Sysname
UDP-alpha-D-galactose:N-acylsphingosine beta-D-galactosyltransferase (configuration-inverting)
Reaction(IUBMB)
UDP-alpha-D-galactose + a ceramide = UDP + a beta-D-galactosylceramide [RN:
R01500 R06277 ]
Reaction(KEGG)
Substrate
Product
UDP [CPD:
C00015 ];
beta-D-galactosylceramide
Comment
This membrane-bound, endoplasmic reticulum-located enzyme catalyses the last step in the synthesis of galactocerebrosides, which are abundant sphingolipids of the myelin membrane of the central nervous system and peripheral nervous system. It has a strong preference for ceramides that contain hydroxylated fatty acids.
