Enzyme Information

2.4.1.41

Polypeptide N-acetylgalactosaminyltransferase.

based on mapping to UniProt Q10471

(1) UDP-N-acetyl-alpha-D-galactosamine + [protein]-L-serine = UDP + [protein]-3-O-(N-acetyl-alpha-D-galactosaminyl)-L-serine. (2) UDP-N-acetyl-alpha-D-galactosamine + [protein]-L-threonine = UDP + [protein]-3-O-(N-acetyl-alpha-D-galactosaminyl)-L-threonine.

-!- 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.
