ENZYME entry: EC 2.4.1.41

Accepted Name
polypeptide N-acetylgalactosaminyltransferase.
Alternative Name(s)
protein-UDP acetylgalactosaminyltransferase.
Reaction catalysed
  • L-seryl-[protein] + UDP-N-acetyl-alpha-D-galactosamine <=> 3-O-[N-acetyl-alpha-D-galactosaminyl]-L-seryl-[protein] + H(+) + UDP
  • L-threonyl-[protein] + UDP-N-acetyl-alpha-D-galactosamine <=> 3-O-[N-acetyl-alpha-D-galactosaminyl]-L-threonyl-[protein] + H(+) + UDP
Comment(s)
The glycosyl residue is transferred to threonine or serine hydroxy groups on the polypeptide core of submaxillary mucin, kappa-casein, apofetuin and some other acceptors of high molecular mass.
