Accepted name: glucose-6-phosphate dehydrogenase (NAD+)
Reaction: D-glucose 6-phosphate + NAD+ = 6-phospho-D-glucono-1,5-lactone + NADH + H+
Other name(s): Glc6PDH; azf (gene name); archaeal zwischenferment
Systematic name: D-glucose-6-phosphate:NAD+ 1-oxidoreductase
Comments: The enzyme catalyses a step of the pentose phosphate pathway. The enzyme from the archaeon Haloferax volcanii is specific for NAD+. cf. EC, glucose-6-phosphate dehydrogenase [NAD(P)+] and EC, glucose-6-phosphate dehydrogenase (NADP+).
