High levels of intracellular cysteine promote oxidative DNA damage by driving the fenton reaction.
Escherichia coli is generally resistant to H(2)O(2), with >75% of cells surviving a 3-min challenge with 2.5 mM H(2)O(2). However, when cells were cultured with poor sulfur sources and then exposed to cystine, they transiently exhibited a greatly increased susceptibility to H(2)O(2), with <1% surviving the challenge. Cell death was due to an unusually rapid rate of DNA damage, as indicated by t...
متن کاملControlling the fenton reaction in wine.
The fate of hydrogen peroxide in a model wine system was studied under a competitive scenario in the presence of ferrous ions and sulfur dioxide. The metal-catalyzed reduction of hydrogen peroxide (H(2)O(2)), referred to as the Fenton reaction, yields hydroxyl radicals capable of oxidizing ethanol to acetaldehyde and is now thought to be a key step in nonenzymatic wine oxidation. It appears tha...
متن کاملA Trypanosoma brucei Kinesin Heavy Chain Promotes Parasite Growth by Triggering Host Arginase Activity
BACKGROUND In order to promote infection, the blood-borne parasite Trypanosoma brucei releases factors that upregulate arginase expression and activity in myeloid cells. METHODOLOGY/PRINCIPAL FINDINGS By screening a cDNA library of T. brucei with an antibody neutralizing the arginase-inducing activity of parasite released factors, we identified a Kinesin Heavy Chain isoform, termed TbKHC1, as...
متن کاملFenton reaction facilitates organic nitrogen acquisition by an ectomycorrhizal fungus
Boreal trees rely on their ectomycorrhizal fungal symbionts to acquire growth-limiting nutrients, such as nitrogen (N), which mainly occurs as proteins complexed in soil organic matter (SOM). The mechanisms for liberating this N are unclear as ectomycorrhizal fungi have lost many genes encoding lignocellulose-degrading enzymes present in their saprotrophic ancestors. We hypothesized that hydrox...
متن کاملEnhanced degradation of gaseous benzene by a Fenton reaction
A wet scrubbing process coupled with advanced oxidation processes (AOP) has raised great interest for the abatement of volatile organic compounds (VOCs) owing to its strong oxidation capacity and few byproducts. Fenton as an AOP has been widely used in wastewater treatment. However, the dosing method of Fenton reagents is not suitable for the treatment of continuous-flow VOCs waste-gas since H2...
