Descrizione

General description

Phosphoglucose Isomerase is an enzyme which possesses diagnostic potential when fractionated by cellulose acetate electrophoresis. This cytosolic enzyme plays an important role during glycolysis and glucogenesis. It acts as an tumor-secreted cytokine and autocrine motility factor. It is used as neurotrophic factor, maturation factor and as serine proteinase inhibitor.[1]

Application

Isomerization of ketoses to aldoses.

Biochem/physiol Actions

Phosphoglucose isomerase (PGI) is specific for G6P (K_m = 0.7 mM) and fructose-6-phosphate (F6P).

Physical form

Suspension in 3.2 M ammonium sulfate solution, pH approximately 6

Preparation Note

Storage conditions (working solution): A solution of PGI in 20 mM Tris, pH 8.1, containing 0.2 mg BSA/ml, is stable approx. 1 week at 2 to 8 °C.

Analysis Note

Contaminants: <0.01% F6P-K, GR, 6-PGDH and PGluM, each, <0.2% β-fructosidase

Other Notes

For life science research only. Not for use in diagnostic procedures.
