CC   -!- FUNCTION: Iron-sulfur subunit of the cytochrome bc1 complex, an
CC       essential component of the respiratory electron transport chain
CC       required for ATP synthesis. The bc1 complex catalyzes the oxidation of
CC       menaquinol and the reduction of cytochrome c in the respiratory chain.
CC       The bc1 complex operates through a Q-cycle mechanism that couples
CC       electron transfer to generation of the proton gradient that drives ATP
CC       synthesis. {ECO:0000256|ARBA:ARBA00002494}.
