IUBMB Enzyme Nomenclature

EC 1.16.1.10

Accepted name: ferric-chelate reductase [NAD(P)H]

Reaction: 2 Fe(II)-siderophore + NAD(P)+ + H+ = 2 Fe(III)-siderophore + NAD(P)H

Other name(s): ferric reductase (ambiguous)

Systematic name: Fe(II)-siderophore:NAD(P)+ oxidoreductase

Comments: A flavoprotein. The enzyme catalyses the reduction of bound ferric iron in a variety of iron chelators (siderophores), resulting in the release of ferrous iron. The enzyme from the hyperthermophilic archaeon Archaeoglobus fulgidus is not active with uncomplexed Fe(III). cf. EC 1.16.1.7, ferric-chelate reductase (NADH) and EC 1.16.1.9, ferric-chelate reductase (NADPH).
