In nature, enzymes termed hydrogenases are capable of producing molecular hydrogen (H2). Special types of these biocatalysts, so-called [FeFe]-hydrogenases, are extremely efficient and therefore o ...
E-Mail An international research team from the Photobiotechnology Research Group at Ruhr-Universität Bochum (RUB) led by Professor Thomas Happe and the Laboratoire de Bioénergétique et Ingénierie des Protéines (CNRS) in Marseille has been able to get to the bottom of this unique feature. They describe the molecular mechanism in Nature Communications on 2 February 2021. Enzyme repeatedly survives the attack unharmed Representatives of the [FeFe]-hydrogenase enzyme group combine protons and electrons to form molecular hydrogen at particularly high turnover rates. Some of them even use s...
(Ruhr University Bochum) Green algae have two almost identical hydrogen-producing enzymes. One has been researched for decades, the other received little attention – until recently. Hydrogen-producing enzymes, so-called hydrogenases, could be a source of regenerative energy. The RUB photobiotechnology working group has now characterized a hydrogenase from the green alga Chlamydomonas reinhardtii that has so far hardly been researched . Green algae have two almost identical hydrogenases. Although they differ in only one single amino acid, they have different properties, the Bochum ...
