What is "phosphoglucosamine mutase"

n. (context biochemistry English) A phosphotransferase enzyme, alpha-D-glucosamine 1,6-phosphomutase, involved in aminosugar metabolism.

In enzymology, a phosphoglucosamine mutase is an enzyme that catalyzes the chemical reaction

alpha-D-glucosamine 1-phosphate $\rightleftharpoons$ D-glucosamine 6-phosphate

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 (phosphomutases), 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.
