OX NCBI_TaxID=9654; RN [1] RP NUCLEOTIDE SEQUENCE. RX PubMed=16213754; DOI=10.1016/j.ympev.2005.07.019; RA Bardeleben C., Moore R.L., Wayne R.K.; RT "A molecular phylogeny of the Canidae based on six nuclear loci."; RL Mol. Phylogenet. Evol. 37:815-831(2005). 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: Mitochondrion; mitochondrial inner membrane; CC multi-pass membrane protein (By similarity). CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
