Abstract
Among aerobic prokaryotes, many different terminal oxidase complexes have been described. Sequence comparison has revealed that the aa3-type cytochrome c oxidase and the bo3-type quinol oxidase are variations on the same theme: the heme-copper oxidase. A third member of this family has recently been recognized: the cbb3-type cytochrome c oxidase. Here we give an overview, and report that nitric oxide (NO) reductase, a bc-type cytochrome involved in denitrification, shares important features with these terminal oxidases as well. Tentative structural, functional and evolutionary implications are discussed.
