CC -!- FUNCTION: High-affinity uptake of maltose and maltotriose. Also
CC transports alpha-methylglucoside, glucose and turanose but not
CC melezitose or trehalose (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- INDUCTION: By maltose and maltotriose. Repressed by glucose (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Sugar
CC transporter (TC 2.A.1.1) family. {ECO:0000305}.
