DE   globotriaosylceramide 3-beta-N-acetylgalactosaminyltransferase.
AN   beta3GalNAc-T1.
AN   galactosylgalactosylglucosylceramide beta-D-
AN   acetylgalactosaminyltransferase.
AN   globoside synthase.
AN   globoside synthetase.
AN   uridine diphosphoacetylgalactosamine-galactosylgalactosylglucosylceramide
AN   acetylgalactosaminyltransferase.
CA   a globoside Gb3Cer (d18:1(4E)) + UDP-N-acetyl-alpha-D-galactosamine =
CA   a globoside Gb4Cer (d18:1(4E)) + UDP + H(+).
CC   -!- Globoside is a neutral glycosphingolipid in human erythrocytes and
CC       has blood-group-P-antigen activity.
CC   -!- UDP-GalNAc is the only sugar donor that is used efficiently by the
CC       enzyme: UDP-Gal and UDP-GlcNAc result in very low enzyme activity.
CC   -!- Lactosylceramide, globoside and gangliosides GM3 and GD3 are not
CC       substrates.
