In enzymology, a phosphoglucosamine mutase (EC 5.4.2.10) is an enzyme that catalyzes the chemical reaction In enzymology, a phosphoglucosamine mutase (EC 5.4.2.10) is an enzyme that catalyzes the chemical reaction Hence, this enzyme has one substrate, alpha-D-glucosamine 1-phosphate, and one product, D-glucosamine 6-phosphate. This enzyme belongs to the family of isomerases, specifically the phosphotransferases (a-D-phosphohexomutases), which transfer phosphate groups within a molecule. The systematic name of this enzyme class is alpha-D-glucosamine 1,6-phosphomutase. This enzyme participates in aminosugars metabolism.
