  • The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of [SW|Spo0F] as part of the [SW|phosphorelay], but also direct phosphorylation of [SW|Spo0A] [Pubmed|19114652]
  • mainly active in the younger, outer regions of a colony (with [protein|search|KinD]) [Pubmed|21097618]
  • phosphorylates [SW|Spo0A] in response to the presence of surfactin [Pubmed|22882210], this has been refuted [Pubmed|25701730]
  • required for initiation of [SW|sliding] together with [protein|search|KinB] [Pubmed|26152584]

  • C-terminal histidine phosphotransferase domain
  • Modification

  • autophosphorylation on a His residue
  • Effectors of protein activity

  • activity is triggered by potassium leakage [Pubmed|19114652], this has been refuted [Pubmed|25701730]
  • activity is triggered by polyisoprenoid lipids formed by [protein|search|YisP] [Pubmed|20713508]
  • activity is stimulated by the interaction with [protein|search|FloT] [Pubmed|26297017]
  • [SW|Localization]

  • cell membrane (Heterogeneous) [Pubmed|16479537]
  • co-localizes with [protein|search|FloT] in discrete foci in the membrane [Pubmed|20713508]
  • the localization of [protein|search|KinC] in membrane microdomains depends on [protein|search|FloA] and [protein|search|FloT] [Pubmed|22882210], this has been refuted [Pubmed|25701730]
