A gas chromatographic-mass spectrometric technique for studying simultaneous hydrogen-deuteron exchange and para-orthohydrogen conversion in hydrogenases of Desulfovibrio vulgaris Hildenborough

Autor: Paul A. Lespinat, Yves Berlier, Bernard Dimon

Publikováno v: Analytical Biochemistry. 188:427-431

An original gas chromatographic-mass spectrometric technique is described for studying simultaneous dihydrogen-deuteron exchange and para-ortho H2 conversion catalyzed by different Desulfovibrio hydrogenases. Para and orthohydrogens are separated on

The relationship between hydrogen metabolism, sulfate reduction and nitrogen fixation in sulfate reducers

Autor: Jean LeGall, René Toci, Yves Berlier, G. Fauque, Gerard Denariaz, Paul A. Lespinat

Publikováno v: Journal of Industrial Microbiology. 1:383-388

Hydrogenase and nitrogenase activities of sulfate-reducing bacteria allow their adaptation to different nutritional habits even under adverse conditions. These exceptional capabilities of adaptation are important factors in the understanding of their

Inhibition studies of three classes of Desulfovibrio hydrogenase: Application to the further characterization of the multiple hydrogenases found in Desulfovibrio vulgaris hildenborough

Autor: Guy Fauque, Paul A. Lespinat, Yves Berlier, Harry D. Peck, Eui S. Choi, Jean LeGall

Publikováno v: Biochemical and Biophysical Research Communications. 146:147-153

The three types of hydrogenase hitherto characterized in genus Desulfovibrio exhibit distinctive inhibition patterns of their proton-deuterium exchange activity by CO, NO and NO2-. The (Fe) and (NiFeSe) hydrogenases are the most sensitive to all thre

Effect of pH on H-2H exchange, H2 production and H2 uptake, catalysed by the membrane-bound hydrogenase of Paracoccus denitrificans

Autor: Michèle-France Henry, Yves Berlier, Paulette M. Vignais, Paul A. Lespinat

Publikováno v: Biochimica et Biophysica Acta (BBA) - Bioenergetics. 681:519-529

(1) The kinetics of isotope exchange catalysed by the membrane-bound hydrogenase of Paracoccus denitrificans have been studied by measuring H2H, H2 or 2H2 produced when the enzyme catalyses the exchange between 2H2 and H2O or H2 and 2H2O. (2) In the

Publikováno v: FEMS Microbiology Letters. 40:295-299

Employing membrane-inlet mass spectrometry, direct evidence is presented that substrate amounts of hydrogen are simultaneously produced and consumed during the metabolism of pyruvate plus sulfate by washed intact cells of Desulfovibrio vulgaris (Hild

Publikováno v: Journal of Industrial Microbiology. 2:15-23

Hydrogenases are among the main enzymes involved in bacterial anaerobic corrosion of metals. The study of their mode of action is important for a full comprehension of this phenomenon. The three types ofDesulfovibrio hydrogenases [(Fe), (NiFe), (NiFe
