Glucose-6-phosphate dehydrogenase (G6PD or G6PDH) (EC 1.1.1.49) is a cytosolic enzyme that catalyzes the chemical reaction:D-glucose 6-phosphate + NADP+ <-> 6-phospho-D-glucono-1,5-lactone + NADPH + H+. This enzyme is in the pentose phosphate pathway, a metabolic pathway that supplies reducing energy to cells (such as erythrocytes) by maintaining the level of the co-enzyme nicotinamide adenine dinucleotide phosphate (NADPH). Glucose 6-phosphate dehydrogenase (g-6-p-dh) is a key regulatory enzyme in the first step of the pentose phosphate pathway. g-6-p-dh is a glycoprotein with a molecular mass of 128 kda (gel filtration). Applications: Glucose-6-phosphate...its/mg protein (biuret). Storage: 2-8°C.
