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 …

Reductions play a key role in organic synthesis, producing chiral products with new
functionalities. Enzymes can catalyse such reactions with exquisite stereo‐, regio‐and …

Biocatalysis can empower chemical, pharmaceutical, and energy industries, where the use
of enzymes facilitates low-energy, sustainable methods of producing high-value chemicals …

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

Bacterial respiration of nitrate is a natural process of nitrate reduction, which has been
industrialized to treat anthropic nitrate pollution. This process, also known as “microbial …

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 …

Complex I of respiratory chains is an energy transducing enzyme present in most bacteria,
mitochondria and chloroplasts. It catalyzes the oxidation of NADH and the reduction of …

Hydrogenases control the H2-related metabolism in many microbes. Most of these enzymes
are prone to immediate inactivation by O2. However, a few members of the subclass of …

Direct electron transfer (DET)-type bioelectrocatalysis, which couples the electrode reactions
and catalytic functions of redox enzymes without any redox mediator, is one of the most …

Cyanobacteria have garnered interest as potential cell factories for hydrogen production. In
conjunction with photosynthesis, these organisms can utilize inexpensive inorganic …
