Nitrate, nitrite and nitric oxide reductases: from the last universal common ancestor to modern bacterial pathogens

Highlights • Bacterial cytochromes are conserved throughout evolution for the utilization of nitrogen oxides and oxygen. • These metalloproteins support cellular bioenergetics by aiding with ATP synthesis, and quinol and NADH redox balance. • Cytochromes modulate antioxidant and antinitrosative defe...

Zusammenfassung:	Highlights • Bacterial cytochromes are conserved throughout evolution for the utilization of nitrogen oxides and oxygen. • These metalloproteins support cellular bioenergetics by aiding with ATP synthesis, and quinol and NADH redox balance. • Cytochromes modulate antioxidant and antinitrosative defenses, and antibiotic susceptibility. • Cytochromes contribute to bacterial pathogenesis.
