Identifier, protein and gene names [?]

Protein name
RecName: Full=Transcriptional regulator WhiB;
Gene name

Comments [?]

Function Acts as a transcriptional regulator. Probably redox-responsive. The apo- but not holo-form probably binds DNA.
Cofactor [4Fe-4S] cluster
Note: Binds 1 [4Fe-4S] cluster per subunit. Following nitrosylation of the [4Fe-4S] cluster binds 1 [4Fe-8(NO)] cluster per subunit.
Subcellular location Cytoplasm.
Ptm The Fe-S cluster can be nitrosylated by nitric oxide (NO).
Upon Fe-S cluster removal intramolecular disulfide bonds are formed.
Similarity Belongs to the WhiB family.
