EC 1.18.1.8 Details

show Brenda entry

EC number

1.18.1.8

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)

Comment

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.
