Several evolutionary models proposed that molecular hydrogen (H2) was the primary energy source on the early Earth, exerting a major influence on the origin of life. Hydrogenase, the enzyme catalyzing the interconversion of H2 into protons and electrons, is thus considered an ancestral invention, for which the molecular structure and architecture have ...

Properties of the hydrogenase of scenedesmus
Biochimica et Biophysica Acta (BBA) - Specialized Section on Enzymological Subjects, 19641. 1. The adaptation of hydrogenase (EC 1.98.1.1) in Scenedesnus obliquus was inhibited by dithionite, sulfite, arsenite, marphaside, BAL, 2,2′-dipyridyl, and 1,10-phenanthroline. None of these inhibitors had any effect on the active hydrogenase after adaptation. 2. 2.

Biotechnological applications of hydrogenases
Current Opinion in Biotechnology, 2004Hydrogenases have found use in a variety of biotechnological applications, including biohydrogen production, wastewater treatment, the prevention of microbial-induced corrosion and the generation and regeneration of NADP cofactors. In the future, advances in genome mining and screening techniques are likely to identify new hydrogenases for novel ...

[NiFe]-hydrogenases catalyze the reversible conversion of hydrogen gas into protons and electrons and are vital metabolic components of many species of bacteria and archaea. At the core of this enzyme is a sophisticated catalytic center comprising nickel and iron, as well as cyanide and carbon monoxide ligands, which is anchored to the large ...

Maturation of the [NiFe] hydrogenases
Trends in Microbiology, 2001The high degree of similarity that exists between all the [NiFe] hydrogenase operons and the near universality of hydrogen metabolism among microorganisms suggest that the microbial ability to metabolize hydrogen is of great importance and ancient origin. The large number of genes present in these operons, which are mostly involved in the maturation of

The hydrogenase of Proteus vulgaris
Biochimica et Biophysica Acta, 1957Abstract The hydrogenase of Proteus vulgaris was shown by centrifugal behavior and electron microscopic examination to be particulate. All attempts to disrupt the particles by enzymic, chemical or physical means failed. Some chemical analyses of the particles are given.

Biodiversity of Hydrogenases in Frankia
Current Microbiology, 2004Eighteen Frankia strains originally isolated from nine different host plants were used to study the biodiversity of hydrogenase in Frankia. In the physiological analysis, the activities of uptake hydrogenase and bidirectional hydrogenase were performed by monitoring the oxidation of hydrogen after supplying the cells with 1% hydrogen and the evolution ...

Hydrogenases of phototrophic microorganisms
Biochimie, 1986This review surveys recent work done in the laboratory of the author and related laboratories on the properties and possible practical applications of hydrogenases of phototrophic microorganisms. Homogeneous hydrogenase preparations were obtained from purple non-sulfur (Rhodospirillum rubrum S1, Rhodobacter capsulatus B10) and purple sulfur (Chromatium

Molecular Dynamics Studies of Proton Transport in Hydrogenase and Hydrogenase Mimics
2016There is extensive interest in hydrogenases based on their ability to rapidly and efficiently interconvert H2 with protons and electrons, and their (typically) superior function relative to molecular mimics. Understanding the function of enzymes is one approach to implementing design features to make better catalysts and is an approach we have ...
