CC   -!- FUNCTION: Part of the ABC transporter complex LsrABCD involved in
CC       autoinducer 2 (AI-2) import. Responsible for energy coupling to the
CC       transport system. {ECO:0000250|UniProtKB:P77257}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + (2R,4S)-2-methyl-2,3,3,4-
CC         tetrahydroxytetrahydrofuran-[AI-2-binding protein]Side 1 = ADP +
CC         phosphate + (2R,4S)-2-methyl-2,3,3,4-tetrahydroxytetrahydrofuranSide
CC         2 + [AI-2-binding protein]Side 1.; EC=7.6.2.13;
CC         Evidence={ECO:0000250|UniProtKB:P77257};
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (LsrA),
CC       two transmembrane proteins (LsrC and LsrD) and a solute-binding protein
CC       (LsrB). {ECO:0000250|UniProtKB:P77257}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P77257}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:P77257}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. AI-2
CC       autoinducer porter (TC 3.A.1.2.8) family. {ECO:0000305}.
