We analyzed Clonorchis sinensis ancient DNA (aDNA) acquired from the specimens of the Joseon mummies. The target regions were cytochrome C oxidase subunit 1 (CO1), internal transcribed spacer 1 (ITS1), nicotinamide adenine dinucleotide hydrogen (NADH

Reduced coenzyme F 420 (F 420 H 2 ) is an essential intermediate in methanogenesis from CO 2 . During methanogenesis from H 2 and CO 2 , F 420 H 2 is provided by the action of F 420 -reducing hydrogenases. However, an alternative pathway has been pro

The mechanism of direct electrochemical reduction of NAD+ into NADH catalysed by Alcaligenes eutrophus H16 hydrogenase was analysed in thin layer electrochemical cells with platinum and carbon electrodes. Two phases can be distinguished in the cataly

NADH:ferredoxin reductase (EC 1.18.1.3) and NAD-reducing hydrogenase (EC 1.12.1.2) activities were detected in the cytoplasm of Hydrogenobacter thermophilus TK-6. NADH:ferredoxin reductase activity was detected using metronidazole, an artificial elec

Sequence data had indicated that cyanobacteria might possess a bidirectional hydrogenase with properties similar to the soluble enzymes from Alcaligenes eutrophus, Nocardia opaca and Desulfovibrio fructosovorans. The present study shows that extracts

The present study reports the effect of 2,4-d, quinalphos, monocrotophos, captan and carbendazim on the hydrogen metabolism (nitrogenase, photoproduction of hydrogen and hydrogenase activities) of two purple non-sulfur bacteria isolated from paddy so

Hydrogenase from Alcaligenes eutrophus H16 (E.C. 1.12.1.2) catalyzes the electrochemical reduction of the pyridine cofactor NAD + . Previous studies emphasized the kinetics and thermodynamics of the reaction. We applied hydrogenase to regenerate NADH

The regeneration of the pyridine coenzyme NADH is the key step in numerous enzymatic synthesis processes. This work deals with the kinetics of the catalysis by the Alcaligenes eutrophus H16 hydrogenase of the electrochemical reduction of NAD+ on a pl

The hydrogenase (Hyd) isolated from the cytoplasmic membrane of Wolinella succinogenes consists of three polypeptides (HydA, HydB and HydC) and contains cytochrome b (6.4 μmol/g protein), which was reduced upon the addition of H2. The enzyme catalyz

Formate hydrogenlyase (FHL) activity was induced in a strain of Escherichia coli S13 during anaerobic growth in yeast extract-tryptone medium containing 100 mM formate. The cells obtained at the optimum growth phase were immobilized in 2.5% (w/v) aga
