Abstract excerpt
The activity of the promoters involved in transcription of the genes (nirS, nirQ and norC) required for anaerobic reduction of nitrite and nitric oxide was investigated in NIR- and NOR-deficient mutants of Pseudomonas aeruginosa. The transcriptional activity of these three promoters was induced by nitrite in a wild-type strain and the activity was low in an nirS mutant. In norCBD and nirQOP mutants, which were...
