Example sentences for: arsenite
How can you use “arsenite” in a sentence? Here are some example sentences to help you improve your vocabulary:
The arsC gene is of particular interest in that its product, the soluble enzyme arsenate reductase, catalyzes the reduction of arsenate to arsenite.
Despite the suggestion of HGT and duplication events, the arsC phylogeny suggests that arsenate reductase is an evolutionarily old enzyme, a hypothesis that was recently suggested for arsenite oxidase [ 38 ] . This is the first phylogenetic analysis of an arsenic redox active gene to include all three domains and the Archaea and Bacteria were clearly separated, with S. cerevisiae subsequently branching from Archaea.
Both forms are toxic to microorganisms, with arsenite disrupting enzyme function, and arsenate behaving as a phosphate analog and interfering with phosphate uptake and utilization [ 1 ] . Microorganisms have evolved a variety of mechanisms for coping with arsenic toxicity, including minimizing the amount of arsenic that enters the cell (e.g.
through increased specificity of phosphate uptake, [ 2 ] ), arsenite oxidation through the activity of arsenite oxidase [ 3 4 ] , or peroxidation reactions with membrane lipids [ 5 6 ] . Other microorganisms utilize arsenic in metabolism, either as a terminal electron acceptor in dissimilatory arsenate respiration [ 7 8 9 10 ] or as an electron donor in chemoautotrophic arsenite oxidation [ 11 12 ] . However, the most well-characterized microbial arsenic detoxification pathway involves the ars operon [ 2 13 ] .
Inorganic arsenic exists primarily in two valence states: arsenite (As III ) and arsenate (As V , or the arsenate ion AsO 4 3-).
