WebMar 29, 2024 · This gene encodes a subunit of the cytochrome bc1 complex, which plays an important role in the mitochondrial respiratory chain by transferring electrons from the Rieske iron-sulfur protein to cytochrome c. Mutations in this gene may cause mitochondrial complex III deficiency, nuclear type 6. [provided by RefSeq, Dec 2013] simons in wearWebThe protein chain in cytochrome c is shown in pink tubes and the protein chains in the bc1 complex are shown in yellow tubes. The hemes are shown with spheres at each atom, with the iron atoms in yellow. Notice how the heme group of cytochrome c is pushed close to a heme group in the bc1 complex.
