General description
Research area: Cell Signaling
Glucose-6-phosphate dehydrogenase (G6PD) is found in the cytoplasm of all cells. The G6PD enzyme is encoded by the Gd gene, located on the long arm of the X chromosome.Glucose-6-phosphate Dehydrogenase (G6PD) from Leuconostoc mesenteroides catalyzes the oxidation of glucose 6-phosphate in the presence of nicotinamide adenine dinucleotide (NAD+) or nicotinamide adenine dinucleotide phosphate (NADP+). It corresponds to a molecular weight of 54 kDa and exists as a homodimer.

Application
Glucose-6-phosphate Dehydrogenase from Leuconostoc mesenteroides has been used:
- as a component of reaction mixture for assaying mannose- and glucose-6-phosphate activity
- as a component of reaction mixture in the nevirapine inhibition studies in human hepatic microsomes
- in the glucose-phosphorylating activity of chloroplast extracts
- as a model to test the effect of seed protein fractions on enzyme protection during dehydration.
- in assays for nicotinamide adenine dinucleotide and tissue pyridine nucleotides.
Biochem/physiol Actions
Glucose-6-phosphate dehydrogenase (G6PD) is a housekeeping enzyme that protects cells from damage caused by reactive oxygen species by supplying substrates that help prevent oxidative harm. G6PD from Leuconostoc mesenteroides catalyzes the oxidation of glucose 6-phosphate in the presence of nicotinamide adenine dinucleotide (NAD+) or nicotinamide adenine dinucleotide phosphate (NADP+) as the first step in the pentose phosphate pathway. Lysine 21 in the Glucose-6-phosphate Dehydrogenase (G6PD) is crucial for binding NAD+. G6PD uses NAD+ or NADP+ based on the catabolic or anabolic metabolic pathway.G6PD deficiency can lead to acute hemolysis, neonatal jaundice, or severe chronic non-spherocytic hemolytic anemia.
Glucose-6-phosphate dehydrogenase (G6PD) catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.
Physical form
Suspension in 2.7 M (NH4)2SO4 solution containing 42 mM Tris and 0.8 mM MgCl2
Other Notes
One unit will oxidize 1.0 μmole of D-glucose 6-phosphate to 6-phospho-D-gluconate per min in the presence of NAD at pH 7.8 at 30 °C.
