    Phenotypes of a mutant

  • defective in [SW|biofilm formation] [Pubmed|22882210]
  • The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of [protein|9896B99346B0D3F6D57F57377DB253B46135A37A|Spo0F] as part of the [SW|phosphorelay], but also direct phosphorylation of [protein|2C54FE2ADC82FF414D732018C90649D477A925AD|Spo0A] [Pubmed|19114652]
  • mainly active in the younger, outer regions of a colony (with [protein|511E71BB1981758857854C8E9BF657287CE60C11|KinD]) [Pubmed|21097618]
  • phosphorylates [protein|2C54FE2ADC82FF414D732018C90649D477A925AD|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|2111AC1AE49D1006E10DC127BF5B7A0327DE94A7|KinB] [Pubmed|26152584]
  • [SW|Domains]

  • two transmembrane segments
  • [SW|PAS domain] (aa 76-147) (according to UniProt)
  • [SW|PAC domain] (aa 148-22) (according to UniProt)
  • [SW|Histidine kinase domain] (aa 221-426) (according to UniProt)
  • 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|E5F32D960F6FF50A7B0E4B268D2296FE1A291512|YisP] [Pubmed|20713508]
  • activity is stimulated by the interaction with [protein|61893B4EB53FBBB9AD8BEEEFFCEFD0FC64544D6F|FloT] [Pubmed|26297017]
  • Structure

  • [PDB|3A0R] (HK-RR complex from Thermotoga maritima, 28% identity) [pubmed|19836334]
  • [SW|Localization]

  • co-localizes with [protein|61893B4EB53FBBB9AD8BEEEFFCEFD0FC64544D6F|FloT] in discrete foci in the membrane [Pubmed|20713508]
  • the localization of [protein|A656321846B2E0D1F39B528E2D8B8E620CCD1148|KinC] in membrane microdomains depends on [protein|11A55829B4C3E8EA434A600FF7B4102F8E5A7DCE|FloA] and [protein|61893B4EB53FBBB9AD8BEEEFFCEFD0FC64544D6F|FloT] [Pubmed|22882210], this has been refuted [Pubmed|25701730]
