Cytochrome c oxidase belongs to the superfamily of terminal oxidases known as the heme-copper oxidases. Members of this superfamily are redox driven proton pumps that couple ... Cytochrome bd (OPM family 805) is a tri-heme oxidase as it is compound by cytochromes b558, b595 and d. Its main function is the reduction of O2 to H2O. It is thought that it uses a di-heme active site, which is formed by the hemes of cytochromes b595 and d. These two cytochromes are considered high-spin complexes, what is directly related to the electrons' spin. While other respiratory terminal oxidases which catalyze that same reaction have a heme-copper active sit…
