Glucose-6-phosphate dehydrogenase from human erythrocytes.

Human erythrocyte glucose 6-phosphate dehydrogenase (o-glucose 6-phosphate :nicotinamide adenine dinucleotide phosphate oxidoreductase, EC 1.1.1.49) was purified by column chromatography with diethylaminoethyl cellulose, calcium phosphate gel, carboxymethyl cellulose, diethylaminoethyl Sephadex, and carboxymethyl Sephadex. A homogeneous preparation was obtained in over-all yield of about 50%. T...

Regulation of glucose-6-phosphate dehydrogenase in human erythrocytes.

Glucose-6-phosphate dehydrogenase catalyzes the initial and committed step of the pathway that is the principal source of NADPH in many cells. The intracellular rate of the enzyme in human erythrocytes was estimated from the rate at which the cells generated 14CO2 from 14C-labeled glucose in the presence of different amounts of methylene blue. This investigation differed from earlier studies in...

Protective Effect of Quercetin on Oxidative Stress in Glucose-6-Phosphate Dehydrogenase-Deficient Erythrocytes in Vitro

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...
