Arsenates
Inorganic or organic salts and esters of arsenic acid.
Arsenate Reductases
Oxidoreductases that specifically reduce arsenate ion to arsenite ion. Reduction of arsenate is a critical step for its biotransformation into a form that can be transported by ARSENITE TRANSPORTING ATPASES or complexed by specific sulfhydryl-containing proteins for the purpose of detoxification (METABOLIC DETOXIFICATION, DRUG). Arsenate reductases require reducing equivalents such as GLUTAREDOXIN or AZURIN.
Ion Pumps
A general class of integral membrane proteins that transport ions across a membrane against an electrochemical gradient.
Arsenite Transporting ATPases
Efflux pumps that use the energy of ATP hydrolysis to pump arsenite across a membrane. They are primarily found in prokaryotic organisms, where they play a role in protection against excess intracellular levels of arsenite ions.

Probing the function of the conserved tryptophan in the flexible loop of the Yersinia protein-tyrosine phosphatase. (1/405)

The involvement of the strictly conserved Trp354 residue in the catalysis of the Yersinia protein tyrosine phosphatase (PTPase) has been investigated by site-directed mutagenesis and kinetic studies. Crystallographic structural data have revealed that Trp354 interacts with the active site Arg409 and is located at one of the hinge positions of the flexible surface loop (WpD loop) which also harbors the general acid/base (Asp356) essential for catalysis [Schubert, H. L., Fauman, E. B., Stuckey, J. A., Dixon, J. E. & Saper, M. A. (1995) Protein Sci. 4, 1904-1913]. Two mutants were constructed and expressed that contained the Trp354-->Phe and Trp354-->Ala substitutions. The K(m) of the W354F and W354A mutants were not significantly different from that of the wild-type. However, a major decrease in the affinity for oxyanions was observed for the mutants, which is consistent with Trp354 playing a role in aligning Arg409 for oxyanion binding. In addition replacement of Trp354 with Phe or Ala caused a decrease in kcat of 200-fold and 480-fold, respectively, and impaired the ability of the mutant enzymes to stabilize the negative charge in the leaving group at the transition state. In fact, the W354F and W354A mutants exhibited catalytic efficiency and leaving group dependency similar to those observed for the general acid-deficient PTPase D356N. These results indicate that Trp354 is an important residue that keeps the WpD loop in a catalytically competent conformation and positions the general acid/base Asp356 in the correct orientation for proton transfer.  (+info)

Sulfurospirillum barnesii sp. nov. and Sulfurospirillum arsenophilum sp. nov., new members of the Sulfurospirillum clade of the epsilon Proteobacteria. (2/405)

Enhanced transcription factor DNA binding and gene expression induced by arsenite or arsenate in renal slices. (3/405)

Although the kidney represents a target for the accumulation and toxicity of arsenic, little is known about the molecular targets of arsenic in this organ. Therefore, these studies were designed to examine the molecular impact of arsenite [As(III)] and arsenate [As(V)] at low (nanomolar) concentrations. Precision-cut rabbit renal cortical slices were challenged with As(III) or As(V) for up to 8 h. Neither form of the metal induced overt cytotoxicity as assessed by intracellular K+ levels over this time period at concentrations from 0.01-10 microM. In addition, no alterations in the expression of Hsp 60, 70, or 90 were observed. However, induction of heme oxygenase-1 (Hsp 32) was seen following a 4-h challenge with As(III), but not with As(V). As(III) and As(V) induced DNA binding of AP-1 at 2- and 4-h exposure; following a 6-h exposure there was no difference. Although no alteration in the DNA binding activity of ATF-2 was induced by As(III) or As(V), both forms enhanced the DNA binding activity of Elk-1. Enhanced DNA binding activity of AP-1 and Elk-1 correlated with increased gene expression of c-fos, but not c-jun, at 2 h. c-myc gene expression was also induced by As(III) and As(V), albeit at a later time point (6 h). These results suggest that acute arsenic challenge, by either As(III) or As(V), is associated with discrete alterations in the activity of signaling pathways and gene expression in renal tissue.  (+info)

N-acetylneuraminic acid transport by Streptococcus oralis strain AR3. (4/405)

