CC -!- FUNCTION: Cytochrome bo(3) ubiquinol terminal oxidase is the component
CC of the aerobic respiratory chain of E.coli that predominates when cells
CC are grown at high aeration. Has proton pump activity across the
CC membrane in addition to electron transfer, pumping 2 protons/electron.
CC {ECO:0000256|ARBA:ARBA00025694}.
CC -!- SUBUNIT: Heterooctamer of two A chains, two B chains, two C chains and
CC two D chains. {ECO:0000256|ARBA:ARBA00011700}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the cytochrome c oxidase bacterial subunit 4
CC family. {ECO:0000256|ARBA:ARBA00008079}.
