Gases like H2, N2, CO2, and CO are increasingly recognized as critical feedstock in “green”
energy conversion and as sources of nitrogen and carbon for the agricultural and chemical …

Biohydrogen is a green and eco-friendly energy carrier with the potential to reduce our
dependency on fossil fuels. Renewable biohydrogen production from waste biomass …

Dark fermentation is considered as a promising method for sustainable hydrogen
generation. Microorganisms play a pivotal role in hydrogen production efficiency. Strains …

Hydrogen is an important industrial material and ideal secondary energy. It is widely used in
petrochemical, electronics, metallurgy, food processing, fine organic synthesis, and clean …

Ever since the discovery of hydrogenases over 90 years ago (Stephenson and Stickland,
1931), their structure and mechanism of action have been intensively investigated. Of the …

[FeFe]-hydrogenases are complex metalloenzymes, key to microbial energy metabolism in
numerous organisms. During anaerobic metabolism, they dissipate excess reducing …

Hydrogenases are redox enzymes that catalyze the conversion of protons and molecular
hydrogen (H2). Based on the composition of the active site cofactor, the monometallic [Fe] …

Abstract [FeFe]-hydrogenases are efficient H2-catalysts, yet upon contact with dioxygen their
catalytic cofactor (H-cluster) is irreversibly inactivated. Here, we combine X-ray …

Hydrogen with high energy content is considered to be a promising alternative clean energy
source. Biohydrogen production through microbes provides a renewable and immense …

[FeFe] hydrogenases, metalloenzymes catalyzing proton/dihydrogen interconversion, have
attracted intense attention due to their remarkable catalytic properties and (bio-) …
