ID   2.4.1.41
DE   Polypeptide N-acetylgalactosaminyltransferase.
AN   Protein-UDP acetylgalactosaminyltransferase.
CA   (1) UDP-N-acetyl-alpha-D-galactosamine + [protein]-L-serine = UDP +
CA   [protein]-3-O-(N-acetyl-alpha-D-galactosaminyl)-L-serine.
CA   (2) UDP-N-acetyl-alpha-D-galactosamine + [protein]-L-threonine = UDP +
CA   [protein]-3-O-(N-acetyl-alpha-D-galactosaminyl)-L-threonine.
CF   Ca(2+); Mn(2+).
CC   -!- The glycosyl residue is transferred to threonine or serine hydroxy
CC       groups on the polypeptide core of submaxillary mucin, kappa-casein,
CC       apofetuin and some other acceptors of high molecular mass.
