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 …

Hydrogenase is a paradigm of highly efficient biocatalyst for H 2 production and utilization
evolved in nature. A dilemma is that despite the high activity and efficiency expected for …

Cleaner synthesis of amines remains a key challenge in organic chemistry because of their
prevalence in pharmaceuticals, agrochemicals and synthetic building blocks. Here, we …

Hydrogenases catalyze hydrogen/proton interconversion that is normally electrochemically
reversible (having minimal overpotential requirement), a special property otherwise almost …

Pathogenic microorganisms use various mechanisms to conserve energy in host tissues
and environmental reservoirs. One widespread but often overlooked means of energy …

The reasons for using enzymes as tools for solar fuels research are discussed. Many
oxidoreductases, including components of membrane-bound electron-transfer chains in …

Life relies on the constant exchange of different forms of energy, ie, on energy transduction.
Therefore, organisms have evolved in a way to be able to harvest the energy made …

In the field of applied microbiology, reproducibility and experimental variability are important
factors that influence both basic research as well as process development for industrial …

The splitting of hydrogen (H2) is an energy-yielding process, which is important for both
biological systems and as a means of providing green energy. In biology, this reaction is …

Hydrogenase-1 (Hyd-1) from E. coli poses a conundrum regarding the properties of
electrocatalytic reversibility and associated bidirectionality now established for many redox …
