The enzyme from Azotobacter vinelandii is a flavoprotein (FAD). It is Si-specific with respect to both NAD+ and NADP+. See EC 1.6.1.3, NAD(P)+ transhydrogenase, for enzymes whose stereo specificity is not known.
History
EC 1.6.1.1 created 1961, modified 1986, modified 2013
A flavoprotein (FAD). The main function of the enzyme is to oxidize excess of NADPH, forming NADH that supplies electrons to the respiratory chain. cf. EC 7.1.1.1, proton-translocating NAD(P)+ transhydrogenase. This entry stands for enzymes whose stereo-specificity with respect to NADPH is not known. [cf. EC 1.6.1.1, NAD(P)+ transhydrogenase (Si-specific)].
