Anaerobically induced expression of the nitrite reductase cytochrome c-551 operon from Pseudomonas aeruginosa.
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.
