dihydrosphingosine. Prefers phytoceramide. Has also reverse hydrolysis activity, catalyzing synthesis of phytoceramide and dihydroceramide from palmitic acid and phytosphingosine or dihydrosphingosine. Is not responsible for the breakdown of unsaturated ceramide
Cellular LocationEndoplasmic reticulum membrane; Multi-pass membrane protein. Golgi apparatus membrane; Multi-pass membrane protein
