CC -!- FUNCTION: Part of the ABC transporter complex MalEFGK involved in
CC trehalose/maltose import. Responsible for the translocation of the
CC substrate across the membrane. {ECO:0000269|PubMed:11453995,
CC ECO:0000269|PubMed:8759837}.
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:0000269|PubMed:11453995, ECO:0000269|PubMed:12454482}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:11453995};
CC Multi-pass membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441,
CC ECO:0000269|PubMed:11453995}.
CC -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC permease family. {ECO:0000305}.
