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