CC   -!- FUNCTION: Part of the ABC transporter complex CmpABCD involved in
CC       bicarbonate transport. Responsible for energy coupling to the transport
CC       system (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (CmpC and
CC       CmpD), a transmembrane protein (CmpB) and a solute-binding protein
CC       (CmpA). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Peripheral
CC       membrane protein {ECO:0000305}.
CC   -!- INDUCTION: By carbon dioxide-limited conditions, probably via CmpR.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily.
CC       Nitrate/nitrite/cyanate uptake transporter (NitT) (TC 3.A.1.16) family.
CC       {ECO:0000305}.
