Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
  • Cofactor(s): [4Fe-4S] cluster, required for DNA-binding PubMed
  • Effectors of protein activity:
    • nitric oxide (NO) acts as molecular inducer and results in NsrR release from its DNA targets PubMed
    • [4Fe-4S]-NsrR binds around the -35 element of the nasD promoter with much higher affinity than apo-NsrR and binding of [4Fe-4S]-NsrR, but not apo-protein, is sensitive to NO PubMed
