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:RU363061}.
CC -!- CATALYTIC ACTIVITY: 4 ferrocytochrome c + O(2) + 4 H(+) = 4
CC ferricytochrome c + 2 H(2)O. {ECO:0000256|RuleBase:RU363061}.
CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC {ECO:0000256|RuleBase:RU363061}.
CC -!- SUBCELLULAR LOCATION: Cell membrane
CC {ECO:0000256|RuleBase:RU363061}; Multi-pass membrane protein
CC {ECO:0000256|RuleBase:RU363061}.
CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
CC {ECO:0000256|RuleBase:RU363061}.
