Comments [?]

Function	Probable ATPase of unknown function. Its presence in a non-photosynthetic plant (Epifagus virginiana) and experiments in tobacco indicate that it has an essential function which is probably not related to photosynthesis.
Subcellular location	Plastid, chloroplast stroma.
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, see: PubMed=8082182; Wolfe K.H.; "Similarity between putative ATP-binding sites in land plant plastid ORF2280 proteins and the FtsH/CDC48 family of ATPases."; Curr. Genet. 25:379-383(1994). 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, see: MEDLINE=94363755; PubMed=8082181; Downie S.R., Katz-Downie D.S., Wolfe K.H., Calie P.J., Palmer J.D.; "Structure and evolution of the largest chloroplast gene (ORF2280): internal plasticity and multiple gene loss during angiosperm evolution."; Curr. Genet. 25:367-378(1994).
