Bacteriol. 187:2066-2076(2005). 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 (Probable). This protein is essential for aerobic CC growth (PubMed:15601708). {ECO:0000269|PubMed:15601708, CC ECO:0000305|PubMed:15601708}. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + H(2)O + (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-tetrahydroxytetrahydrofuran(Side CC 2) + [AI-2-binding protein](Side 1).; EC=7.6.2.13; CC Evidence={ECO:0000305|PubMed:15601708}; 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:0000305|PubMed:15601708}. CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Peripheral CC membrane protein {ECO:0000305}. CC -!- INDUCTION: In the absence of AI-2, repressed by LsrR. Induced by AI-2, CC via release of the LsrR repressor. In the absence of glucose, induced CC by cAMP-CRP by direct binding to the upstream region of the lsr CC promoter. {ECO:0000269|PubMed:15601708, ECO:0000269|PubMed:15743955}. CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. AI-2 CC autoinducer porter (TC 3.A.1.2.8) family. {ECO:0000305}.
