Protein
Cytochrome c oxidase subunit 2
Gene
ctaC, Mb2223c
Organism
Mycobacterium bovis (strain ATCC BAA-935 / AF2122/97)
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.

Catalytic activityi

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

Cofactori

Copper A By similarity.
Heme group By similarity.
