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}.
