CC -!- FUNCTION: Cytochrome bo(3) ubiquinol terminal oxidase is the
CC component of the aerobic respiratory chain of E.coli that
CC predominates when cells are grown at high aeration. Has proton
CC pump activity across the membrane in addition to electron
CC transfer, pumping 2 protons/electron.
CC {ECO:0000269|PubMed:19542282, ECO:0000269|PubMed:22843529,
CC ECO:0000269|PubMed:6308657}.
CC -!- SUBUNIT: Heterooctamer of two A chains, two B chains, two C chains
CC and two D chains. {ECO:0000269|PubMed:11017202,
CC ECO:0000269|PubMed:6308657}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane
CC protein.
CC -!- DISRUPTION PHENOTYPE: Increased reduction of the ubiquinone pool
CC (in aerobically grown minimal medium with glucose).
CC {ECO:0000269|PubMed:19542282, ECO:0000269|PubMed:22843529}.
CC -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 3 family.
