    The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, phosphorylation of [protein|638D6D2FCCA2A167EFED05CB4E60C2D78D5319AE|PhoP]

    • Paralogous protein(s)

  • [protein|E88978809272FAC2520DB4ABCA0554F8028F3451|WalK], [protein|EA6790EF30D3DDB9670FE52DFD2C5083AB6A48E1|ResE]

    • [SW|Domains]

  • two transmembrane segments
  • [SW|PAS domain], for binding of an intermediate of wall teichoic acid biosynthesis (lipid V composed of poly(glycerol phosphate)) [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|C81F68521F17861D50926D7D8757DC1D2340BC0D|PhoR] [Pubmed|25315493]

    • Effectors of protein activity

  • activity is inhibited by binding of an intermediate of wall teichoic acid biosynthesis (lipid V composed of poly(glycerol phosphate) to the intracellular [SW|PAS domain] of [protein|C81F68521F17861D50926D7D8757DC1D2340BC0D|PhoR] [Pubmed|25315493]
  • the kinase activity is activated by an intermediate in the WTA biosynthetic pathway (product of [protein|72A89412C53703F96F835D26307263F5D1A4AB4E|TagA] or [protein|911A4D957A6C0DFC636A152395119DBFC777DDA2|TagB]) [pubmed|29644746]
