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.
CC   -!- MISCELLANEOUS: Two proteins of approximately 170 kDa are detected; it
CC       is not clear which parts of the protein are stably expressed.
CC   -!- SIMILARITY: Belongs to the Ycf2 family. {ECO:0000305}.
