CC -!- FUNCTION: Cytochrome c oxidase is the component of the respiratory CC chain that catalyzes the reduction of oxygen to water. Subunits 1-3 CC form the functional core of the enzyme complex. Subunit 2 transfers the CC electrons from cytochrome c via its binuclear copper A center to the CC bimetallic center of the catalytic subunit 1. CC {ECO:0000256|RuleBase:RU000457, ECO:0000256|SAAS:SAAS00709549}. CC -!- COFACTOR: CC Name=Cu cation; Xref=ChEBI:CHEBI:23378; CC Evidence={ECO:0000256|RuleBase:RU000457}; CC Note=Binds a copper A center. {ECO:0000256|RuleBase:RU000457}; CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|RuleBase:RU000457, ECO:0000256|SAAS:SAAS00709542}; Multi- CC pass membrane protein {ECO:0000256|RuleBase:RU000457, CC ECO:0000256|SAAS:SAAS00709542}. CC -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 2 family. CC {ECO:0000256|RuleBase:RU000457, ECO:0000256|SAAS:SAAS00709553}.
