ID   7.1.1.11
DE   ferredoxin--NAD(+) oxidoreductase (H(+)-transporting).
AN   Rnf complex.
CA   3 H(+)(in) + NAD(+) + 2 reduced [2Fe-2S]-[ferredoxin] = 2 H(+)(out) +
CA   NADH + 2 oxidized [2Fe-2S]-[ferredoxin].
CC   -!- This iron-sulfur and flavin-containing electron transport complex,
CC       isolated from some anaerobic bacteria, couples the energy from
CC       reduction of NAD(+) by ferredoxin to pumping protons out of the cell,
CC       generating a proton motive force across the cytoplasmic membrane.
CC   -!- Most similar complexes pump sodium ions rather than protons (cf.
CC       EC 7.2.1.2).