Streptococcus oralis has emerged as one of the most important organisms of the viridans streptococcus group in terms of infections and is recognised as an agent of infective endocarditis and, in immunocompromised patients, septicaemia. The mechanisms by which this organism proliferates in vivo are unknown. However, host-derived sialic acids -- including N-acetylneuraminic acid (NeuNAc) which is present in serum and cell-associated glycoproteins -- are a potential source of fermentable carbohydrate for bacterial proliferation, especially for sialidase-producing bacteria, including S. oralis. To further elucidate the role of NeuNAc in supporting growth, this study determined the ability of S. oralis strain AR3 (isolated from a patient with infective endocarditis) to transport NeuNAc and characterised the transport system. The transport of [14C]-labelled NeuNAc into S. oralis was monitored and this transport system was induced by growth of the bacteria in the presence of the N-acetylated sugars NeuNAc, N-acetylglucosamine and N-acetylmannosamine. The transport system followed typical Michaelis-Menten kinetics, with a Km of 21.0 microM and a Vmax of 2.65 nmoles of NeuNAc transported/min/mg of dry cell mass. NeuNAc transport was inhibited by the presence of exogenous N-glycolylneuraminic acid, a related sialic acid. Chlorhexidine, NaF and 2,4-dinitrophenol were potent inhibitors of the transport system, suggesting that the uptake of NeuNAc occurs via a proton motive force-dependent permease system. This is the first report of the mechanism by which NeuNAc transport occurs in pathogenic streptococci. This transport process may have relevance to the acquisition of a source of fermentable carbohydrate and thus bacterial proliferation in vivo.  (+info)

Sodium arsenate induces overproduction of interleukin-1alpha in murine keratinocytes: role of mitochondria. (5/405)

It has recently been demonstrated that arsenic induces overexpression of keratinocyte-derived growth factors, which are likely to have a significant role in arsenic-induced skin hyperkeratoses and cancer. The mechanism(s) involved in this induction are, however, still elusive. The purpose of this study was to investigate the early intracellular events that follow in vitro treatment with sodium arsenate in a murine keratinocyte cell line (HEL30), which leads to cytokine overproduction. First, we observed that sodium arsenate induced a concentration-dependent production of interleukin-1alpha and a significant increase in cell proliferation, that could be suppressed by the addition of a neutralizing antibody against murine interleukin-1alpha, confirming the ability of arsenic to induce keratinocyte growth-promoting cytokines. Electron microscopic analysis revealed that arsenate induced a dramatic alteration in keratinocyte mitochondria. This effect could be prevented by rotenone pretreatment, which suggests the possible involvement of mitochondria-derived reactive oxygen species. Arsenic induced a concentration- and time-dependent increase in cellular oxidative activity, which was followed by activation of redox-sensitive transcription factors such as nuclear factor-kappaB and activator protein-1, that are essential for interleukin-1alpha synthesis. Prior treatment with rotenone or prolonged treatment with ethidium bromide, an inhibitor of mitochondrial DNA and RNA synthesis, to deplete cells of functional mitochondria, completely prevented sodium arsenate-induced interleukin-1alpha production, this indicates the pivotal role of these organelles in sodium arsenate-induced keratinocyte growth factors.  (+info)

Reactivity of glutaredoxins 1, 2, and 3 from Escherichia coli shows that glutaredoxin 2 is the primary hydrogen donor to ArsC-catalyzed arsenate reduction. (6/405)

In Escherichia coli ArsC catalyzes the reduction of arsenate to arsenite using GSH with glutaredoxin as electron donors. E. coli has three glutaredoxins: 1, 2, and 3, each with a classical -Cys-Pro-Tyr-Cys- active site. Glutaredoxin 2 is the major glutathione disulfide oxidoreductase in E. coli, but its function remains unknown. In this report glutaredoxin 2 is shown to be the most effective hydrogen donor for the reduction of arsenate by ArsC. Analysis of single or double cysteine-to-serine substitutions in the active site of the three glutaredoxins indicated that only the N-terminal cysteine residue is essential for activity. This suggests that, during the catalytic cycle, ArsC forms a mixed disulfide with GSH before being reduced by glutaredoxin to regenerate the active ArsC reductase.  (+info)

Signal transduction pathways regulated by arsenate and arsenite. (7/405)

