ID 1.6.1.4 DE NAD(P)(+) transhydrogenase (ferredoxin). CA H(+) + NADH + 2 NADP(+) + 2 reduced [2Fe-2S]-[ferredoxin] = NAD(+) + CA 2 NADPH + 2 oxidized [2Fe-2S]-[ferredoxin]. CC -!- The iron-sulfur flavoprotein complex, isolated from the bacterium CC Clostridium kluyveri, couples the exergonic reduction of NADP(+) with CC reduced ferredoxin and the endergonic reduction of NADP(+) with NADH. //
