Adrenodoxin reductase transfers electrons from NADPH to adrenodoxin, which subsequently donates them to the cytochrome P450 forms. H(+) + NADP(+) + 2 reduced [adrenodoxin] = NADPH + 2 oxidized [adrenodoxin] Lethality in aerobic growth conditions and also during fermentation. Present with 1600 molecules/cell in log phase SD medium. Belongs to the ferredoxin--NADP reductase type 1 family.