Arsenate and arsenite activate c-Jun N-terminal kinase (JNK), however, the mechanism by which this occurs is not known. By expressing inhibitory mutant small GTP-binding proteins, p21-activated kinase (PAK) and mitogen-activated protein kinase/extracellular signal-regulated kinase kinase kinases (MEKKs), we have identified specific proteins that are involved in arsenate- and arsenite-mediated activation of JNK. We observe a distinct difference between arsenate and arsenite signaling, which demonstrates that arsenate and arsenite are capable of activating unique proteins. Both arsenate and arsenite activation of JNK requires Rac and Rho. Neither arsenate nor arsenite signaling was inhibited by a dominant-negative mutant of Cdc42 or Ras. Arsenite stimulation of JNK requires PAK, whereas arsenate-mediated activation of JNK was unaffected by inhibitory mutant PAK. Of the four MEKKs tested, only MEKK3 and MEKK4 are involved in arsenate-mediated activation of JNK. In contrast, arsenite-mediated JNK activation requires MEKK2, MEKK3 and MEKK4. These results better define the mechanisms by which arsenate and arsenite activate JNK and demonstrate differences in the regulation of signal transduction pathways by these inorganic arsenic species.  (+info)

Interactions of arsenate, sulfate and phosphate with yeast mitochondria. (8/405)

In the presence of K(+), addition of ATP or ethanol to yeast mitochondria triggers the depletion of the transmembrane potential (DeltaPsi) and this is prevented by millimolar concentrations of phosphate (PO(4)). Different monovalent and polyvalent anions were tested for their protective effects on mitochondria from Saccharomyces cerevisiae. Only arsenate (AsO(4)) and sulfate (SO(4)) were as efficient as PO(4) to protect mitochondria against the K(+) mediated swelling, depletion of the DeltaPsi, and decrease in the ratio of uncoupled state to state 4 respiration rates. Protection by PO(4), SO(4) or AsO(4) was inhibited by mersalyl, suggesting that these anions interact with a site located in the matrix side. In addition, the effects of SO(4) and AsO(4) on the F(1)F(0)-ATPase were tested: both SO(4) and AsO(4) inhibited the synthesis of ATP following competitive kinetics against PO(4) and non-competitive kinetics against ADP. The mersalyl sensitive uptake of (32)PO(4) was not inhibited by SO(4) or AsO(4), suggesting that the synthesis of ATP was inhibited at the F(1)F(0)-ATPase. The hydrolysis of ATP was not inhibited, only a stimulation was observed when AsO(4) or sulfite (SO(3)) were added. It is suggested that the structure and charge similarities of PO(4), AsO(4) and SO(4) result in undiscriminated binding to at least two sites located in the mitochondrial matrix: at one site, occupation by any of these three anions results in protection against uncoupling by K(+); at the second site, in the F(1)F(0)-ATPase, AsO(4) and SO(4) compete for binding against PO(4) leading to inhibition of the synthesis of ATP.  (+info)

Natural pollution of groundwater by arsenic adversely affects the health of tens of millions of people worldwide, with the deltaic aquifers of SE Asia being particularly polluted. The pollution is caused primarily by, or as a side reaction of, the microbial reduction of sedimentary Fe(III)-oxyhydroxides, but the organism(s) responsible for As release have not been isolated. Here we report the first isolation of a dissimilatory arsenate reducer from sediments of the Bengal Basin in West Bengal. The bacterium, here designated WB3, respires soluble arsenate and couples its reduction to the oxidation of acetate; WB3 is therefore implicated in the process of arsenic pollution of groundwater, which is largely by arsenite. The bacterium WB3 is also capable of reducing dissolved Fe(III) citrate, solid Fe(III)-oxyhydroxide, and elemental sulfur, using acetate as the electron donor. It is a member of the Desulfuromonas genus and possesses a dissimilatory arsenate reductase that was identified using ...

MIXITE (Hydrated Bismuth Copper Arsenate Hydroxide)
to name a couple. Mixite is probably the best known of these, but is still a rare mineral by most considerations. It forms in the oxidation zone of metal ores that probably contained primary bismuth sulfides such as emplectite. As a mineral collection specimen, mixite is truly a wonderful addition. It forms nice radial clusters called spherules, made up of fine acicular crystals. The color is typically a brilliant green of one shade or another coupled with an attractive silky luster. Mixite lends its name to a small group of rather obscure minerals called the Mixite Group. The Mixite Group is a group of hexagonal, hydrated copper arsenate and phosphate hydroxides with a general formula of ACu6(XO4)3(OH)6 - 3H2O The A in the formula can be either bismuth, aluminum, calcium, cerium, lanthanum, yttrium, neodymium or thorium. The X can be either arsenic or phosphorous. These are the members of the Mixite Group: ...

