Reduction of sulfenic acids by ascorbate in proteins, connecting thiol-dependent to alternative redox pathways
(2020-08-20)
Sulfenic acids are the primary product of thiol oxidation by hydrogen peroxide and other oxidants. Several aspects of sulfenic acid formation through thiol oxidation were established recently. In contrast, the reduction ...

Kinetic Characterization of Sulfenic Acid Reduction in 1-Cys Peroxiredoxins by Ascorbate
(Society for Free Radical Biology and MedicineFoz do Iguaçu, 2014)
Peroxiredoxins (Prxs) are Cys-based peroxidases with
remarkable catalytic efficiency that can be divided into 1-Cys or 2-
Cys, depending on the number of Cys residues involved in
catalysis. Initially, reduction of Prx ...

As reações de transferência de elétrons impulsionadas pela luz na fotossíntese usualmente envolvem um complexo clorofila-proteína presente na membrana tilacóide, que apresentam várias aplicabilidades em processos ...
The effects of fluoride based fire-fighting foams on soil microbiota activity and plant growth during natural attenuation of perfluorinated compounds
(2017-03-01)
The use of fluoride based foams increases the effectiveness of fire-fighting operations, but they are also accompanied by major drawbacks regarding environmental safety of perfluorinated compounds (PFCs). The main concern ...
Effects of gold nanoparticles on the photophysical and photosynthetic parameters of leaves and chloroplasts
(Royal Society of Chemistry, 2018-04)
Effects of gold nanoparticles (average diameter: 10-14 nm) on leaves and chloroplasts have been studied. Gold nanoparticles (AuNPs) quenched significantly chlorophyll fluorescence when introduced both in intact leaves and ...
Colorimetry as a petroleum toxicity and biodegradation screening technique
(2014-03-01)
Treatment of hydrocarbon-contaminated environments is still a great challenge today. Oily residues present in refinery separation systems waste or even the accumulation in the storage tanks has been an increasing issue. ...
