General description

Glucose-6-phosphate dehydrogenase (G6P DH) has an active dimeric form, whereas its monomeric and tetrameric forms are inactive. At low NADP+ and NADPH levels and under normal conditions, the enzyme exists as equilibrium of tetramers and dimers, whereas at high NADP+ and NADPH levels the equilibrium shifts to inactive tetramers.

Application

Component of cofactor recycling systems for NADPH.

Biochem/physiol Actions

Glucose-6-phosphate dehydrogenase (G6P-DH) is involved in the pentose phosphate pathway. It is responsible for catalysing the oxidation of glucose-6-phosphate (G6P) to gluconolactone-6-phosphate, with NADP+ simultaneously accepting hydrogen to form NADPH, thereby maintaining NADPH levels in cells.

Specifications

Contaminants: <0.001% CK, <0.01% GR, HK, 6-PGDH, and PGluM each, <0.002% PGI each, <0.002% PGI
Approximately 350U/mg at +25°C with glucose-6-phosphate as the substrate.

Physical form
