The cytochrome bd oxidases are terminal oxidases that are present in bacteria and archaea. They reduce molecular oxygen (dioxygen) to water, avoiding the production of reactive oxygen species. In addition to their contribution to the proton motive force, they mediate viability under oxygen-related stress conditions and confer tolerance to nitric oxide, thus contributing to the virulence of pathogenic bacteria. Here you can see the crystal structure of bd oxidase from Geobacillus thermodenitrificans, revealing a pseudosymmetrical subunit fold (PDB code; 5IRS)
