Abstract
The nitrite reductase gene (denA) and the cytochrome c‐551 gene (denB) are located only 50 bp apart from each other in the Pseudomonas aeruginosa chromosome. We report evidence that these two genes are co‐transcribed as an operon only under anaerobic (denitrifying) conditions. The nucleotide sequence of the promoter (regulatory) region of the operon is highly AT‐rich and contains a sequence closely resembling the consensus FNR binding site in E. coli.Keywords
