The 3' region of the cpc operon of Synechococcus sp. PCC 7002 has been sequenced, transcriptionally characterized, and analyzed by interposon mutagenesis. The cpc operon contains six genes, 5' cpcB-cpcA-cpcC-cpcD-cpcE-cpcF 3', and gives rise to at least eight (more likely ten) discrete mRNA transcripts. The steady-state levels of transcripts for the cpcE and cpcF genes are very low and are estimated to represent only about 1-2% of the total transcripts arising from the cpc locus. The cpcE gene predicts a protein of 268 amino acid residues, whereas the cpcF gene predicts a protein of 205 amino acid residues. The deduced …
