CC   -!- FUNCTION: May be involved in proton extrusion. Indirectly promotes
CC       efficient inorganic carbon uptake into plastids (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000255|HAMAP-Rule:MF_01308}.
CC   -!- SIMILARITY: Belongs to the Cema family. {ECO:0000305}.
CC   -!- CAUTION: Young tissue from this organism is photosynthetic and contains
CC       some thylakoids, although the photosynthetic activity does not exceed
CC       the light compensation point. {ECO:0000305}.
