[[http://www.uniprot.org/uniprot/A0R056_MYCS2 A0R056_MYCS2]] Part of cytochrome c oxidase, its function is unknown.[PIRNR:PIRNR017385] [[http://www.uniprot.org/uniprot/A0R0M4_MYCS2 A0R0M4_MYCS2]] Cytochrome 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.[RuleBase:RU363061]
