Identification and characterization of a novel UDP-GalNAc:GlcAbeta-R alpha1,4-N-acetylgalactosaminyltransferase from a human sarcoma cell line.


We recently discovered a novel alpha-N-acetylgalactosaminyltransferase in fetal bovine serum (Kitagawa et al., J. Biol. Chem., 270, 22190-22195, 1995) and also in mouse mast cytoma cells (Lidholt et al., Glycoconjugate J., 14, 737-742, 1997), which catalyzed the transfer of an alpha-GalNAc residue to the linkage tetrasaccharide-serine, GlcAbeta1-3Galbeta1… (More)
