CC   -!- FUNCTION: Acts as a global negative controlling element, employing
CC       Fe(2+) as a cofactor to bind the operator of the repressed genes.
CC       Regulates the expression of several outer-membrane proteins including
CC       the iron transport operon (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Fur family. {ECO:0000305}.
