ID 2.4.1.47 DE N-acylsphingosine galactosyltransferase. AN 2-hydroxyacylsphingosine 1-beta-galactosyltransferase. CA an N-acylsphing-4-enine + UDP-alpha-D-galactose = a beta-D-galactosyl- CA (1<->1')-N-acylsphing-4-enine + H(+) + UDP. CC -!- This membrane-bound, endoplasmic reticulum-located enzyme catalyzes CC the last step in the synthesis of galactocerebrosides, which are CC abundant sphingolipids of the myelin membrane of the central nervous CC system and peripheral nervous system. CC -!- It has a strong preference for ceramides that contain hydroxylated CC fatty acids. CC -!- Formerly EC 2.4.1.45. DR Q16880, CGT_HUMAN ; Q64676, CGT_MOUSE ; Q09426, CGT_RAT ; //