Beyond Pesticides, January 4, 2011) A report released by the Environmental Working Group (EWG) finds that drinking water in 31 cities across the country is contaminated with hexavalent chromium, or chromium-6, a carcinogenic chemical contaminant with numerous sources including treated wood utility poles that line streets and backyards across the the United States. Wood treated with chromated copper arsenate (CCA), such as playgrounds, decks, and railroad ties, in addition to utility poles, can leach the chemicals into soils and groundwater, creating serious risks to public health. Other common sources of chromium-6 pollution include discharge from steel and pulp mills as well as metal-plating and leather-tanning facilities. It can also pollute water through erosion of natural deposits.. The use of CCA in the treatment of utility poles is notable not only because of the presence of poles in numerous communities throughout the country, but also because utility companies often donate or sell ...

ACQ stands for Alkaline Copper Quat. The main active ingredient is copper, which was the main active ingredient in CCA chromated copper arsenate pressure treatment, which was phased out in 2003. Though the copper remains the same, the other ingredients in ACQ are much less toxic than the chromium and arsenic that were used in CCA. According to manufacturers literature on ACQ, quat acts as a co-biocide, providing additional protection from fungi and insect attack that copper alone would not control. Quats are commonly used in household disinfectants and cleaners, and in swimming pools and spas. Quats are biodegradable in soil. Recently my husband and I were faced with a decision as to whether or not we would use ACQ treated wood for posts to hold a garden gate.

Pueraria tuberose Linn. is an inexpensive and efficient source to provide all the required nutrients and medicinal benefits for a healthy and rejuvenating body. The present investigation has been undertaken to evaluate the role of Pueraria tuberosa Linn. in modifying the sodium arsenate induced biochemical alterations in albino rats. Administration of sodium arsenate in rats induces oxidative stress, which leads to the generation of free radicals in the body. These free radicals interact with tissue leading to tissue damage i.e, kidney damage. Animals were divided into 6 groups, Group I (control group) rats were treated with normal saline (1mg/kg), Group II ( Positive Control) rats were treated with sodium arsenate (1mg/kg).Group III rats were treated with sodium arsenate (1mg/kg) and Vitamin E (100 mg/kg).Group IV rats were treated with sodium arsenate (1mg/kg) and Pueraria tuberosa linn. extract (50 mg/kg), Group V rats were treated with sodium arsenate (1mg/kg) and Pueraria tuberosa linn.

Physical, Chemical, and Biological Methods for the Removal of Arsenic CompoundsPhysical, Chemical, and Biological Methods for the Removal of Arsenic Compounds
Arsenic is a toxic metalloid which is widely distributed in nature. It is normally present as arsenate under oxic conditions while arsenite is predominant under reducing condition. The major discharges of arsenic in the environment are mainly due to natural sources such as aquifers and anthropogenic sources. It is known that arsenite salts are more toxic than arsenate as it binds with vicinal thiols in pyruvate dehydrogenase while arsenate inhibits the oxidative phosphorylation process. The common mechanisms for arsenic detoxification are uptaken by phosphate transporters, aquaglyceroporins, and active extrusion system and reduced by arsenate reductases via dissimilatory reduction mechanism. Some species of autotrophic and heterotrophic microorganisms use arsenic oxyanions for their regeneration of energy. Certain species of microorganisms are able to use arsenate as their nutrient in respiratory process. Detoxification operons are a common form of arsenic resistance in microorganisms. Hence, the use of

Ive found something new to blame all my troubles on. Failing memory. Gray hair. Weight gain. Fatigue. Poor eyesight. Lack of muscle tone. The culprit could be chromated copper arsenate. Say that fast three times. I dont mean to make light of what is a serious health concern. But until I read Times staff writer Julie Hausermans investigative report March 11, I didnt even know it existed. Now, it turns out, I and untold others may have been poisoned by chemically treated wood, the kind many of us use to build the decks, fences and doghouses in our back yards. Even though manufacturers and the federal government have known for decades that the treated wood poses a risk to those who touch it, and that it can leach poisonous arsenic into the ground, the word hasnt trickled down to the masses of folks who buy the stuff. Clearly printed warnings might have accomplished that, but the government -- specifically the Environmental Protection Agency -- delegated that responsibility to the people who ...

Long-term stake evaluations of waterborne copper systems | TreesearchLong-term stake evaluations of waterborne copper systems | Treesearch
Limitations on the use of chromated copper arsenate (CCA) have heightened interest in use of arsenic-free copper-based alternatives. For decades, the USDA Forest Products Laboratory has been evaluating several of these systems in stake plots. Southern Pine 38- by 89- by 457-mm (1.5- by 3.5- by 18-inch) stakes were treated with varying concentrations of acid copper chromate (ACC), ammoniacal copper borate (ACB), or acid copper formate (CF) and buried to one-half their length in plots within the Harrison Experimental Forest in Mississippi. Stakes treated with acidic formulations (ACC and CF) generally performed well at copper oxide retentions above 1.8 kg/m3 (0.11 lb/ft3), as did ACB-treated stakes containing 3.5 kg/m3 (0.22 lb/ft 3 ) CuO. However, even at retentions where median ratings and the average index of condition remained high for over 20 years, individual stakes occasionally failed in less than 10 years. The results suggest that occasional early failures caused by copper-tolerant fungi ...

