N-acetyl-β-glucosaminyl-glycoprotein 4-β-N-acetylgalactosaminyltransferase

The enzyme from human can transfer N-acetyl-D-galactosamine (GalNAc) to N-glycan and O-glycan substrates that have N-acetyl-D-glucosamine (GlcNAc) but not D-glucuronic acid (GlcUA) at their non-reducing end. The N-acetyl-β-D-glucosaminyl group is normally on a core oligosaccharide although benzyl glycosides have been used in enzyme-characterization experiments. Some glycohormones, e.g. lutropin and thyrotropin contain the N-glycan structure containing the N-acetyl-β-D-galactosaminyl-(1→4)-N-acetyl-β-D-glucosaminyl group.
