OX NCBI_TaxID=305997; RN [1] RP NUCLEOTIDE SEQUENCE. RX PubMed=15683934; DOI=10.1016/j.ympev.2004.10.021; RA Mallarino R., Bermingham E., Willmott K.R., Whinnett A., Jiggins C.D.; RT "Molecular systematics of the butterfly genus Ithomia (Lepidoptera: RT Ithomiinae): a composite phylogenetic hypothesis based on seven RT genes."; RL Mol. Phylogenet. Evol. 34:625-644(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 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 (By similarity). CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
