CC   -!- FUNCTION: Member of the two-component regulatory system SaeR/SaeS
CC       involved in the regulation of staphylococcal virulence factors in a
CC       strain-dependent fashion. Probably functions as a membrane-associated
CC       protein kinase that upon sensing the appropriate signal,
CC       autophosphorylates and in turn activates the cytosolic response
CC       regulator SaeR (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + protein L-histidine = ADP + protein N-phospho-L-
CC         histidine.; EC=2.7.13.3;
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- PTM: Autophosphorylated. {ECO:0000250}.
