The protein
Catalyzed reaction/ biological activity
autophosphorylation, phosphorylation of [protein|638D6D2FCCA2A167EFED05CB4E60C2D78D5319AE|phoP]
ATP + protein L-histidine --> ADP + protein N-phospho-L-histidine (according to UniProt)
[wiki|Domains]
two transmembrane segments
[wiki|PAS domain], for binding of an intermediate of wall teichoic acid biosynthesis (lipid V composed of poly(glycerol phosphate)) [Pubmed|25315493]
[wiki|Histidine kinase domain] (aa 357-575) (according to UniProt)
Structure
[PDB|3CWF] (extracellular domain)  [Pubmed|20008068]
[AF|P23545]
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 [wiki|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 [wiki|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]
