>TIGR01432 QOXA cytochrome aa3 quinol oxidase, subunit II; InterPro: IPR006332 Members of this family catalyze the oxidation of quinol with the concomitant reduction of molecular oxygen to water. This acts as the terminal electron acceptor in the respiratory chain. This subunit contains two transmembrane helices and a large external domain responsible for the binding and oxidation of quinol. QuoX is (presently) only found in Gram-positive bacteria of the Bacillus/Staphylococcus group . Like CyoA, the ubiquinol oxidase found in proteobacteria, the residues responsible for the ligation of Cu(a) and cytochrome c (found in the related cyt. c oxidases) are absent. Unlike CyoA, QoxA is in complex with a subunit I which contains cytochromes similar to the cytochrome c oxidases (as opposed to cytochromes b).; GO: 0016682 oxidoreductase activity acting on diphenols and related substances as donors oxygen as acceptor, 0006122 mitochondrial electron transport ubiquinol to cytochrome c.