Mesoporous pellet adsorbent developed from mixing at an appropriate ratio of natural clay, iron oxide, iron powder, and rice bran was used to investigate the optimization process of batch adsorption parameters for treating aqueous solution coexisting with arsenate and arsenite. Central composite design under response surface methodology was applied for optimizing and observing both individual and interactive effects of four main influential adsorption factors such as contact time (24-72 h), initial solution pH (3-11), adsorbent dosage (0-20 g/L) and initial adsorbate concentration (0.25-4.25 mg/L). Analysis of variance suggested that experimental data were better fitted by the quadratic model with the values of regression coefficient and adjusted regression coefficient higher than 95%. The model accuracy was supported by the correlation plot of actual and predicted adsorption efficiency data and the residual plots. The Pareto analysis suggested that initial solution pH, initial adsorbate concentration,

Ars operon - WikipediaArs operon - Wikipedia
In molecular biology, the ars operon is an operon found in several bacterial taxon. It is required for the detoxification of arsenate, arsenite, and antimonite. This system transports arsenite and antimonite out of the cell. The pump is composed of two polypeptides, the products of the arsA and arsB genes. This two-subunit enzyme produces resistance to arsenite and antimonite. Arsenate, however, must first be reduced to arsenite before it is extruded. A third gene, arsC, expands the substrate specificity to allow for arsenate pumping and resistance. ArsC is an approximately 150-residue arsenate reductase that uses reduced glutathione (GSH) to convert arsenate to arsenite with a redox active cysteine residue in the active site. ArsC forms an active quaternary complex with GSH, arsenate, and glutaredoxin 1 (Grx1). The three ligands must be present simultaneously for reduction to occur. ArsA and ArsB form an anion-translocating ATPase. The ArsB protein is distinguished by its overall hydrophobic ...

Arsenic in Play Structures - Center for Environmental Health | Center for Environmental HealthArsenic in Play Structures - Center for Environmental Health | Center for Environmental Health
Problem: Until the early 2000s, most of the pressure-treated wood used in the United States for outdoor structures such as playground equipment, picnic tables, benches and decks was treated with the preservative, Chromated Copper Arsenate (CCA). This chemical was the primary preservative used in the pressure-treating process to protect wood against weather, mold and insects. Studies show that CCA-treated wood is continually leaching (releasing) arsenic to the surface of the wood. Arsenic is known to cause cancer in humans: it is a potent skin, bladder and lung carcinogen. Arsenic is also linked to liver and kidney cancer, immune system suppression, increased risk of high blood pressure, cardiovascular disease, endocrine disruption (altering normal hormone levels or activity in the body) and diabetes. Studies have confirmed that high levels of arsenic can be released onto childrens hands by direct contact with arsenic-treated wood. Young children, in particular, are at risk of ingesting ...

PANNA: Arsenic Risk in Childrens Playground Equipment | Pesticide Action NetworkPANNA: Arsenic Risk in Childrens Playground Equipment | Pesticide Action Network
Children are more likely to be exposed to harmful levels of arsenic from play structures, picnic tables and decks than from drinking water according to a recent Environmental Working Group (EWG) study. We know that arsenic in drinking water is dangerous for kids, but what we found was that the arsenic in lumber is an even greater risk, said EWG analyst Renee Sharp. In less than ten days, an average five year old playing on an arsenic-treated playset would exceed the lifetime cancer risk considered acceptable under federal pesticide law. The report, entitled Poisoned Playgrounds, is based on analysis of data from 180 samples of treated wood taken across the U.S. and an extensive review of scientific literature.. Virtually all of the lumber sold for outdoor use in the U.S. is pressure-treated and injected with toxins that act as preservatives and pesticides. Chromated copper arsenate (CCA) is the most common wood preservative used in the U.S., containing 22% pure arsenic. Arsenic is an acute ...

