CC   -!- FUNCTION: Member of the two-component regulatory system CiaH/CiaR.
CC       Involved in early steps of competence regulation and in penicillin
CC       susceptibility. Probably phosphorylates CiaR.
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; Multi-pass membrane protein.
