CC   -!- FUNCTION: Member of the two-component regulatory system LytR/LytS that
CC       regulates genes involved in autolysis, programmed cell death, biofilm
CC       formation and cell wall metabolism. Participates also in sensing and
CC       responding to host defense cationic antimicrobial peptides (HDPs).
CC       Functions as a sensor protein kinase which is autophosphorylated at a
CC       histidine residue and transfers its phosphate group to the conserved
CC       aspartic acid residue in the regulatory domain of LytR. In turn, LytR
CC       binds to the upstream promoter regions of target genes including lrgA
CC       and lrgB, to positively regulate their expression. Possesses also a
CC       phosphatase activity that dephosphorylates and thus inactivates LytR.
CC       {ECO:0000250|UniProtKB:Q53705}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC         histidine.; EC=2.7.13.3; Evidence={ECO:0000250|UniProtKB:Q53705};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- PTM: Autophosphorylated on His-390. {ECO:0000250|UniProtKB:Q53705}.
