Galactosylceramidase
Galactosylceramidase,, is an enzyme that removes galactose from ceramide derivatives by catalysing the hydrolysis of galactose ester bonds of galactosylceramide, galactosylsphingosine, lactosylceramide, and monogalactosyldiglyceride.
It is a lysosomal protein, encoded in humans by the GALC gene. Mutations in this gene have been associated with Krabbe disease, also known as galactosylceramide lipidosis.
