Abstract:
:The chloroplast gene for the epsilon subunit (atpE) of the CF1/CF0 ATPase in the green alga Chlamydomonas reinhardtii has been localized and sequenced. In contrast to higher plants, the atpE gene does not lie at the 3' end of the beta subunit (atpB) gene in the chloroplast genome of C. reinhardtii, but is located at a position 92 kb away in the other single copy region. The uninterrupted open reading frame for the atpE gene is 423 bp, and the epsilon subunit exhibits 43% derived amino acid homology to that from spinach. Codon usage for the atpE gene follows the restricted pattern seen in other C. reinhardtii chloroplast genes.The genes for the CF0 subunits I (atpF) and IV (atpI) of the ATPase complex have also been mapped on the chloroplast genome of C. reinhardtii. The six chloroplast ATPase genes in C. reinhardtii are dispersed individually between the two single copy regions of the chloroplast genome, an organization strikingly different from the highly conserved arrangement in two operon-like units seen in chloroplast genomes of higher plants.
