We have isolated an Arabinopsis thaliana cDNA encoding a highly hydrophobic membrane protein of 589 amino acids which contains 12 potential transmembrane helices and shows a high degree of similarity (43.5% identity, 66.2% similarity) to the ATP/ADP translocase of the Gram-negative bacterium Rickettsia prowazekii, an obligate intracellular parasite responsible for the epidemic typhus. This rickettsial translocator resides in the cytoplasmic membrane and allows the bacterium to exploit the host cytoplasmic ATP pool. We hypothesize that the A. thaliana homolog of the R. prowazekii ATP/ADP translocase is the functional eukaryotic equivalent and resides in the plastid inner envelope membrane where it functions as an ATP importer.
