hydrogenase การใช้

• Even certain enzymes, the hydrogenase, operate via hydride intermediates.
• Another solution includes the entrapment of hydrogenase in a conductive polymer.
• For a well designed cell the largest overpotential is the hydrogenase enzyme.
• The active site of [ NiFe ] hydrogenase in the oxidized form.
• With regards to structural advantages, hydrogenase is highly selective for its substrate.
• Different redox states of [ NiFe ] hydrogenase's metal active site.
• The complex is a precursor to hydrogenase mimics.
• Several species of methanogens have been characterized that express enzymes in the Hmd hydrogenase family.
• The hydrogenase is attached to a surface which also extends the lifetime of the enzyme.
• An alternative is to form films with graphite particles adsorbed with hydrogenase inside a polymer matrix.
• High activities of the soluble heterodisulfide reductase HdrABC and the hydrogenase MvhADG were found in the cytoplasm.
• Another way of coupling hydrogenase to the nanotubes was to covalently bind them to avoid a time delay.
• This has led to intense research focusing on use of [ FeFe ] hydrogenase for sustainable production of H 2.
• Illustration of the [ NiFe ] hydrogenase active site inhibited by CO . Top-down view ( left ).
• 2014  Ruhr University and Max Planck Institute Enhance hydrogen production of microalgae by redirecting electrons from photosystem I to hydrogenase.
• The hydrogenase and hydratase units of DBP exist as dimers, necessary for correct folding and therefore function of the enzyme.
• [NiFe ] hydrogenase has a Mg 2 + cation bonded in the C-terminus region of the larger subunit.
• Only under nitrogen-deficient conditions is nitrogenase activity sufficient to overcome uptake hydrogenase activity, resulting in net generation of hydrogen.
• The cumbersome name distinguishes this hydrogenase from the so-called Fe-only hydrogenases that do contain Fe-S cluster.
• Among the hydrogenase family of enzymes, Hmd is unique in that it does not directly reduce CO 2 to CH 4.
