+==CRYSTAL STRUCTURE OF BOVINE MITOCHONDRIAL CYTOCHROME BC1 COMPLEX, ALPHA CARBON ATOMS ONLY==
-On the basis of x-ray diffraction data to a resolution of 2.9 angstroms, atomic models of most protein components of the bovine cytochrome bc1, complex were built, including core 1, core 2, cytochrome b, subunit 6, subunit 7, a carboxyl-terminal fragment of cytochrome c1, and an, amino-terminal fragment of the iron-sulfur protein. The positions of the, four iron centers within the bc1 complex and the binding sites of the two, specific respiratory inhibitors antimycin A and myxothiazol were, identified. The membrane-spanning region of each bc1 complex monomer, consists of 13 transmembrane helices, eight of which belong to cytochrome, b. Closely interacting monomers are arranged as symmetric dimers and form, cavities through which the inhibitor binding pockets can be accessed. The, proteins core 1 and core 2 are structurally similar to each other and, consist of two domains of roughly equal size and identical folding, topology.

+== Function ==
+[https://www.uniprot.org/uniprot/QCR1_BOVIN QCR1_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.
