    The protein

    [SW|Cofactors]

  • [4Fe-4S] cluster, required for DNA-binding [Pubmed|21091510]
  • 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]
