CC -!- FUNCTION: Probable maltose transporter. Essential for the conversion of
CC starch to sucrose in leaves at night, probably via the export of
CC maltose from the chloroplast (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast inner membrane
CC {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
