Short name: Cyt_bc1_su8

Overlapping homologous superfamilies

Family relationships


The ubiquinol-cytochrome C reductase complex (cytochrome bc1 complex) is a respiratory multi-enzyme complex [PMID: 9651245], which recognises a mitochondrial targeting presequence. The bc1 complex contains 11 subunits: 3 respiratory subunits (cytochrome b, cytochrome c1 and Rieske protein), 2 core proteins and 6 low molecular weight proteins. This family represents the 9.5 kDa subunit of the complex, known as subunit 8 or protein QP-C [PMID: 12709789]. This subunit together with cytochrome B binds to ubiquinone.
