CC -!- FUNCTION: Acts as a transcriptional regulator. Probably redox-
CC responsive. The apo- but not holo-form probably binds DNA.
CC {ECO:0000256|HAMAP-Rule:MF_01479}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01479};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. Following nitrosylation of
CC the [4Fe-4S] cluster binds 1 [4Fe-8(NO)] cluster per subunit.
CC {ECO:0000256|HAMAP-Rule:MF_01479};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|HAMAP-Rule:MF_01479}.
CC -!- PTM: The Fe-S cluster can be nitrosylated by nitric oxide (NO).
CC {ECO:0000256|HAMAP-Rule:MF_01479}.
CC -!- PTM: Upon Fe-S cluster removal intramolecular disulfide bonds are
CC formed. {ECO:0000256|HAMAP-Rule:MF_01479}.
CC -!- SIMILARITY: Belongs to the WhiB family. {ECO:0000256|ARBA:ARBA00006597,
CC ECO:0000256|HAMAP-Rule:MF_01479}.
