Sentences with phrase «of hydrogenase»

Harnessing the power of hydrogenase could be key for creating renewable energy.

In nature, hydrogen (H2) molecules store energy and release it as needed with the aid of hydrogenase enzymes.

When they put it all together and infected salmonella bacteria with the remade viruses, the new guide proteins helped assemble the spheres and inserted roughly 100 copies of the hydrogenase into the interior of each one.

But with microbes, it is possible to intervene genetically in ways that encourage the activation of hydrogenase enzymes.

Not exact matches

Instead of contacting the hydrogenase directly to the electrode, an immobilization in a redox hydrogel shall protect the construct.

Under working conditions the hydrogel - modified fuel cell is able to convert chemical energy from hydrogen into electrical energy over several weeks, while in absence of the hydrogel, the hydrogenase is deactivated within seconds.

Normally, no hydrogenase (a natural enzyme that promotes the formation of gaseous hydrogen) is involved in the process.

In fact, as the team reports, the setup increased the efficiency of H2 production 100-fold over previous attempts with hydrogenases.

«If knocking out this other hydrogenase also drastically reduces long - term survival, the enzyme might end up being an excellent next - generation drug target in latent TB infections, which around one - third of the world's population suffer.

They observed the structure of specific enzymes — hydrogenases — to understand how they could accomplish hydrogenation using simple, Earth - abundant materials.

«After looking at hydrogenases, we wanted to check if we could make artificial molecules that mimics these enzymes using the same type of common materials, like iron and manganese,» explained Dr. Abhishek Dubey, the first author of this study.

So they genetically engineered Xanthobacter, giving them an enzyme called a hydrogenase, which allows them to feed on H2 to make a form of cellular energy called ATP.

The basic reaction catalyzed by the hydrogenases is the interconversion of H2 molecules and protons and electrons (H2 ⇔ 2H + +2 e --RRB-.

Pacific Northwest National Laboratory catalysis scientists Dr. Wendy Shaw and Dr. Monte Helm led a workshop on hydrogenase mimics, important components of fuel cells that catalyze hydrogen production and use.

Because the hydrogenases found in nature don't last as long as ones that are built out of tougher chemicals (think paper versus plastic), the researchers wanted to pull out the active portion of the biological hydrogenase and redesign it with a stable chemical backbone.

«We looked at the hydrogenase and asked what is the important part of this?»

Hydrogenases are natural catalysts that drive the reversible conversion of protons into hydrogen.

The program focuses on development of transition - metal complexes that are inspired by the natural photosynthetic enzymes such as nitrogenases, hydrogenases, and the oxygen - evolving complex of photosystem II with the goal of designing catalysts that are chemically stable, active, and highly selective for specific chemical targets.

Schematic representation of a bio fuel cell involving hydrogenase and laccase enzymes.
