IntEnz Enzyme Nomenclature
EC 2.7.1.183

Names

Accepted name:
glycoprotein-mannosyl O6-kinase
Other names:
SGK196
protein O-mannose kinase
Systematic name:
ATP:O3-[N-acetyl-β-D-galactosaminyl-(1→3)-N-acetyl-β-D-glucosaminyl-(1→4)-α-D-mannosyl]-L-threonyl/L-seryl-[protein] 6-phosphotransferase

Reaction

Comments:

In humans this phosphorylated trisaccharide is attached to an L-threonine residue of α-dystroglycan, an extracellular peripheral glycoprotein that acts as a receptor for extracellular matrix proteins containing laminin-G domains, and is important for its activity.
