Enzyme Information

1.16.1.9
Ferric-chelate reductase (NADPH).
based on mapping to UniProt Q4V8K1
2 Fe(II)-siderophore + NADP(+) + H(+) = 2 Fe(III)-siderophore + NADPH.
-!- The enzyme, which is widespread among bacteria, catalyzes the reduction of ferric iron bound to a variety of iron chelators (siderophores), including ferric triscatecholates and ferric dicitrate, resulting in the release of ferrous iron. -!- The enzyme from the bacterium Escherichia coli has the highest efficiency with the hydrolyzed ferric enterobactin complex ferric N-(2,3-dihydroxybenzoyl)-L-serine. -!- Cf. EC 1.16.1.7 and EC 1.16.1.10.
