Reaction: H2 + menaquinone = menaquinol
Other name(s): hydrogen-ubiquinone oxidoreductase; hydrogen:menaquinone oxidoreductase; membrane-bound hydrogenase; quinone-reactive Ni/Fe-hydrogenase
Systematic name: hydrogen:quinone oxidoreductase
Comments: Contains nickel, iron-sulfur clusters and cytochrome b. Also catalyses the reduction of water-soluble quinones (e.g. 2,3-dimethylnaphthoquinone) or viologen dyes (benzyl viologen or methyl viologen).
