IUBMB Enzyme Nomenclature


Accepted name: ferredoxin—NAD(P)+ reductase (naphthalene dioxygenase ferredoxin-specific)

Reaction: 2 reduced [2Fe-2S] ferredoxin + NAD(P)+ + H+ = 2 oxidized [2Fe-2S] ferredoxin + NAD(P)H

Glossary: ferredoxin

Other name(s): NADH-ferredoxin(NAP) reductase

Systematic name: ferredoxin:NAD(P)+ oxidoreductase

Comments: The enzyme from the aerobic bacterium Ralstonia sp. U2 donates electrons to both EC, naphthalene 1,2-dioxygenase and EC, salicylate 5-hydroxylase [1]. The enzyme from Pseudomonas NCIB 9816 is specific for the ferredoxin associated with naphthalene dioxygenase; it contains FAD and a [2Fe-2S] cluster.
