The genes encoding the 9 kDa and 4 kDa polypeptides of cytochrome b-559 have been located in pea chloroplast DNA by coupled transcription-translation of cloned restriction fragments of chloroplast DNA in a cell-free extract of Escherichia coli and by nucleotide sequence analysis. The genes (psbE and psbF) are located approximately 1.0 kbp downstream of the gene for cytochrome f and are transcribed in the opposite direction, similar to the arrangement in the chloroplast genomes of other higher plants. Nucleotide sequence analysis of this region revealed four open reading frames encoding hydrophobic proteins of 83 (psbE), 39 (psbF), 38 and 40 amino acid residues, which are co-transcribed as a single major RNA of 1.1 kb. The 5' and 3' ends of this RNA have been located by primer extension and S1 nuclease mapping. The 5' end of the RNA is located 140 bp upstream of the initiating ATG codon of psbE and is preceded by typical chloroplast promoter sequences. The 3' end of the RNA is located approximately 515 bp downstream of the TAA stop codon of psbF close to a stable stem-loop structure.
