Protein attributes

Sequence length	215 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c.
Catalytic activity	QH2 + 2 ferricytochrome c = Q + 2 ferrocytochrome c + 2 H+.
Cofactor	Binds 1 2Fe-2S cluster per subunit.
Subunit structure	Fungal cytochrome b-c1 complex contains 10 subunits; 3 respiratory subunits, 2 core proteins and 5 low-molecular weight proteins. Cytochrome b-c1 complex is a homodimer.
Subcellular location	Mitochondrion.
Miscellaneous	The Rieske protein is a high potential 2Fe-2S protein.
Sequence similarities	Contains 1 Rieske domain.
