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. Co I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c or a quinol are transferred to the bimetallic center formed by a high-spin heme and copper B.

Catalytic activity

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

Pathway

Energy metabolism; oxidative phosphorylation.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Developmental stage

Bacteroid (nitrogen-fixing endosymbiont).

Induction

By low oxygen levels.

Miscellaneous

This cytochrome oxidase is probably a cbb3-type.

Sequence similarities

Belongs to the heme-copper respiratory oxidase family.
