General description
Application
Phosphoglucose Isomerase from baker′s yeast (S. cerevisiae) has been used:
- to convert fructose-6-phosphate to glucose-6-phosphate during the enzymatic measurement of serum mannose levels.[3]
- as one of the enzymes in the series of four enzyme-coupled reactions to measure phosphomannomutase (PMM) activity.[4]
- to convert fructose to glucose while evaluating fructose content in kudzu roots.[5]
Biochem/physiol Actions
Phosphoglucose Isomerase(PGI) is an enzyme crucial for the interconversion of D-glucose 6-phosphate and D-fructose 6-phosphate. PGI is responsible for the second step of glycolysis and is involved in glucogenesis and pentose phosphate pathway (PPP).[6] It is highly conserved in bacteria and eukaryotes. PGI plays a vital role in the survival of A. fumigatus and demonstrates diverse functions that encompass development, biosynthesis of cell wall glucan, and virulence.[7]Phosphoglucose Isomerase functions as an isomerase, neuroleukin, autocrine motility factor, and a differentiation and maturation mediator.[6]
Unit Definition
One unit will convert 1.0 μmole of D-fructose 6-phosphate to D-glucose 6-phosphate per min at pH 7.4 at 25 °C.
Physical form
Crystalline suspension in 2.6 M (NH4)2SO4 containing 0.1 mM magnesium acetate, pH 7.0
