Menaquinol oxidase (H+-transporting) (EC 7.1.1.5, cytochrome aa3-600 oxidase) is an enzyme with systematic name menaquinol:O2 oxidoreductase (H+-transporting).[1][2][3] This enzyme catalyses the following chemical reaction

2 menaquinol + O2 2 menaquinone + 2 H2O

Cytochrome aa3-600, one of the respiratory oxidases from Bacillus subtilis, is a member of the heme-copper family of oxygen reductases.
