Sysname
UDP-N-acetyl-alpha-D-galactosamine:N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl-threonyl-[protein] 3-beta-N-acetyl-D-galactosaminyltransferase
Reaction(IUBMB)
UDP-N-acetyl-alpha-D-galactosamine + 3-O-[N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl-[protein] = UDP + 3-O-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl-[protein] [RN:
R10620 R12292 ]
Reaction(KEGG)
Substrate
UDP-N-acetyl-alpha-D-galactosamine [CPD:
C00203 ];
3-O-[N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl-[protein] [CPD:
C20723 ]
Product
UDP [CPD:
C00015 ];
3-O-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl-[protein] [CPD:
C20734 ]
Comment
The human protein is specific for UDP-N-acetyl-alpha-D-galactosamine as donor [1]. 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.
