Sysname
ATP:O3-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl/L-seryl-[protein] 6-phosphotransferase
Reaction(IUBMB)
ATP + O3-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl/L-seryl-[protein] = ADP + O3-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-(6-phospho)mannosyl]-L-threonyl/L-seryl-[protein] [RN:
R11400 R12293 ]
Reaction(KEGG)
Substrate
ATP [CPD:
C00002 ];
O3-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-mannosyl]-L-threonyl/L-seryl-[protein]
Product
ADP [CPD:
C00008 ];
O3-[N-acetyl-beta-D-galactosaminyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-D-(6-phospho)mannosyl]-L-threonyl/L-seryl-[protein]
Comment
In humans this phosphorylated trisaccharide is attached to an L-threonine residue of alpha-dystroglycan, an extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains, and is important for its activity.
