Ubiquinol oxidase (H+-transporting) (EC 1.10.3.10, cytochrome bb3 oxidase, cytochrome bo oxidase, cytochrome bd-I oxidase) is an enzyme with systematic name ubiquinol:O2 oxidoreductase (H+-transporting).[1][2][3][4] This enzyme catalyses the following chemical reaction
- 2 ubiquinol + O2 + n H+in 2 ubiquinone + 2 H2O + n H+out
Ubiquinol oxidase contains a dinuclear centre comprising two hemes, or heme and copper.
