RA Utiger U., Helfenberger N., Schaetti B., Schmidt C., Ruf M., RA Ziswiler V.; RT "Molecular systematics and phylogeny of Old and New World ratsnakes, RT Elaphe auct., and related genera (Reptilia, Squamata, Colubridae)."; RL Russ. J. Herpetol. 9:105-124(2002). 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 (By similarity). CC -!- CATALYTIC ACTIVITY: 4 ferrocytochrome c + O(2) = 4 ferricytochrome CC c + 2 H(2)O. CC -!- PATHWAY: Respiratory chain; terminal step. CC -!- SUBCELLULAR LOCATION: Integral membrane protein. Mitochondrial CC inner membrane (By similarity). CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
