The role of molybdenum in the formate dehydrogenase of methanobacterium formicicum
… oxidation products of the pterin cofactor in the formate dehydrogenase of Methanobacterium formicicum revealed that the cofactor is a 6-substituted pterin similar to the molybdopterin of xanthine oxidase. In contrast to the molybdopterin from xanthine oxidase the formate dehydrogenase cofactor was …

A 'HYBRID' APPROACH FOR THE CHARACTERIZATION OF POSSIBLE PHYSIOLOGICAL ROLES OF ARABIDOPSIS THALIANA FORMATE DEHYDROGENASE FDH
Essendo organismi sessili, le piante non possono fuggire, ma devono costantemente far fronte e diversi stress, come per esempio eccessi di luce o la continua esposizione ai microrganismi. L’enzima formato deidrogenasi (FDH) catalizza l'ossidazione del formato (HCOO-) in anidride carbonica (CO2) …

Increasing the temperature stability of environmentally friendly drilling and completion fluids based on organic brine.
Formates provide an already superior system, designed to complement synthetic polymers and extend their temperature capabilities as drilling fluids. However, as HPHT drilling continues to move into more harsh environments with expected bottom-hole temperatures of over 300°C; further research is …

A biochemical and physiological characterization of coenzyme F420-reducing hydrogenase from Methanobacterium formicicum
… M. formicicum contained a coenzyme F₄₂₀-mediated formate hydrogenlyase system. Formate hydrogenlyase activity was reconstituted with coenzyme F₄₂₀-reducing hydrogenase, coenzyme F₄₂₀-reducing formate dehydrogenase, and coenzyme F₄₂₀, all purified from M. formicicum. The reconstituted system …

Investigating [NiFe]-hydrogenases in γ-Proteobacteria
… that functions in partnership with a formate dehydrogenase as a formate hydrogenlyase (FHL). This FHL complex generates H2 and CO2 from the disproportionation of formate (CHOO- + H+ ↔ H2 + CO2). In this Thesis, genetic and biochemical characterisation of Pectobacterium atrosepticum …

Earth-Abundant Metal Complexes Binding N-Heterocyclic Carbene-Based Ligands for the Photocatalytic Carbon Dioxide Reduction Reaction
… fuels. The light-driven reduction of CO2 to formate and CO is a practical approach for generating fuels from a greenhouse gas, as formate is directly usable in fuel cells, while CO could be used to produce diesel fuels via the Fischer-Tropsch process. However, a robust and efficient …

Metabolism of Gallic Acid by Eubacterium Oxidoreducens
… Extracts of cells grown on gallate and formate contained formate dehydrogenase (EC 1.2.1.43) and hydrogenase (EC 1.88.99.1), which were both NADP-linked. These results suggest that the oxidation of formate or H$\sb2$ may be indirectly linked to the reduction of phloroglucinol. A …

Stable isotope probing of hyperthermophilic filamentous microbial communities in Octopus Spring, Yellowstone National Park
… situ conditions with labeled bicarbonate, formate, or acetate. Lipids from the biomass were extracted and analyzed using gas chromatography-mass spectroscopy (GC-MS) and gas chromatography-isotope ratio monitoring-mass spectroscopy(GC-IRMS). We observed incorporation of ¹³C-labeled acetate …

Reaction chemistry of C₁ hydrocarbon fragments and oxygenates on Cr₂O₃ (101̅2)
… Cannizzaro-type process with dehydrogenation to formate, and hydrogenation to methoxide. Methoxide hydrogenation produces methane and methanol near 670 K. Formate decomposition occurs at 720 K, producing acetylene, carbon monoxide, carbon dioxide and formic acid. The site requirements for these …
