Phosphoglucomutase (glucose-cofactor)
- Phosphoglucomutase (glucose-cofactor)
In enzymology, a phosphoglucomutase (glucose-cofactor) (EC number|5.4.2.5) is an enzyme that catalyzes the chemical reaction
:alpha-D-glucose 1-phosphate D-glucose 6-phosphate
Hence, this enzyme has one substrate, alpha-D-glucose 1-phosphate, and one product, D-glucose 6-phosphate.
This enzyme belongs to the family of isomerases, specifically the phosphotransferases (phosphomutases), which transfer phosphate groups within a molecule. The systematic name of this enzyme class is alpha-D-glucose 1,6-phosphomutase (glucose-cofactor). Other names in common use include glucose phosphomutase, and glucose-1-phosphate phosphotransferase. This enzyme has at least one effector, D-Glucose.
