Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: autophosphorylation, phosphorylation of PhoP
  • Protein family:
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains: two transmembrane segments, C-terminal histidine phosphotransferase domain
  • Modification:
    • autophosphorylation on a His residue in response to the the availability of an intermediate of wall teichoic acid bioynthesis, autophosphorylation is prevented by binding of this intermediate to the intracellular PAS domain of PhoR PubMed
