CC   -!- FUNCTION: Part of the ABC transporter complex LsrABCD involved in
CC       autoinducer 2 (AI-2) import. Binds AI-2 and delivers it to the LsrC and
CC       LsrD permeases (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (LsrA),
CC       two transmembrane proteins (LsrC and LsrD) and a solute-binding protein
CC       (LsrB). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the bacterial solute-binding protein 2 family.
CC       {ECO:0000305}.
