CC -!- FUNCTION: Plays a role in the regulation of phosphate uptake.
CC {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: Mutants are constitutive of alkaline phosphatase
CC and show chemotactic response to phosphate regardless of wheather the
CC cells are starved for phosphate. {ECO:0000269|PubMed:8083184}.
CC -!- SIMILARITY: Belongs to the PhoU family. {ECO:0000305}.
