In enzymology, a galactosylceramide sulfotransferase (EC 2.8.2.11) is an enzyme that catalyzes the chemical reaction
- 3'-phosphoadenylyl sulfate + a galactosylceramide adenosine 3',5'-bisphosphate + a galactosylceramidesulfate
Thus, its two substrates are 3'-phosphoadenylyl sulfate and galactosylceramide, and its two products are adenosine 3',5'-bisphosphate and galactosylceramidesulfate.
It belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:galactosylceramide 3'-sulfotransferase. Other names in common use include GSase, 3'-phosphoadenosine-5'-phosphosulfate-cerebroside sulfotransferase, galactocerebroside sulfotransferase, galactolipid sulfotransferase, glycolipid sulfotransferase, and glycosphingolipid sulfotransferase. This enzyme participates in sphingolipid metabolism.
