CC   -!- FUNCTION: Catalyzes quinol oxidation with the concomitant reduction of
CC       oxygen to water. Subunit II transfers the electrons from a quinol to
CC       the binuclear center of the catalytic subunit I (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a quinol + O2 = 2 a quinone + 2 H2O; Xref=Rhea:RHEA:55376,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:24646,
CC         ChEBI:CHEBI:132124;
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|PROSITE-
CC       ProRule:PRU00303}; Multi-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 2 family.
CC       {ECO:0000305}.
