UniProt functional annotation for Q5SLI2

UniProt code: Q5SLI2.

Organism: Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579).
Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Thermales; Thermaceae; Thermus.
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 + O(2) + 4 H(+) = 4 ferricytochrome c + 2 H(2)O.
Cofactor: Copper A (By similarity).
Subcellular location: Membrane; Multi-pass membrane protein (By similarity).
Similarity: Belongs to the cytochrome c oxidase subunit 2 family.