Bosworth Urges Utility Pole Changes | Great Neck RecordBosworth Urges Utility Pole Changes | Great Neck Record
Town of North Hempstead Supervisor Judi Bosworth is continuing to urge PSEG Long Island to use nontoxic preservatives on its utility poles, after it was reported this week that the utility company would start transitioning away from using the controversial preservative pentachlorophenol (penta) and towards using a different one called CCA, or Chromated Copper Arsenate. Penta and CCA are both restricted-use pesticides and are approved by the EPA for utility poles. CCA contains known carcinogens when inhaled or ingested.. It seems that PSEG is just exchanging one poison for another, said Bosworth. Simply trading penta for CCA doesnt make sense or address the issue. I will continue to urge our utility companies to use non-toxic treatments for wooden poles or to begin using composite poles or another safe alternative.. In a letter to PSEG-LI President and CEO David Daly, Bosworth stated: Cost-saving measures that put citizens health at risk are short sighted. With PSEG-LI setting about 4,000 ...

Superior removal of arsenic from water with zirconium metal-organic framework UiO-66 - ScienceOpenSuperior removal of arsenic from water with zirconium metal-organic framework UiO-66 - ScienceOpen
In this study, water stable zirconium metal-organic framework (UiO-66) has been synthesized and for the first time applied as an adsorbent to remove aquatic arsenic contamination. The as-synthesized UiO-66 adsorbent functions excellently across a broad pH range of 1 to 10, and achieves a remarkable arsenate uptake capacity of 303 mg/g at the optimal pH, i.e., pH = 2. To the best of our knowledge, this is the highest arsenate As(V) adsorption capacity ever reported, much higher than that of currently available adsorbents (5-280 mg/g, generally less than 100 mg/g). The superior arsenic uptake performance of UiO-66 adsorbent could be attributed to the highly porous crystalline structure containing zirconium oxide clusters, which provides a large contact area and plenty of active sites in unit space. Two binding sites within the adsorbent framework are proposed for arsenic species, i.e., hydroxyl group and benzenedicarboxylate ligand. At equilibrium, seven equivalent arsenic species can be captured by

The arsenic speciation and arsenic removal in chitosan packed column were studied. Arsenic removal experiments were carried out with an arsenic standard solution (1.0 mg/l) and drilled well water samples from Limon Mine Community at different pH, water flowrate, and volume of adsorbent material. The simulation of arsenic speciation was carried out at a pH range from 0 to 12, a temperature of 25ºC, a pE equal to 4, and a total arsenic concentration of 1.34 x 10-5 mol kg-1. According to speciation calculations arsenic is found mainly in oxidized form in the conditions of Limon Mines drilled well waters, dihydrogen arsenate ion (H2AsO4-), and hydrogen arsenate ion (HAsO42-) being the major species. The experiments showed that arsenic adsorption depends mainly on the pH as well as the activity of functional groups that compose the chitosan structure. At pH 3 and volume of adsorbent material of 337.8 cm3 an adsorption of 94% was obtained from arsenic standard solution, and the arsenic present in ...

The Curious Wavefunction: Arsenic DNA, chemistry and the problem of differing standards of proof in cross-disciplinary scienceThe Curious Wavefunction: Arsenic DNA, chemistry and the problem of differing standards of proof in cross-disciplinary science
The article explains why it was that standards of proof that were acceptable to different degrees to geologists, physicists and biologists were unacceptable to chemists. The answer pertains to what we call background knowledge. In this case, chemists were compelled to ask how DNA with arsenic replacing phosphorus in its backbone could possibly be stable given everything they knew about the instability of arsenate esters. The latter had been studied for several decades, and while arsenic DNA itself had not been synthesized before, simpler arsenate esters were known to be highly unstable in water. The chemists were quite confident in extrapolating from these simple cases to questioning the stable existence of arsenic DNA; if arsenic DNA indeed were so stable, then almost everything they had known about arsenate esters for fifty years would have been wrong, a possibility that was highly unlikely. Thus for chemists, arsenic DNA was an extraordinary claim. And as Carl Sagan said, they needed to see ...

Vegetable garden containers - Knowledgebase Question - Garden.orgVegetable garden containers - Knowledgebase Question - Garden.org
Pressure treated lumber is treated with chromium copper arsenate (CCA) to prolong the life of the wood. Its always best to wear gloves when handling, and wear a dust-mask while youre cutting the timbers. As far as safety is concerned when used around vegetables, there are two sides to the story. One says they are safe, citing studies showing little or no leaching of arsenate. The other side has its own studies and says it does leach at dangerous levels. I prefer to err on the cautious side and recommend gardeners not use pressure treated wood around food plants. Try cedar, redwood, plastic timbers, or even cement blocks instead. If you already have the pressure treated wood in place, you can line it with heavy plastic to keep chemicals from leaching into the bed and you can be careful to plant only above ground veggies (tomatoes, corn, etc.) nearest the edges of the bed, saving the center for underground veggies such as beets and carrots ...

