UniProt functional annotation for P08306

UniProt code: P08306.

Organism: Paracoccus denitrificans.
Taxonomy: Bacteria; Proteobacteria; Alphaproteobacteria; Rhodobacterales; Rhodobacteraceae; Paracoccus.
Function: Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).
Catalytic activity: 4 ferrocytochrome c + O(2) + 4 H(+) = 4 ferricytochrome c + 2 H(2)O.
Cofactor: Name=binuclear copper center (CuA); Xref=ChEBI:CHEBI:47357; Note=Binds a binuclear copper A center per subunit.;
Subcellular location: Cell inner membrane; Multi-pass membrane protein.
Similarity: Belongs to the cytochrome c oxidase subunit 2 family. {ECO:0000305}.
