CC   -!- FUNCTION: This protein is one of the nuclear-coded polypeptide
CC       chains of cytochrome c oxidase, the terminal oxidase in
CC       mitochondrial electron transport.
CC   -!- CATALYTIC ACTIVITY: 4 ferrocytochrome c + O(2) + 4 H(+) = 4
CC       ferricytochrome c + 2 H(2)O.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane.
CC   -!- SIMILARITY: Belongs to the cytochrome c oxidase Vb family.
