Most methanogenic archaea reduce CO2 with H2 to CH4. For the activation of H2, they use
different [NiFe]-hydrogenases, namely energy-converting [NiFe]-hydrogenases …

Methanogenic archaea are known to contain two types of [NiFe] hydrogenases designated
F420‐reducing hydrogenase and F420‐non‐reducing hydrogenase. We report here that …

Abstract [Fe] hydrogenase (iron–sulfur-cluster-free hydrogenase) catalyzes the reversible
reduction of methenyltetrahydromethanopterin (methenyl-H 4 MPT+) with H 2 to methylene …

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 …

Hydrogenases are metalloenzymes subdivided into two classes that contain iron-sulfur
clusters and catalyze the reversible oxidation of hydrogen gas (H 2⇆ 2H++ 2e−). Two metal …

Providing an abundant, clean, and secure renewable energy source is one of the key
technological challenges facing mankind. Resurgence in the chemistry and biochemistry of …

Biological formation and consumption of molecular hydrogen (H2) are catalyzed by
hydrogenases, of which three phylogenetically unrelated types are known:[NiFe] …

The activation of molecular hydrogen is of interest both from a chemical and biological
viewpoint. The covalent bond of H2 is strong (436 kJ mol− 1). Its cleavage is catalyzed by …

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 …

Molecular hydrogen is an important intermediate in the degradation of organic matter by
microorganisms in anoxic habitats such as freshwater and marine sediments, wet land soils …
