show Brenda entry

EC number

1.18.1.3

Accepted name

ferredoxin—NAD⁺ reductase

Reaction

(1) 2 reduced [2Fe-2S] ferredoxin + NAD⁺ + H⁺ = 2 oxidized [2Fe-2S] ferredoxin + NADH;;(2) reduced 2[4Fe-4S] ferredoxin + NAD⁺ + H⁺ = oxidized 2[4Fe-4S] ferredoxin + NADH

Other name(s)

ferredoxin-nicotinamide adenine dinucleotide reductase, ferredoxin reductase (ambiguous), NAD⁺-ferredoxin reductase, NADH-ferredoxin oxidoreductase, reductase, reduced nicotinamide adenine dinucleotide-ferredoxin, ferredoxin-NAD⁺ reductase, NADH-ferredoxin reductase, NADH₂-ferredoxin oxidoreductase, NADH flavodoxin oxidoreductase, NADH-ferredoxin NAP reductase (component of naphthalene dioxygenase multicomponent enzyme system), ferredoxin-linked NAD⁺ reductase, NADH-ferredoxin TOL reductase (component of toluene dioxygenase), ferredoxin—NAD reductase

Systematic name

ferredoxin:NAD⁺ oxidoreductase

CAS registry number

39369-37-4

Comment

Contains FAD. Reaction (1) is written for a [2Fe-2S] ferredoxin, which is characteristic of some mono- and dioxygenase systems. The alternative reaction (2) is written for a 2[4Fe-4S] ferredoxin, which transfers two electrons, and occurs in metabolism of anaerobic bacteria.

History

created 1976 as EC 1.6.7.3, transferred 1978 to EC 1.18.1.3, modified 2011
