ID 1.17.1.11 DE formate dehydrogenase (NAD(+), ferredoxin). AN electron-bifurcating formate dehydrogenase. CA 2 formate + NAD(+) + 2 oxidized [2Fe-2S]-[ferredoxin] = 2 CO2 + H(+) + CA NADH + 2 reduced [2Fe-2S]-[ferredoxin]. CC -!- The enzyme complex, isolated from the bacterium Gottschalkia CC acidurici, couples the reduction of NAD(+) and the reduction of CC ferredoxin with formate via flavin-based electron bifurcation. CC -!- Formerly EC 1.2.1.93. //
