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

The review describes four flavin-containing cytoplasmatic multienzyme complexes from
anaerobic bacteria and archaea that catalyze the reduction of the low potential ferredoxin by …

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 …

Hydrogenases (H2ases) catalyze the reversible oxidation of molecular hydrogen and play a
central role in microbial energy metabolism. Most of these enzymes are found in Archaea …

Dark fermentative hydrogen production is an attractive route to the renewable production of
hydrogen for a number of reasons. At least in its initial employment, it would use readily …

Fossil fuels like coal, oil, and natural gases are not renewable on a human time scale and
when combusted they pollute the earth's atmosphere with carbon dioxide. The latter is …

Oxidative phosphorylation involves the coupling of ATP synthesis to the proton-motive force
that is generated typically by a series of membrane-bound electron transfer complexes …

Hydrogenases (H 2 ases) are metalloproteins. The great majority of them contain iron-sulfur
clusters and two metal atoms at their active center, either a Ni and an Fe atom, the [NiFe]-H 2 …

Methane in the seabed is mostly oxidized to CO2 with sulfate as the oxidant before it
reaches the overlying water column. This microbial oxidation takes place within the sulfate …

Abstract rnf genes are widespread in bacteria and biochemical and genetic data are in line
with the hypothesis that they encode a membrane-bound enzyme that oxidizes reduced …
