Protein

Probable cytochrome c oxidase subunit 2

Gene

ctaC

Organism
Rickettsia conorii (strain ATCC VR-613 / Malish 7)
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

Protein has several cofactor binding sites:
  • Cu cationBy similarityNote: Binds a copper A center.By similarity
  • hemeBy similarity
