Cytochrome reductase complex

WebSep 5, 2024 · This process receives further elaboration under Complex III. Complex III, also known as cytochrome c reductase, is made up of cytochrome b, Rieske subunits (containing two Fe-S clusters), and cytochrome c proteins. A cytochrome is a protein involved in electron transfer that contains a heme group. WebComplex I (reduced nicotinamide-adenine dinucleotide phosphate-coenzyme Q reductase) is the largest complex of the respiratory chain, containing about 46 polypeptides. Seven of the polypeptides are encoded by mtDNA, and mutations affecting exclusively the mtDNA genes will be considered separately under the heading of “mitochondrial genetics.”
