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:0000255|HAMAP-
CC       Rule:MF_01330}.
CC   -!- SIMILARITY: Belongs to the Ycf2 family. {ECO:0000255|HAMAP-
CC       Rule:MF_01330}.
