The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • binds multiple regions in the oriC region, required for recruitment of proteins needed to load the replicative helicase DnaC
  • Protein family: dnaA family (according to Swiss-Prot)
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains: AAA+ domain
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
    • SirA displaces DnaA from the replication origin PubMed
    • YabA inhibits co-operative binding of DnaA to the oriC DNA PubMed
    • DnaA helix formation (and thus replication initiation) is inhibited by the interaction of Soj with the AAA+ domain of DnaA PubMed
    • interaction with DnaD inhibits the ability of DnaA to cooperatively bind to DNA PubMed
