General Information (Source: NCBI Gene,UniProt)

Text mining Term Cytochrome c oxidase (protein family or complex)
UniProt ID Q85SR9_9CUCU
Name Cytochrome c oxidase subunit 1
Gene Names COI
Taxonomy Chaetocnema costulata

General annotation

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 are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B (By similarity).
Subcellular location Mitochondrion inner membrane; Multi-pass membrane protein (By similarity).
