General annotation (Comments)

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 + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O.

Cofactor

Copper A.

Heme group.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the cytochrome c oxidase subunit 2 family.

Contains 1 cytochrome c domain.
