Det sista oxidaset i andningskedjan. Det samlar ihop elektroner som överförts från reducerat cytokrom c och avger dem till molekylärt syre, som sedan reduceras till vatten. Enzymet består av cytokrom a och cytokrom b, två kopparatomer och 13 olika proteinunderenheter, av vilka kodas av mitokondrie-DNA. Ibland kallas det även komplex IV i andningskedjan. EC 1.9.3.1.
A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.
