ID 1.17.5.3 DE formate dehydrogenase-N. AN formate dehydrogenase N. AN nitrate inducible formate dehydrogenase. CA a quinone + formate + H(+) = a quinol + CO2. CC -!- Formate dehydrogenase-N oxidizes formate in the periplasm, CC transferring electrons via the menaquinone pool in the cytoplasmic CC membrane to a dissimilatory nitrate reductase (EC 1.7.5.1), which CC transfers electrons to nitrate in the cytoplasm. CC -!- The system generates proton motive force under anaerobic conditions. CC -!- Formerly EC 1.1.5.6. DR P24183, FDNG_ECOLI ; //
