CC   -!- FUNCTION: Member of the two-component regulatory system SaeR/SaeS.
CC       Probably functions as a membrane-associated protein kinase that upon
CC       sensing the appropriate signal, autophosphorylates and in turn
CC       activates the cytosolic response regulator SaeR (By similarity).
CC       {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}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAW53762.1; Type=Erroneous initiation; Evidence={ECO:0000305};
