The dependence of nitrate reductase activity on the level of soluble sugars in wheat and cucumber roots growing in the presence of simazine, in light or in darkness

Acta Societatis Botanicorum Poloniae, 2014
At concentrations of 25 and 5 µM, simazine inhibited nitrate reductase activity in wheat and cucumber roots, respectively. It also lowered the content of soluble sugars and decreased the activities of NADH malate dehydrogenase and NADP+ glucose-6 ...

Reconstructing the evolutionary history of F-420-dependent dehydrogenases [PDF]

, 2018
During the last decade the number of characterized F-420-dependent enzymes has significantly increased. Many of these deazaflavoproteins share a TIM-barrel fold and are structurally related to FMN-dependent luciferases and monooxygenases.

NADP-Dependent Isocitrate Dehydrogenase from Arabidopsis Roots Contributes in the Mechanism of Defence against the Nitro-Oxidative Stress Induced by Salinity

The Scientific World Journal, 2012
NADPH regeneration appears to be essential in the mechanism of plant defence against oxidative stress. Plants contain several NADPH-generating dehydrogenases including isocitrate dehydrogenase (NADP-ICDH), glucose-6-phosphate dehydrogenase (G6PDH), 6 ...

Determination of dehydrogenase activities involved in D-glucose oxidation in Gluconobacter and Acetobacter strains

Frontiers in Microbiology, 2016
Acetic acid bacteria (AAB) are known for rapid and incomplete oxidation of an extensively variety of alcohols and carbohydrates, resulting in the accumulation of organic acids as the final products.

Metabolic Engineering of Bacillus licheniformis for Production of Acetoin

Frontiers in Bioengineering and Biotechnology, 2020
Acetoin is a potential platform compound for a variety of chemicals. Bacillus licheniformis MW3, a thermophilic and generally regarded as safe (GRAS) microorganism, can produce 2,3-butanediol with a high concentration, yield, and productivity.

Histoenzymological localization of glycerol 3 phosphate dehydrogenase and succinate dehydrogenase in the mesencephalon of a minor carp Barilius bendelisis (Hamilton) [PDF]

Acta Ichthyologica et Piscatoria, 1988
This contribution deals with the studies on histoenzymological localization of two oxtdative enzymes, glycerol 3 phosphate dehydrogenase (G 3PD; EC 1.1.1.8) and succinate dehydrogenase (SD; EC 1.3.99:1) in the mesencephalic nuclei and fibre tracts of a ...

Thermostable chimeric PQQ glucose dehydrogenase [PDF]

FEBS Letters, 1995
The thermal stability of PQQ glucose dehydrogenases (PQQGDHs) which were chimeras with more than 95% made up of the N‐terminal region of Escherichia coli PQQGDH and the rest made up of the C‐terminal region of Acinetobacter calcoaceticus PQQGDHswas investigated. Among the chimeric PQQGDHs, E97A3 (E. coli 97% and A.

Ca2+, NAD(P)H and membrane potential changes in pancreatic beta-cells by methyl succinate: comparison with glucose

, 2007
The present study was undertaken to determine the main metabolic secretory signals generated by the mitochondrial substrate MeS (methyl succinate) compared with glucose in mouse and rat islets and to understand the differences.

Stability‐increasing mutants of glucose dehydrogenase

FEBS Letters, 1989
Four stability‐increasing mutants of glucose dehydrogenase from Bacillus megateriun were purified together with the wild‐type enzyme; each has a single amino acid change of Glu‐96 to Gly, Glu‐96 to Ala, Gln‐252 to Leu, or Tyr‐253 to Cys. These mutant enzymes are more heat resistant at pH 6.5 than the wild‐type enzyme; the replacement of Glu‐96 by Ala ...

Glucose oxidation and PQQ-dependent dehydrogenases in Gluconobacter oxydans

, 2009
Gluconobacter oxydans is famous for its rapid and incomplete oxidation of a wide range of sugars and sugar alcohols. The organism is known for its efficient oxidation of D-glucose to D-gluconate, which can be further oxidized to two different keto-D ...
