General annotation (Comments)

Function	Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. Subunit 2 transfers the electrons from cytochrome c via its binuclear copper A center to the bimetallic center of the catalytic subunit 1 By similarity. RuleBase RU000457 SAAS SAAS015964
Cofactor	Copper A By similarity. RuleBase RU000457 SAAS SAAS015964
Subcellular location	Mitochondrion inner membrane; Multi-pass membrane protein By similarity RuleBase RU000457 SAAS SAAS015964.
Sequence similarities	Belongs to the cytochrome c oxidase subunit 2 family. RuleBase RU000457
