Accepted name: ferredoxin—NAD+ oxidoreductase (Na+-transporting)
Reaction: 2 reduced ferredoxin [iron-sulfur] cluster + NAD+ + H+ + Na+[side 1] = 2 oxidized ferredoxin [iron-sulfur] cluster + NADH + Na+[side 2]
Other name(s): Rnf complex (ambiguous); Na+-translocating ferredoxin:NAD+ oxidoreductase
Systematic name: ferredoxin:NAD+ oxidoreductase (Na+-transporting)
Comments: This iron-sulfur and flavin-containing electron transport complex, isolated from the bacterium Acetobacterium woodii, couples the energy from reduction of NAD+ by ferredoxin to pumping sodium ions out of the cell, generating a gradient across the cytoplasmic membrane.
