RT   transporter in Listeria monocytogenes.";

CC   -!- FUNCTION: Part of the ABC transporter complex OpuCABCD involved in
CC       carnitine uptake. Probably responsible for the translocation of the
CC       substrate across the membrane. Involved, with BetL and GbuABC, in
CC       osmoprotection and cryoprotection of Listeria.
CC       {ECO:0000269|PubMed:11055912}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (OpuCA),
CC       two transmembrane proteins (OpuCB and OpuCD) and a solute-binding
CC       protein (OpuCC). {ECO:0000305|PubMed:11055912}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. {ECO:0000305}.
