CC   -!- FUNCTION: This protein is a component of the leucine, isoleucine,
CC       valine, (threonine) transport system, which is one of the two
CC       periplasmic binding protein-dependent transport systems of the high-
CC       affinity transport of the branched-chain amino acids. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the leucine-binding protein family.
CC       {ECO:0000305}.
