CC -!- FUNCTION: Plays an essential role in iron intracellular trafficking to
CC iron cofactor biogenesis systems including iron-sulfur cluster (Fe-S)
CC or heme assembly (PubMed:21744456, PubMed:25826316). Promotes the
CC biosynthesis of iron-sulfur clusters by delivering Fe to the complex
CC composed of the cysteine desulfurase SufS and the zinc-dependent
CC sulfurtransferase SufU (PubMed:27382962). Also plays a critical role in
CC coproporphyrin-dependent heme b biogenesis and thus provides an
CC essential function for the bacterial global metabolism.

CC Evidence={ECO:0000269|PubMed:20087498, ECO:0000269|PubMed:21744456};
CC Note=Binds 1.0 Fe(2+) (PubMed:20087498) to 1.5 to 3.2 Fe(2+) per
CC monomer (PubMed:21744456). {ECO:0000269|PubMed:20087498,
CC ECO:0000269|PubMed:21744456};
CC -!- SUBUNIT: Homodimer, upon Fe(2+) binding (PubMed:20087498). Interacts
CC with the SufS/SufU complex (PubMed:27382962). Interacts with CpfC
CC (PubMed:25826316). {ECO:0000269|PubMed:20087498,
CC ECO:0000269|PubMed:25826316, ECO:0000269|PubMed:27382962}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:21744456}.
CC -!- DISRUPTION PHENOTYPE: Reduced growth in rich medium, unable to grow in
CC minimal medium. Reduced activity of Fe-S-dependent aconitase (citB).
CC Reactive oxygen species are drastically reduced. No bacillibactin (BB),
CC an endogenous siderophore, produced. 20% higher intracellular iron
CC concentrations. {ECO:0000269|PubMed:21744456}.
