Function
CYOB_ECOLI Cytochrome bo(3) 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. Protons are probably pumped via D- and K- channels found in this subunit (PubMed:11017202).[1] [2] [3]
