Organism
Escherichia coli (strain K12)
Status
Functioni
Cytochrome bo3 ubiquinol terminal oxidase is the component of the aerobic respiratory chain of E.coli that predominates when cells are grown at high aeration. Has proton pump activity across the membrane in addition to electron transfer, pumping 2 protons/electron.3 Publications
