additional information

Paracoccus denitrificans

gene nosZ, transcription of nosZ takes place concomitantly with that of narG under suboxic conditions. Catalytically functional N2OR is synthesized and active in aerobically raised cells transferred to vials with 7 vol% O2 in headspace, but N2O reduction rates are 10 times higher when anaerobic precultures are subjected to the same conditions. Upon oxygen exposure, there is an incomplete and transient inactivation of N2OR that can be ascribed to its lower ability to compete for electrons compared with terminal oxidases
