Protein

Cytochrome c oxidase subunit 2

Gene

ctaC

Organism
Corynebacterium diphtheriae (strain ATCC 700971 / NCTC 13129 / Biotype gravis)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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).By similarity

Catalytic activityi

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

Cofactori

Binds 2 copper A ions per subunit.By similarity
