General annotation (Comments)

Function	Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The transit peptide of the Rieske protein seems to form part of the bc1 complex and is considered to be the subunit 11/IX of that complex By similarity.
Catalytic activity	QH(2) + 2 ferricytochrome c = Q + 2 ferrocytochrome c + 2 H(+).
Cofactor	Binds 1 2Fe-2S cluster per subunit By similarity.
Subunit structure	The bc1 complex contains 11 subunits: 3 respiratory subunits (cytochrome b, cytochrome c1 and Rieske/UQCRFS1), 2 core proteins (UQCRC1/QCR1 and UQCRC2/QCR2) and 6 low-molecular weight proteins (UQCRH/QCR6, UQCRB/QCR7, UQCRQ/QCR8, UQCR10/QCR9, UQCR11/QCR10 and a cleavage product of Rieske/UQCRFS1).
Subcellular location	Mitochondrion inner membrane.
Miscellaneous	The Rieske protein is a high potential 2Fe-2S protein.
Sequence similarities	Contains 1 Rieske domain.
