RX MEDLINE=22847123; PubMed=12964987; RA Landry C., Geyer L.B., Arakaki Y., Uehara T., Palumbi S.R.; RT "Recent speciation in the Indo-West Pacific: rapid evolution of gamete RT recognition and sperm morphology in cryptic species of sea urchin."; RL Proc. R. Soc. Lond., B, Biol. Sci. 270:1839-1847(2003). 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 ferricytochrome CC c + 2 H(2)O. CC -!- PATHWAY: Respiratory chain; terminal step. CC -!- SUBCELLULAR LOCATION: Integral membrane protein. Mitochondrial CC inner membrane. CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
