The ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex) is part of the mitochondrial respiratory chain. This subunit, together with cytochrome b, binds to ubiquinone. In plants, the b-c1 complex contains 10 subunits: 3 respiratory subunits, 2 core proteins and 5 low-molecular weight proteins.

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.
