Abstract
Bacterial formation of carcinogenic N-nitroso compounds may play a role in the etiology of human cancer. Biochemical and immunological studies in denitrifying bacteria (Pseudomonas aeruginosa) strongly support the identification of cytochrome cd(1)-nitrite reductase as the enzyme responsible for the catalysis of nitrosation through the production of nitric oxide or NO(+)-like species. Interestingly, electron paramagnetic resonance studies have shown that large quantities of nitric oxide or NO(+)-species were also produced by non-denitrifying enterobacteria (Escherichia coli, Proteus morganii).
