Identification
NameCytochrome c oxidase subunit 1
Synonyms
  • Cytochrome c oxidase polypeptide I
Gene NameCOX1
Enzyme Class
Biological Properties
General FunctionInvolved in iron ion binding
Specific FunctionCytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1- 3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B
