CC   -!- FUNCTION: Plays a role in the regulation of phosphate uptake. In this
CC       role, it may bind, possibly as a chaperone, to PhoR, PhoP or a PhoR-
CC       PhoP complex to promote dephosphorylation of phospho-PhoP, or inhibit
CC       formation of the PhoR-PhoP transitory complex (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PhoU family. {ECO:0000305}.
