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 …

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 …

A three-dimensional structure for the monomeric iron-containing hydrogenase (CpI) from
Clostridium pasteurianum was determined to 1.8 angstrom resolution by x-ray …

If the atmosphere of the early Earth was hydrogen-rich, 1 it is reasonable to think that
hydrogenases, the enzymes enabling cells to use molecular hydrogen, were probably …

Background: Many microorganisms have the ability to either oxidize molecular hydrogen to
generate reducing power or to produce hydrogen in order to remove low-potential electrons …

The utilization of hydrogen by micro-organisms as a source of reducing power or of protons
as final electron acceptors is mediated by metalloenzymes called hydrogenases. The need …

The creation of a 1s core hole in a 3d transition metal ion gives rise to an emission spectrum
that can be recorded using a crystal analyzer. K shell X-ray spectroscopy using an analyser …

Formation of stable iron hydrides on more nucleophilic (electron-rich) metal centers than
those found in hydrogenases with CO ligands would inhibit or at least slow down function …

Many microorganisms, such as methanogenic, acetogenic, nitrogen-fixing, photosynthetic,
or sulfate-reducing bacteria, metabolize hydrogen.[1, 2a] Hydrogen activation is mediated by …

Abstract The [FeFe]-and [NiFe]-hydrogenases catalyze the formal interconversion between
hydrogen and protons and electrons, possess characteristic non-protein ligands at their …
