CC   -!- FUNCTION: Probable ATPase of unknown function. Its presence in a non-
CC       photosynthetic plant (Epifagus virginiana) and experiments in tobacco
CC       indicate that it has an essential function which is probably not
CC       related to photosynthesis.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Ycf2 family. {ECO:0000305}.
CC   -!- CAUTION: There are two genes for this protein in the chloroplast
CC       inverted repeat; while they are usually identical, in this organism
CC       they are not. The other copy is AC Q8S8V2. {ECO:0000305}.
