CC   -!- FUNCTION: Part of the ABC transporter complex MalEFGK involved in
CC       maltose/maltodextrin import. Binds maltose and higher maltodextrins.
CC       {ECO:0000250|UniProtKB:P0AEX9}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (MalK),
CC       two transmembrane proteins (MalG and MalF) and a solute-binding protein
CC       (MalE). {ECO:0000250|UniProtKB:P0AEX9}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250|UniProtKB:P0AEX9}.
CC   -!- SIMILARITY: Belongs to the bacterial solute-binding protein 1 family.
CC       {ECO:0000305}.
