CC   -!- FUNCTION: Regulation of iron dicitrate transport. In the absence of
CC       citrate FecR inactivates fecI. FecR is probably a sensor that
CC       recognizes iron dicitrate in the periplasm.
CC   -!- SUBCELLULAR LOCATION: Periplasm.
CC   -!- INDUCTION: Induced by hydroxyurea. {ECO:0000269|PubMed:20005847}.
