What is "beta-phosphoglucomutase"

In enzymology, a beta-phosphoglucomutase is an enzyme that catalyzes the chemical reaction

beta-D-glucose 1-phosphate $\rightleftharpoons$ beta-D-glucose 6-phosphate

Hence, this enzyme has one substrate, beta-D-glucose 1-phosphate, and one product, beta-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 beta-D-glucose 1,6-phosphomutase. This enzyme participates in starch and sucrose metabolism.
