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
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein
