In this article, a mechanism of arsenite [As(III)]resistance through methylation and subsequent volatization is described. Heterologous expression arsM from Rhodopseudomonas palustris was shown to confer As(III) resistance an arsenic-sensitive strain Escherichia coli. ArsM catalyzes the formation number methylated intermediates As(III), with trimethylarsine as end product. The net result loss arsenic, both medium cells. Because homologues are widespread in nature, microbial-mediated...
Subambient daytime radiative cooling (SDRC) provides a promising electricity- and cryogen-free pathway for global energy-efficiency. However, current SDRC systems require stringent surface designs, which are neither cost-effective nor eco-friendly, to selectively emit thermal radiation outer space simultaneously maximize solar reflectance. Here, generic method is developed upgrade the conventional building-coating materials with peculiar self-adaptive effect through combining particle...
Arsenic is the most common toxic substance in environment, ranking first on Superfund list of hazardous substances. It introduced primarily from geochemical sources and acted biologically, creating an arsenic biogeocycle. Geothermal environments are known for their elevated content thus provide excellent setting which to study microbial redox transformations arsenic. To date, studies communities geothermal have focused Bacteria Archaea , with little attention eukaryotic microorganisms. Here,...
Arsenic (As) is a pervasive and ubiquitous environmental toxin that has created worldwide human health problems. However, there are few studies about how organisms detoxify As. Cyanobacteria capable of both photolithotrophic growth in the light heterotrophic dark soils, aquatic systems, wetlands. In this study, we investigated As biotransformation three cyanobacterial species (Microcystis sp. PCC7806, Nostoc PCC7120, Synechocystis PCC6803). Each accumulated large amounts As, up to 0.39 g...
Summary • Biotransformation of arsenic includes oxidation, reduction, methylation, and conversion to more complex organic arsenicals. Members the class arsenite (As(III)) S-adenosylmethyltransferase enzymes catalyze As(III) methylation a variety mono-, di-, trimethylated species, some which are less toxic than itself. However, no methyltransferase gene has been identified in plants. Here, an arsM from soil bacterium Rhodopseudomonas palustris was expressed Japonica rice (Oryza sativa) cv...
Abstract Background A new method for the prediction of protein structural classes is constructed based on Rough Sets algorithm, which a rule-based data mining method. Amino acid compositions and 8 physicochemical properties are used as conditional attributes construction decision system. After reducing system, rules generated, can be to classify objects. Results In this study, self-consistency jackknife tests datasets by G.P. Zhou (Journal Protein Chemistry, 1998, 17: 729–738) verify...
The enzyme As(III) S-adenosylmethionine methyltransferase (EC 2.1.1.137) (ArsM or AS3MT) is found in members of every kingdom, from bacteria to humans. In these enzymes, there are three conserved cysteine residues at positions 72, 174, and 224 the CmArsM orthologue thermophilic eukaryotic alga Cyanidioschyzon sp. 5508. Substitution any led loss methylation. contrast, a C72A mutant still methylated trivalent methylarsenite [MAs(III)]. Protein fluorescence single-tryptophan reported binding...
Accumulation of arsenic has potential health risks through consumption food. Here, we inserted the arsenite [As(III)] S-adenosylmethionine methyltransferase (ArsM) gene into chromosome Pseudomonas putida KT2440. Recombinant bacteria methylate inorganic less toxic organoarsenicals. This for bioremediation environmental and reducing contamination in
Acidithiobacillus ferrooxidans has an arsenic resistance operon that is controlled by As(III)-responsive transcriptional repressor, AfArsR, a member of the ArsR/SmtB family metalloregulators. AfArsR lacks As(III) binding site ArsRs from plasmid R773 and Escherichia coli, which have Cys(32)-Val-Cys(34)-Asp-Leu-Cys(37) sequence in DNA site. In contrast, it three cysteine residues, Cys(95), Cys(96), Cys(102), are not present E. coli ArsRs. The results direct measurements x-ray absorption...
Enolase is a dimeric metal-activated metalloenzyme which uses two magnesium ions per subunit: the strongly bound conformational ion and catalytic that binds to enzyme−substrate complex inducing catalysis. The crystal structure of human neuronal enolase−Mg2F2Pi (enolase fluoride/phosphate inhibitory complex, EFPIC) determined at 1.36 Å resolution shows combination anions effectively mimics an intermediate state in phosphate same site as group substrate/product,...
Biological systems, ranging from bacteria and fungi to humans, can methylate arsenic. Recent studies have suggested that the AsIII S-adenosylmethionine methyltransferase (arsM) gene in was responsible for removal of arsenic as volatile arsines bacteria. However, there has been no direct measure released cultures. We describe here an integrated system incorporating bacterial incubation species analysis, we demonstrate its application identification produced The headspace cultures purged with...
Understanding spatial and temporal variations in river water quality quantitatively evaluating the trend of changes are important order to study efficiently manage resources. In this study, an analysis Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis Discriminant applied as integrated approach explore latent sources pollution Shanchong River basin, Northwest Basin Lake Fuxian, China. We group all field surveys into 2 clusters (dry season rainy season). Moreover, 14 sampling...
Transcription activator-like effectors (TALEs) secreted from Xanthomonas oryzae pv (Xoo) function as a pathogenicity factor to activate rice bacterial blight (BB) susceptibility, conforming the gene-for-gene paradigm well resistance. Xoo pathotypes generally harbor one three major TALEs targeting OsSWEET genes determine pathogenicity; conversely, immunity events mediated by minor have not been taken seriously. Here, we demonstrated that lipid transfer protein encoding gene OsLTPL23...
