Hydrogen:quinone oxidoreductase

This enzyme belongs to the family of oxidoreductases, specifically those acting on hydrogen as donor with a quinone or similar compound as acceptor. The systematic name of this enzyme class is hydrogen:quinone oxidoreductase. Other names in common use include hydrogen-ubiquinone oxidoreductase, hydrogen:menaquinone oxidoreductase, membrane-bound hydrogenase, and quinone-reactive Ni/Fe-hydrogenase.
