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. {ECO:0000256|ARBA:ARBA00037693}.
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
