Quinol-dependent nitric oxide reductase (qNOR) catalyzes the reduction of nitric oxide, which is emitted by bacteria, to produce nitrous oxide—an ozone-depleting gas and potent greenhouse gas. The crystal structure of qNOR from Geobacillus stearothermophilus allows a structural comparison with other respiratory enzymes, revealing functionally important similarities and differences between anaerobic and aerobic respiration.
