ENZYME entry: EC 2.4.1.47

Accepted Name
N-acylsphingosine galactosyltransferase.
Alternative Name(s)
2-hydroxyacylsphingosine 1-beta-galactosyltransferase.
Reaction catalysed
an N-acylsphing-4-enine + UDP-alpha-D-galactose <=> a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine + H(+) + UDP
Comment(s)
  • This membrane-bound, endoplasmic reticulum-located enzyme catalyzes 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.
  • Formerly EC 2.4.1.45.
