RX PubMed=18248741; DOI=10.1016/j.ympev.2007.11.012; RA Martinsen E.S., Perkins S.L., Schall J.J.; RT "A three-genome phylogeny of malaria parasites (Plasmodium and closely RT related genera): evolution of life-history traits and host switches."; RL Mol. Phylogenet. Evol. 47:261-273(2008). 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: 4 ferrocytochrome c + O(2) + 4 H(+) = 4 CC ferricytochrome c + 2 H(2)O. {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}.
