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.

Enzyme kinetic parameters for rate equations are vital in metabolic network simulation, a major part of systems biology research efforts. Measurements of Michaelis-Menten kinetic parameters Km and Kcat have been performed for enzymes glucose-6-phosphate dehydrogenase (G6P DH) under crowded conditions

The removal of the N-terminal formyl group on nascent proteins by peptide deformylase (PDF) is the most prevalent protein modification in bacteria. PDF is a critical target of antibiotic development; however, its role in bacterial physiology remains a long-standing question.

High-altitude environments require that animals meet the metabolic O2 demands for locomotion and thermogenesis in O2-thin air, but the degree to which convergent metabolic changes have arisen across independent high-altitude lineages or the speed at which such changes arise is
