What is "phosphoglucomutase"

n. (context enzyme English) Any enzyme that catalyzes the interconversion of isomers of glucose phosphates

Phosphoglucomutase is an enzyme that transfers a phosphate group on an α-D- glucose monomer from the 1' to the 6' position in the forward direction or the 6' to the 1' position in the reverse direction.

More precisely, it facilitates the interconversion of glucose 1-phosphate and glucose 6-phosphate.

In enzymology, a phosphoglucomutase (glucose-cofactor) is an enzyme that catalyzes the chemical reaction

alpha-D-glucose 1-phosphate $\rightleftharpoons$ 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.