SMART: HTH ARSR domain annotationSMART: HTH ARSR domain annotation
The arsR-type HTH domain is a DNA-binding, winged helix-turn-helix (wHTH) domain present in transcription regulators of the arsR/smtB family, involved in stress-response to heavy metal ions. This family of prokaryotic metal-sensing transcription repressors is named after Escherichia coli arsR, an arsenic-responsive repressor of the ars operon for arsenate reductase and metal ion extrusion, and after Synechococcus PCC 7942 smtB, a Zn(II)-responsive repressor of the smtA gene for a Zn sequestering metallothionein [ (PUBMED:12829264) ]. ArsR/smtB-like repressors of metal resistance operons specifically bind to the operator/promoter and seem to dissociate from the DNA in the presence of metal ions, permitting transcription of proteins involved in metal-ions efflux and/or detoxification. The crystal structure of the cyanobacterial smtB shows a fold of five alpha-helices (H) and a pair of antiparallel beta-strands (B) in the topology H1-H2-H3-H4-B1-B2-H5. Helices 3 and 4 comprise the helix-turn-helix ...

Microbes involved in arsenic mobilization and respiration: a review on isolation, identification, isolates and implicationsMicrobes involved in arsenic mobilization and respiration: a review on isolation, identification, isolates and implications
Microorganisms play an important role in arsenic (As) cycling in the environment. Microbes mobilize As directly or indirectly, and natural/geochemical processes such as sulphate and iron reduction, oxidative sulphide mineral dissolution, arsenite (AsO33?) oxidation and arsenate (AsO43?) respiration further aid in As cycle in the environment. Arsenate serves as an electron donor for the microbes during anaerobic conditions in the sediment. The present work reviews the recent development in As contamination, various As-metabolizing microbes and their phylogenetic diversity, to understand the role of microbial communities in As respiration and mobilization.

More than 500 tufa spires rise up from the basin of the ancient Searles Lake bed 10-miles south of Trona, a depressed mining town. Similar to Mono Lake, these tufa towers formed underwater as calcium carbonate precipitated out of the water over time, only to be exposed later as the lake bed dried up. The towers range in age from 10,000 - 100,000 years old.

RRResearch: Yet another reason why the Wolfe-Simon conclusion is so improbableRRResearch: Yet another reason why the Wolfe-Simon conclusion is so improbable
The covalent radius of arsenic is about 11% larger than that of phosphorus (see this periodic table tool), and the As-O bond lengths reported in Table 3 are about 13% longer than the P-O bond lengths in DNA (Table S3). No DNA polymerase could function on a template with such unpredictable geometry. Even if it could bind to the template strand and proceed along it, the differing bond lengths it encountered would prevent the incoming nucleotides from forming the necessary bond with the growing end. And even if it could create the backbone of the daughter strand, the error rate due to base mispairing would be so high that reproduction would fail ...

Control Creeping Oxalis - Treatment | Searles GardeningControl Creeping Oxalis - Treatment | Searles Gardening
What does Creeping Oxalis look like and how to control it? Another member of the large family of oxalis species, this form differs from the others in that it does not produce underground bulbs and spreads rapidly by means of stolons that simply root into the surrounding soil. It spreads quickly not only by stolons, but also by explosive seed dispersal enabling it to colonise

Sooty blotch and flyspeck may be as old as apples themselves. Drawings of apple varieties from the 1820s clearly show sooty blotch on every fruit. It wasnt until sprayed-on pesticides, such as lime sulfur and lead arsenate, became popular around 1900 that consumers began to expect to buy apples without a heavy coating of sooty blotch and flyspeck. The cosmetically perfect apples found in todays supermarkets werent common until the middle of the 20th century, when more effective organic fungicides appeared.. ...

