CC   -!- FUNCTION: Member of the two-component regulatory system ArlS/ArlR
CC       involved in the regulation of adhesion, autolysis, multidrug resistance
CC       and virulence. ArlS probably functions as a sensor protein kinase which
CC       is autophosphorylated at a histidine residue and transfers its
CC       phosphate group to ArlR (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}.
