Increase of reactive oxygen species by desferrioxamine during experimental Chagas' disease. [PDF]
Oxidative stress is common in inflammatory processes associated with many diseases including Chagas' disease. The aim of the present study was to evaluate, in a murine model, biomarkers of oxidative stress together with components of the antioxidant ...

Redirecting Intermediary Metabolism to Counteract Cyanide Poisoning
Cyanide is coined “the classic metabolic poison”; however, FDA‐approved cyanide chelators do not counteract cyanide's metabolic damage. Here, we review the mechanisms of cyanide toxicity, with a focus on intermediary metabolism. We present the theory that, within the innate plasticity of the metabolome, there may reside metabolic pathways that can ...

Superoxide reductase from Desulfoarculus baarsii [PDF]
Superoxide radical (O2.-) is the univalent reduction product of molecular oxygen and belongs to the group of the so-called toxic oxygen derivatives. For years the only enzymatic system known to catalyze the elimination of superoxide was the superoxide dismutase (SOD), which catalyzes dismutation of superoxide radical anions to hydrogen peroxide and ...

Nitrogen Oxyanion-dependent Dissociation of a Two-component Complex That Regulates Bacterial Nitrate Assimilation [PDF]
Nitrogen is an essential nutrient for growth and is readily available to microbes in many environments in the form of ammonium and nitrate. Both ions are of environmental significance due to sustained use of inorganic fertilizers on agricultural soils ...

In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

A QM/MM Study of Nitrite Binding Modes in a Three-Domain Heme-Cu Nitrite Reductase
Copper-containing nitrite reductases (CuNiRs) play a key role in the global nitrogen cycle by reducing nitrite (NO2−) to nitric oxide, a reaction that involves one electron and two protons.

Pseudomonas chloritidismutans sp. nov., a non-denitrifying chlorate-reducing bacterium [PDF]
A Gram-negative, facultatively anaerobic, rod-shaped, dissimilatory chlorate-reducing bacterium, strain AW-1(T), was isolated from biomass of an anaerobic chlorate-reducing bioreactor.

Ferredoxin-dependent nitrite reductase of spinach has been further characterized and the relationship between this enzyme and methyl viologen-dependent nitrite reductase studied. Purified ferredoxin nitrite reductase, having a molecular weight of 86, 000, showed 2.5 times higher ferredoxin-dependent activity than methyl viologen-linked activity ...

S2 treatment regulated the flavonoid and histidine metabolism pathways of Jingu 21, reduced the protein content, increased the fat and starch contents, and decreased the peak viscosity and breakdown value. S2 treatment regulated the Stilbenoid, diarylheptanoid, and gingerol pathway of Jingu 40, and S3 treatment activated the tyrosine metabolic pathway ...
