CC -!- FUNCTION: Part of the ABC transporter complex cysAWTP (TC 3.A.1.6.1)
CC involved in sulfate/thiosulfate import. Probably responsible for the
CC translocation of the substrate across the membrane (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000305}; Multi-pass
CC membrane protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC permease family. CysTW subfamily. {ECO:0000305}.
