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 CC the transport system (Probable). This protein is essential for CC aerobic growth. {ECO:0000269|PubMed:15601708, ECO:0000305}. CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins CC (LsrA), two transmembrane proteins (LsrC and LsrD) and a solute- CC binding protein (LsrB). {ECO:0000305}. CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; CC Peripheral membrane protein {ECO:0000305}. CC -!- INDUCTION: In the absence of AI-2, repressed by LsrR. Induced by CC AI-2, via release of the LsrR repressor. In the absence of CC glucose, induced by cAMP-CRP by direct binding to the upstream CC region of the lsr promoter. {ECO:0000269|PubMed:15601708, CC 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}. CC -!- SIMILARITY: Contains 2 ABC transporter domains. CC {ECO:0000255|PROSITE-ProRule:PRU00434}.
