Accepted name: ferric-chelate reductase (NADH)
Reaction: 2 Fe(II)-siderophore + NAD+ + H+ = 2 Fe(III)-siderophore + NADH
Other name(s): ferric chelate reductase (ambiguous); iron chelate reductase (ambiguous); NADH:Fe3+-EDTA reductase; NADH2:Fe3+ oxidoreductase; ferB (gene name); Fe(II):NAD+ oxidoreductase
Systematic name: Fe(II)-siderophore:NAD+ oxidoreductase
Comments: Contains FAD. The enzyme catalyses the reduction of bound ferric iron in a variety of iron chelators (siderophores), resulting in the release of ferrous iron. The plant enzyme is involved in the transport of iron across plant plasma membranes. The enzyme from the bacterium Paracoccus denitrificans can also reduce chromate. cf. EC, ferric-chelate reductase (NADPH) and EC, ferric-chelate reductase [NAD(P)H].
