WebThe obtained structure adopts the signature pseudosymmetrical heterodimeric architecture of canonical cytochrome bd oxidases formed by the core subunits CydA and CydB. No accessory subunits were identified for this cytochrome bd homolog. 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… lash lounge louisville ky https://oahuhandyworks.com
