== Function ==
[https://www.uniprot.org/uniprot/COX1B_PARDE COX1B_PARDE] Subunit 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). This cytochrome c oxidase shows proton pump activity across the membrane in addition to the electron transfer.
