The protein
[wiki|Domains]
[wiki|HTH rrf2-type domain] (aa 2-133) (according to UniProt)
[wiki|Cofactors]
Fe-S cluster, required for DNA-binding [Pubmed|21091510]
Structure
[PDB|3LWF] (from Listeria innocua, 29% identity)
[AF|O07573]
Effectors of protein activity
nitric oxide (NO) acts as molecular inducer and results in NsrR release from its DNA targets [Pubmed|19006327]
[4Fe-4S]-NsrR binds around the -35 element of the ''[gene|FAAC0F819AEC8E055CCEE86D93C8DE5584DC4B23|nasD]'' promoter with much higher affinity than apo-NsrR and binding of [4Fe-4S]-NsrR, but not apo-protein, is sensitive to NO [Pubmed|21091510]
