| Abstract: | The nucleotide sequences of the genes for the beta and epsilon subunits of tobacco chloroplast ATPase have been determined. The coding regions for the beta and epsilon subunits contain 1494 bp (498 codons) and 399 bp (133 codons), respectively. The 3' end of the beta-coding region overlaps by one nucleotide with the 5' end of the epsilon-coding region. The overlapping termination and initiation codons are ATGA. The beta and epsilon genes are cotranscribed as a 2.7-kb polycistronic mRNA. The amount of the beta and epsilon mRNA in the chloroplast is about one-twentieth that of the LS mRNA. |
