Cytochrome heme

WebJan 23, 2007 · The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain. WebSubunit I contains two heme centers. The first of these (heme a in cytochrome oxidaes) acts as an electron input device to the second. The second heme (heme a 3 in cytochrome oxidase) is part of a binuclear center, with a Cu (Cu B in cytochrome oxidase) as the other metal. The binuclear center is the site of oxygen reduction.
