A putative cytochrome c biogenesis gene in Synechocystis sp. PCC 6803.


A gene (orf334) with homology to chloroplast ycf5 (ccsA) was isolated from the cyanobacterium Synechocystis PCC 6803. The mRNA level of orf334 decreases in the dark and increases rapidly upon illumination. Transcription is initiated 69 nucleotides upstream of the start site of translation. The deduced amino acid sequence of orf334 has limited identity with… (More)
