IntEnz Enzyme Nomenclature


Accepted name:
glucose-6-phosphate dehydrogenase [NAD(P)+]
Other names:
Systematic name:
D-glucose-6-phosphate:NAD(P)+ 1-oxidoreductase



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, glucose-6-phosphate dehydrogenase (NADP+) and EC, glucose-6-phosphate dehydrogenase (NAD+).
