ENZYME entry: EC 2.4.1.313

Accepted Name
protein O-mannose beta-1,3-N-acetylgalactosaminyltransferase
Reaction catalysed
3-O-(N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl)-L-threonyl-[protein] + UDP-N-acetyl-alpha-D-galactosamine = 3-O-[beta-D-GalNAc-(1->3)-beta-D-GlcNAc-(1->4)-alpha-D-Man]-L-Thr-[protein] + UDP + H(+)
Comment(s)
  • The human protein is specific for UDP-N-acetyl-alpha-D-galactosamine as donor.
  • The enzyme is involved in the formation of a phosphorylated trisaccharide on a threonine residue of alpha-dystroglycan, an extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains.
