Pollut. Bull. 137:119-128(2018). CC -!- FUNCTION: Cytochrome c oxidase is the component of the respiratory CC chain that catalyzes the reduction of oxygen to water. Subunits 1- CC 3 form the functional core of the enzyme complex. CO I is the CC catalytic subunit of the enzyme. Electrons originating in CC cytochrome c are transferred via the copper A center of subunit 2 CC and heme A of subunit 1 to the bimetallic center formed by heme A3 CC and copper B. {ECO:0000256|RuleBase:RU000369}. CC -!- CATALYTIC ACTIVITY: CC Reaction=4 [Fe(II)cytochrome c] + 4 H(+) + O2 = 4 CC [Fe(III)cytochrome c] + 2 H2O; Xref=Rhea:RHEA:11436, Rhea:RHEA- CC COMP:10350, Rhea:RHEA-COMP:14399, ChEBI:CHEBI:15377, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:29033, CC ChEBI:CHEBI:29034; EC=1.9.3.1; CC Evidence={ECO:0000256|RuleBase:RU000369}; CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation. CC {ECO:0000256|RuleBase:RU000369}. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane CC {ECO:0000256|RuleBase:RU000369}; Multi-pass membrane protein CC {ECO:0000256|RuleBase:RU000369}. CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family. CC {ECO:0000256|RuleBase:RU000369}.
