RA Lee K., Feinstein J., Cracraft J.; RT "Phylogenetic relationships of the ratite birds: resolving conflicts RT between molecular and morphological data sets."; RL (In) Mindell D.P. (eds.); RL Avian molecular evolution and systematics, pp.1-1, Academic Press, New RL York (1997). 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. CC -!- CATALYTIC ACTIVITY: 4 ferrocytochrome c + O(2) + 4 H(+) = 4 CC ferricytochrome c + 2 H(2)O. CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass CC membrane protein. CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family. CC {ECO:0000305}.
