Subcellular location

Subcellular Location:
Mitochondrion inner membrane; Single-pass membrane protein.

Function

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.
Catalytic Activity:
Quinol + 2 ferricytochrome c = quinone + 2 ferrocytochrome c + 2 H(+).
