  • This gene is a member of the following [SW|regulons]

  • [SW|CcpA regulon], [SW|PhoP regulon], [SW|SigB regulon], [SW|SigE regulon]
  • The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of [protein|search|PhoP]
  • [SW|Domains]

  • two transmembrane segments
  • [SW|PAS domain], for binding of an intermediate of wall teichoic acid biosynthesis [Pubmed|25315493]
  • 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 [SW|PAS domain] of [protein|search|PhoR] [Pubmed|25315493]
  • Effectors of protein activity

  • activity is inhibited by binding of an intermediate of wall teichoic acid biosynthesis to the intracellular [SW|PAS domain] of [protein|search|PhoR] [Pubmed|25315493]