Arsenic9
  • Calcium salt (2:3) of arsenic acid, Cucumber dust, Tricalcium arsenate, Tricalcium ortho-arsenate [Note: Also see specific listing for Arsenic (inorganic compounds, as As). (cdc.gov)
  • Arsenic-sulfide minerals (ASM) are formed during microbial reduction of arsenate (As V ) and sulfate (SO 4 2- ). (njit.edu)
  • The second focused on children's aggregate exposures to arsenic and chromium from chromated copper arsenate (CCA)-treated playsets and decks, using a scenario-specific version of SHEDS-Pesticides called SHEDS-Wood. (epa.gov)
  • Chromated copper arsenate (CCA) is a pesticide containing chromium, copper and arsenic that protects wood from termites, fungi and other pests. (emsl.com)
  • During a 2010 NASA news conference, Felisa Wolfe-Simon , then of NASA's Astrobiology Institute , announced GFAJ-1 was incorporating arsenate (a form of arsenic) into its DNA in place of phosphate (a compound commonly used by life). (csmonitor.com)
  • In an attempt to investigate the relationships between ARSENATE (as less soluble fraction of soil ARSENIC ) and the soils physico-chemical characteristics, eight pedons from the most polluted parts across the study area were sampled. (sid.ir)
  • Analysis of the results for the 38 soil samples revealed significant relationships between ARSENATE (considered as major less toxic fraction of soil ARSENIC ) with sand, silt, organic carbon, FREE IRON OXIDE s, nitrate, and phosphate. (sid.ir)
  • For arsenic removal, chlorine changes arsenite (AsIII) to arsenate (AsV), and iron in the water is converted to ferric hydroxide, which allows the arsenate to form ferric arsenate, which is then removed by the Pro-OX media. (cleanwaterstore.com)
  • 2020). Improving Arsenic Tolerance of Pyrococcus furiosus by Heterologous Expression of a Respiratory Arsenate Reductase . (lightsource.ca)
ANTIMONY ARSENATE1
Sodium1
  • Good results were also achieved with copper sulphate/sodium arsenate and copper sulphate/potassium dichromate mixtures. (irg-wp.com)
Lipid Peroxidation1
  • Compared to barley, maize plants were more tolerant to arsenate-induced oxidative stress (less H2O2 and lipid peroxidation levels). (cu.edu.eg)
Arsenites2
  • Do you think your business should also be listed on this page - Arsenates, Arsenites (Formulated) in Richland (WA)? (richlandonline.us)
  • Ingestion is the main route of exposure to other arsenites and arsenates for the general population. (cdc.gov)
Copper2
  • While chromated copper arsenate (CCA) has proven to be exceptionally effective in protecting wood from rot and infestation, its toxic nature has led to the problem of disposal of CCA-treated lumber and remediation of waters and soils contaminated by process wastes. (mit.edu)
  • Old impregnated timber poles often contain chromated copper arsenate (CCA) or creosote, which may be hazardous to humans, animals or the environment if handled incorrectly. (caruna.fi)
SOILS1
  • We quantify and mechanistically discuss the physiological and biochemical basis of N. lucentensis-mediated plant biomass recovery on arsenate polluted soils. (cu.edu.eg)
Toxic2
  • Now, at the Weizmann Institute of Science in Israel , a team led by Dan Tawfik and Mikael Elias found GFAJ-1 is equipped with a "filtering" mechanism that single cells are known to use for keeping out toxic arsenate. (csmonitor.com)
  • The arsenite form was more toxic than arsenate. (who.int)
Enzymatic1
  • Facile enzymatic aldol reactions with dihydroxyacetone in the presence of arsenate. (tudelft.nl)
Varieties1
  • GSE4471: Expression data from rice varieties Azucena and Bala grown in 0 and 1ppm arsenate. (elsevier.com)
Found2
  • They found these proteins in GFAJ-1 are very specific - they don't bind easily to arsenate at all, despite the similarity to phosphate. (csmonitor.com)
  • The most significant relationship found was between ARSENATE and FREE IRON OXIDE s (r=0.748, a=0.01). (sid.ir)
Note1
  • Note: that as Erythrite is an arsenate stone, wash hands well after touching it, and preferably don't use against your bare skin. (healing-crystals-for-you.com)
Levels2
  • The selectivity is so good that the protein can be exposed to arsenate levels 3,000 times those in Mono Lake without binding to much of it at all, the researchers said. (csmonitor.com)
  • Detoxification (metallothionein, phytochelatin, glutathione-S-transferase levels) was upregulated in arsenate-exposed shoot and roots, and this response was further enhanced upon S5 supplementation, particularly in barley and maize roots. (cu.edu.eg)
Slightly1
  • An arsenate ion has a slightly different shape than a phosphate ion. (csmonitor.com)
Specific1
  • Upon arsenate treatment, N. lucentensis S5 stimulated root citric acid production and the plant's innate detoxification capacity in a species-specific manner. (cu.edu.eg)
