CC   -!- FUNCTION: Component of the ubiquinol-cytochrome c reductase complex
CC       (complex III or cytochrome b-c1 complex), which is a respiratory chain
CC       that generates an electrochemical potential coupled to ATP synthesis.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000305}.
