Phosphoglucomutase (PGM), a conserved enzyme, is abundantly found in animals, plants, and microorganisms. It is distributed in almost all tissues.

Phosphoglycomutase has been used:

• to study glycogenesis and phosphoglycomutase deficiency in humans
• in phosphoglucomutase assays to study metabolic regulation
• for assay A to assay enzymes closely linked to glycogen metabolism in transformed BL21(DE3)C43 cells
• in sucrose synthase (SuSy) andADPglucose pyrophosphorylase (AGPase) assays(3)
• in enzyme activity assay for coupling the reduction of nicotinamide adenine dinucleotide phosphate (NADP⁺)to determine glucose-1-phosphate from sucrose and inorganic phosphate (Pi)

Phosphoglucomutase(PGM) enzyme plays a vital role in glycolysis and gluconeogenesis. It is involved in glycogen and trehalose metabolism in insects. PGM participates in the development of plants and some microorganisms. It is essential for proteins, lipids, and nucleic acid metabolism and is crucial for the development of plants because glucose-6-phosphate is a crucial central metabolite. PGM catalyzes the interconversion of glucose-6-phosphate (G-6-P)and glucose-1-phosphate (G-1-P).

One unit will convert 1.0 μmole of α-D-glucose 1-phosphate to α-D-glucose 6-phosphate per min at pH 7.4 at 30 °C.
