CC   -!- FUNCTION: Phosphorelay protein which receives a sensory signal from a
CC       sensor kinase and transmit it to LuxO. At low cell density, a
CC       phosphoryl group is transferred from the sensor kinase, probably on
CC       His-56 and this phosphoryl group is further transferred to LuxO.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAC93960.1; Type=Erroneous initiation; Evidence={ECO:0000305};
