Nitric oxide production by arsenite
Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2003Arsenic can either enhance or reduce nitric oxide (NO) production, depending on the type of cell, the species and dose of arsenical tested. The mechanisms of how arsenic increases or decreases NO production remain unclear. Because NO is associated with many pathological conditions, it is conceivable that in those arsenic-target tissues, the NO ...

Diversity of inorganic arsenite biotransformation
Biological Trace Element Research, 1999Biotransformation of inorganic arsenic in mammals is catalyzed by three serial enzyme activities: arsenate reductase, arsenite methyltransferase, and monomethylarsonate methyltransferase. Our laboratory has purified and characterized these enzymes in order to understand the mechanisms and elucidate the variations of the responses to arsenate/arsenite ...

The inhibition of acetylcholinesterase by arsenite and fluoride
Archives of Biochemistry and Biophysics, 1983The effect of fluoride on the rate of reaction of acetylcholinesterase with arsenite, on the rate of dissociation of the enzyme-arsenite complex, and on the equilibrium between enzyme and arsenite was studied. Fluoride decreases the rate of the reaction between acetylcholinesterase and arsenite and changes the apparent equilibrium dissociation constant

Beyond arsenite: Arsenite-oxidizing prokaryotes drive sulfur compound oxidation
Bioresource TechnologyArsenite oxidation prokaryotes (AsOPs) contribute significantly to the biogeochemical processes governing arsenic cycling. Since AsOPs can oxidize AsIII to AsV, markedly reducing arsenic toxicity and decreasing its migration potential, they have been widely utilized in the restoration of AsIII-affected sites and in the design of bioreactors for ...

Arsenite and arsenate levels in wine
Bulletin of Environmental Contamination and Toxicology, 1977Arsenic is receiving renewed attention because it is released to the atmosphere by coal-fired power plants as well as by smelters and agricultural pesticides. A portion of this arsenic that accumulates on agricultural land may be taken up by plants, animals, and ultimately by man.

Arsenite methyltransferase—a unitasking arsenite methylator or a hidden protein moonlighter?
Background: Inorganic arsenic is metabolised by arsenic 3-methyltransferase (AS3MT) to form methylated arsenic species that are excreted more rapidly. AS3MT was suspected to have an additional function in view of its unexplained evolutionary conservation together with the stress response and slower proliferation exhibited basally by As3mt knockout ...openaire +1 more source
