CC   -!- FUNCTION: Part of the ABC transporter complex TcyJLN involved in L-
CC       cystine import. Responsible for the translocation of the substrate
CC       across the membrane. {ECO:0000250|UniProtKB:P0AFT2}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (TcyN),
CC       two transmembrane proteins (TcyL) and a solute-binding protein (TcyJ).
CC       {ECO:0000250|UniProtKB:P0AFT2}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P0AFT2}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. HisMQ subfamily. {ECO:0000305}.
