Functional Characterization and Structural Analysis of NADH Oxidase Mutants from Thermus thermophilus HB27: Role of Residues 166, 174, and 194 in the Catalytic Properties and Thermostability

open access: yesMicroorganisms, 2019
The Thermus thermophilus strain HB27 NADH-oxidase (Tt27-NOX) catalyzes the oxidation of nicotinamide adenine dinucleotide (NAD(P)H) by reducing molecular oxygen to hydrogen peroxide in a two-electron transfer mechanism.

D-3-Phosphoglycerate Dehydrogenase

open access: yesFrontiers in Molecular Biosciences, 2018
l-Serine is the immediate precursor of d-serine, a major agonist of the N-methyl-d-aspartate (NMDA) receptor. l-Serine is a pivotal amino acid since it serves as a precursor to a large number of essential metabolites besides d-serine.

Molecular mechanisms of the non-coenzyme action of thiamin in brain. Biochemical, structural and pathway analysis [PDF]

open access: yes, 2015
Thiamin (vitamin B1) is a pharmacological agent boosting central metabolism through the action of the coenzyme thiamin diphosphate (ThDP). However, positive effects, including improved cognition, of high thiamin doses in neurodegeneration may be ...

Short-time effects of herbicide nicosulfuron on biochemical activity of chernozem soil [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
Short-time effects of the herbicide nicosulfuron on biochemical activity of soil was investigated. Nicosulfuron rates of 0.3, 1.5 and 3.0 mg/kg of soil were tested in a laboratory on chernozem soil.

Effect of Reduced Tillage on Soil Enzyme Activity, Pests Pressure and Productivity of Organically Grown Spring Wheat Species

open access: yesAgronomy, 2023
The possibility of using reduced tillage in organic farming is poorly recognized. The study aimed to assess the impact of the tillage method (shallow tillage and plowing) on soil biochemical activity, pest pressure, and grain yield of Triticum ...
