    The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of Spo0F
  • mainly active in the older, inner regions of a colony (with KinA) PubMed
  • sensing potassium level in the medium during initiation of sliding PubMed

    • Domains

  • six transmembrane segments, C-terminal histidine phosphotransferase domain
  • selectivity filter sequence of potassium channels that is required for sliding but not for sporulation PubMed

    • Modification

  • autophosphorylation on a His residue

    • Effectors of protein activity

  • activity is triggered at low respiratory activity, this depends on a functional interaction with the respiration apparatus PubMed

    • Structure
