Methylococcus capsulatus (Bath) was shown to contain two distinct hydrogenases, a soluble hydrogenase and a membrane-bound hydrogenase. This is the first report of a membrane-bound hydrogenase in methanotrophs. Both enzymes were expressed apparently constitutively under normal growth conditions. The soluble hydrogenase was capable of reducing NAD(+) with molecular hydrogen. The activities of both soluble and particulate methane monooxygenases could be driven by molecular hydrogen. This confirmed that molecular hydrogen could be used as a source of reducing power for methane oxidation. Hydrogen-driven methane monooxygenase activities tolerated elevated temperatures and moderate oxygen concentrations. The significance of these findings for biotechnological applications of methanotrophs is discussed.
