EC 1.1.1.363

Accepted name: glucose-6-phosphate dehydrogenase [NAD(P)+]

Reaction: D-glucose 6-phosphate + NAD(P)+ = 6-phospho-D-glucono-1,5-lactone + NAD(P)H + H+

Other name(s): G6PDH; G6PD; Glc6PD

Systematic name: D-glucose-6-phosphate:NAD(P)+ 1-oxidoreductase

Comments: The enzyme catalyses a step of the pentose phosphate pathway. The enzyme from the Gram-positive bacterium Leuconostoc mesenteroides prefers NADP+ while the enzyme from the Gram-negative bacterium Gluconacetobacter xylinus prefers NAD+. cf. EC 1.1.1.49, glucose-6-phosphate dehydrogenase (NADP+) and EC 1.1.1.388, glucose-6-phosphate dehydrogenase (NAD+).
