Enzyme Information

2.4.1.41

Polypeptide N-acetylgalactosaminyltransferase.

based on mapping to UniProt O08912

UDP-N-acetyl-alpha-D-galactosamine + polypeptide = UDP + N-acetyl-alpha- D-galactosaminyl-polypeptide.

-!- 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.
