ID 1.6.1.4 DE NAD(P)(+) transhydrogenase (ferredoxin). CA 2 reduced [2Fe-2S]-[ferredoxin] + NADH + 2 NADP(+) + H(+) = 2 oxidized CA [2Fe-2S]-[ferredoxin] + NAD(+) + 2 NADPH. 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. //
