Protein
Quinol oxidase subunit 2
Gene
qoxA, BSU38170, ipa-37d
Organism
Bacillus subtilis (strain 168)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth. Subunit II transfers the electrons from a quinol to the binuclear center of the catalytic subunit I By similarity.

Catalytic activityi

Ubiquinol-8 + O2 = Ubiquinone-8 + H2O.
