Abstract Carbon dioxide (CO 2), a greenhouse gas is considered to contribute significantly
to climate change and global warming. Environmental changes require to minimize the …

The reaction takes place at a specialized metal center that dramatically increases the acidity
of H2 and leads to a heterolytic splitting of the molecule which is strongly accelerated by the …

Hydrogenases are abundant enzymes that catalyse the reversible interconversion of H2 into
protons and electrons at high rates. Those hydrogenases maintaining their activity in the …

Hydrogenase proteins catalyze the reversible conversion of molecular hydrogen to protons
and electrons. The most abundant hydrogenases contain a [NiFe] active site; these proteins …

Hydrogenases are essential for H2 cycling in microbial metabolism and serve as valuable
blueprints for H2-based biotechnological applications. However, most hydrogenases are …

Molecular hydrogen (H2) is used as an energy source or a way to deposit excess reducing
power by a wide range of microorganisms. Both H2 oxidation and production are catalysed …

Growing concerns over greenhouse gas emissions and energy insecurity caused by the
depletion of conventional fuels have led to a search for sustainable fuel alternatives. As an …

The crystal structure of the membrane-bound O2-tolerant [NiFe]-hydrogenase 1 from
Escherichia coli (Ec Hyd-1) has been solved in three different states: as-isolated, H2 …

Cupriavidus necator owes its popularity to the ability to produce large amounts of the
polyester poly (3-hydroxybutyric acid), or PHB. During the last decades, C. necator has earnt …

Hydrogen oxidizing bacteria (HOB), a type of chemoautotroph, are a group of bacteria from
different genera that share the ability to oxidize H 2 and fix CO 2 to provide energy and …
