[https://www.uniprot.org/uniprot/QCR6_BOVIN QCR6_BOVIN] This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. This protein may mediate formation of the complex between cytochromes c and c1.

== Publication Abstract from PubMed ==
 +
Ubiquinol cytochrome c oxido-reductase (EC. 1.10.2.2, bc1) is an integral membrane protein complex essential to cellular respiration. Structures of the 11-subunit mitochondrial bc1 complex were determined with and without the fungicide famoxadone. Specific inhibition by famoxadone is achieved through a coordinated optimization of aromatic-aromatic interactions where conformational rearrangements in famoxadone and in residues lining the inhibitor-binding pocket produce a network of aromatic-aromatic interactions that mimic the crystal lattice of benzene. The profound aromatic-aromatic interactions as supported by prior mutagenesis provide a structural basis for specific protein-ligand interaction in a hydrophobic environment. Dramatic conformational changes, both in cyt. b and ISP subunits in the inhibitor-protein complex, confer experimental evidence for a functional role of cytochrome b in the induced conformational arrest of ISP and allow the identification of a possible intrasubunit signal transduction pathway that controls the movement of ISP. These results support an inhibitory mechanism that is consistent with the requirement for ISP movement in the electron transfer of this complex.
