Scientists unlock how hydrogen-sensing proteins could improve clean fuel technology
Researchers have identified how certain proteins detect hydrogen by changing shape, a discovery that could accelerate development of hydrogen sensors and catalysts for the clean energy industry. The finding reveals that the same molecular components can perform vastly different functions depending on their protein structure—opening new design strategies for hydrogen-based energy systems.
Originaltitel: Secondary structure changes as the potential H<sub>2</sub> sensing mechanism of group D [FeFe]-hydrogenases
<p>[FeFe]-hydrogenases function as both H2 catalysts and sensors. While catalysis is well investigated, details regarding the H-2 sensing mechanism are limited. Here, we relate protein structure changes to H-2 sensing, similar to light-driven bio-sensors. Our results highlight how identical cofactors incorporated in alternative protein scaffolds serve different functions in nature.</p>
