ID 2.4.1.92 DE (N-acetylneuraminyl)-galactosylglucosylceramide DE N-acetylgalactosaminyltransferase. AN asialo-GM2 synthase. AN beta-1,4N-aetylgalactosaminyltransferase. AN GalNAc-T. AN ganglioside GM2 synthase. AN ganglioside GM3 acetylgalactosaminyltransferase. AN GM2/GD2-synthase. AN GM2 synthase. AN UDP acetylgalactosamine-(N-acetylneuraminyl)-D-galactosyl-D- AN glucosylceramide acetylgalactosaminyltransferase. AN UDP-N-acetylgalactosamine GM3 N-acetylgalactosaminyltransferase. AN uridine diphosphoacetylgalactosamine- AN acetylneuraminylgalactosylglucosylceramide AN acetylgalactosaminyltransferase. AN uridine diphosphoacetylgalactosamine-ganglioside GM3 AN acetylgalactosaminyltransferase. AN uridine diphosphoacetylgalactosamine-hematoside AN acetylgalactosaminyltransferase. CA a ganglioside GM3 (d18:1(4E)) + UDP-N-acetyl-alpha-D-galactosamine = CA a ganglioside GM2 (d18:1(4E)) + H(+) + UDP. CC -!- Catalyzes the formation of the gangliosides (i.e. sialic-acid- CC containing glycosphingolipids) GM2, GD2 and SM2 from GM3, GD3 and CC SM3, respectively. CC -!- Asialo-GM3 and lactosylceramide are also substrates, CC but glycoproteins and oligosaccharides are not substrates. DR Q00973, B4GN1_HUMAN; Q09200, B4GN1_MOUSE; Q10468, B4GN1_RAT ; //
