OX NCBI_TaxID=46244; RN [1] RP SEQUENCE FROM N.A. RC STRAIN=BOGOTA; RA Gleason J.M., Caccone A., Moriyama E.N., Powell J.R.; RL Submitted (MAR-1996) to the EMBL/GenBank/DDBJ databases. 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.
