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   -!- SIMILARITY: Belongs to the Ycf2 family.

Comments: Has been suggested to be a proteolytic ATPase. The most conserved regions
 are in the C-terminus and are similar to the Walker A, B and AAA motifs,

 ORF2280 proteins and the FtsH/CDC48 family of ATPases.";

 This protein is poorly conserved in sequence and tolerates numerous
 inserts and deletions. It has suffered major deletions in at least some
 members of the Passifloraceae, Geraniaceae, Cuscutaceae, Campanulaceae and
 Poaceae (the grasses); however it seems to be intact in other land plants,
