CC   -!- FUNCTION: Part of the ABC transporter complex GltIJKL involved in
CC       glutamate and aspartate uptake. Probably responsible for the
CC       translocation of the substrate across the membrane.
CC       {ECO:0000250|UniProtKB:P0AER5}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (GltL),
CC       two transmembrane proteins (GltJ and GltK) and a solute-binding protein
CC       (GltI). {ECO:0000250|UniProtKB:P0AER5}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P0AER5}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. HisMQ subfamily. {ECO:0000305}.
