Protein attributes
| Sequence length | 363 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Inferred from homology |
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) By similarity. |
| Catalytic activity | 4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O. |
| Cofactor | Copper A By similarity. Heme group By similarity. |
| Subcellular location | Cell membrane; Multi-pass membrane protein Potential. |
| Miscellaneous | Was identified as a high-confidence drug target. |
| Sequence similarities | Belongs to the cytochrome c oxidase subunit 2 family. |
| Sequence caution | The sequence AAB69853.1 differs from that shown. Reason: Erroneous initiation. |
