CC -!- FUNCTION: Part of the ABC transporter complex MalEFGK involved in
CC maltose/maltodextrin import. Responsible for energy coupling to the
CC transport system. {ECO:0000255|HAMAP-Rule:MF_01709}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + D-maltose(out) + H2O = ADP + D-maltose(in) + H(+) +
CC phosphate; Xref=Rhea:RHEA:22132, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17306, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.5.2.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01709};
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (MalK),
CC two transmembrane proteins (MalG and MalK) and a solute-binding protein
CC (MalE). {ECO:0000255|HAMAP-Rule:MF_01709}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01709}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01709}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily.
CC Maltooligosaccharide importer (TC 3.A.1.1.1) family.
CC {ECO:0000255|HAMAP-Rule:MF_01709}.
