CC -!- FUNCTION: Acts as a receptor for citrate and mediates taxis away from
CC phenol. Also mediates an attractant response to metal-citrate
CC complexes.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC -!- PTM: Methylation level is increased by citrate and decreased by phenol.
CC -!- SIMILARITY: Belongs to the methyl-accepting chemotaxis (MCP) protein
CC family. {ECO:0000305}.
