Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • autophosphorylation, phosphorylation of Spo0F, regulates the onset of sporulation by inhibiting the activity of Spo0A until matrix, or a component therein, is sensed PubMed
    • dual role as a phosphatase or a kinase, activity is linked to the presence of extracellular matrix in the biofilms PubMed
    • mainly active in the younger, outer regions of a colony (with KinC) PubMed
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
    • two transmembrane segments, between them the extracellular CACHE domain for L-malate binding PubMed
    • C-terminal histidine phosphotransferase domain
    • see PubMed for a scheme of the domain organization
  • Modification: autophosphorylation on a His residue
  • Cofactor(s):
  • Effectors of protein activity:
    • activity is stimulated by direct or indirect interaction with Med PubMed
    • L-malate seems to trigger KinD activity PubMed
    • kinase activity is triggered and phosphatase activity is decreased by increased osmotic pressure PubMed
