The enantioselective Diels-Alder reaction of 1,2-dihydropyridines with aldehydes using an easily prepared optically active β-amino alcohol catalyst was found to provide isoquinuclidines, efficient synthetic intermediate pharmaceutically important compounds such as oseltamivir phosphate, a satisfactory chemical yield and enantioselectivity (up 96%, up 98% ee). In addition, the obtained highly pure isoquinuclidine converted piperidine having four successive carbon centers.
Hierarchical porous carbons are widely used as adsorbents, catalyst supports, electrode materials, and other applications because of their high specific surface area (SSA), varied pore structure, adjustable porosity, excellent physicochemical stability. Introducing heteroatoms such N, P, or S, with electronegativities different from that carbon, into the carbon skeleton can change chemical properties density electron cloud around matrix, thus altering interactions CO 2 molecules improving...
Bacteriorhodopsin (BR) is a light driven proton pump firstly found in the membrane of halophilic archaea. BR absorbs wide range visible with high quantum efficiency. To elucidate sensitizing effect BR, we tested photocatalytic degradation phenol BR-sensitized TiO 2 nanoparticles and compared that Alizarin red (AR). When concentration was 13.1 mg/L (4.9×10 -7 mol/L), 23.8% degradated after hours irradiation. The percentage 3.5 times higher than alone similar to sensitized by AR (20.1%)....
Phoborhodopsin from Halobacterium salinarum (salinarum phoborhodopsin, spR also called HsSR II) is a photoreceptor for the negative phototaxis of bacterium. A unique feature formation shorter wavelength photoproduct, P480, observed at liquid nitrogen temperature beside K intermediate. Formation similar photoproduct has not been reported in other microbial rhodopsins. This showed its maximum absorbance (λ(max)) 482 nm and can thermally revert back to above -160 °C. It was revealed that P480...
Wetting and drying are typical natural events in arid semiarid areas. In order to explore the contribution of microorganisms change soil phosphorus components during wetting processes, incubation experiments were conducted on calcareous from Inner Mongolia grasslands. By comparing various fractions between sterilized unsterilized soils, microbial effect available with moisture changes was studied. The results indicated that there no significant difference APi (NaHCO 3 -extractable inorganic...
Abstract Phoborhodopsin (pR; also called sensory rhodopsin II, SRII) is a photoreceptor of negative phototaxis halobacteria. The studies photochemical properties this pigment are not many because the amount small and stability low. Recently an expression system phoborhodopsin from Halobacterium salinarum (called phoborhodopsin, s pR; Hs in Escherichia coli purification method has been developed (Mironova et al. [2005] FEBS Lett. , 579, 3147–3151), which enables detailed on pR. In present...
To evaluate the effects of soil bacteria on contents water-soluble fluoride in high area, a total 225 isolates were firstly obtained from collected Xianghuangqi County Inner Mongolia, an typical area China. These grouped into 10 operational taxonomic units according to their 16SrRNA gene sequences using 97% sequence identity threshold. An isolate was randomly selected each group as representative strain study mineral weathering potentials, calcium precipitating and effect content soil. Most...
Abstract Aspartic acid 103 (D103) of sensory rhodopsin II from Halobacterium salinarum ( Hs SRII , or also called phoborhodopsin) corresponds to D115 bacteriorhodopsin BR ). This amino residue is functionally important in . work reveals that a substitution D103 with asparagine (D103N) glutamic (D103E) can cause large changes photocycle. These include (1) shortened lifetime the M intermediate following order: wild‐type > D103N D103E; (2) altered decay pathway 13‐ cis O‐like species. The...
Archaerhodopsins (ARs) is one of the members microbial rhodopsins. Threonine 164 (T164) and serine 165 (S165) residues AR from Halorubrum sp. ejinoor (HeAR) are fully conserved in ARs, although they far proton transfer channel retinal Schiff base, likely involved a hydrogen-bonding network at end Helix E where most rhodopsins assume "bent structure". In present work, T164 and/or S165 were replaced with an alanine (A), photocycles mutants analyzed flash photolysis. The amino acid replacements...
Salt lake environments are economically and ecologically important issues. Like any other ecosystems in the world, salt facing various kinds of pollutions. However, little information is available on biodegradation organic pollutants by halophilic microorganisms such environments. In present work we isolated a strain phenol-degradating bacteria from Inner Mongolia. Sequence 16S rRNA suggested that belong to Propionibacterium genus. The can grow with phenol as sole carbon source under 10%...
Microbial rhodopsins are photoactive proteins that use retinal molecule as the center and have been studied intensively an excellent model system for structural biology.We identified new microbial rhodopsin genes from halorubrum species isolated Ejinoor salt lake in Inner Mongolia.Pairs of PCR primers targeted bacteriorhodopsin (bR) gene or phoborhodopsin (pR) were made.We got full-length sequence bR-like by genome walking.The deduced amino acid has 87% identity with H.s. All acids important...
Abstract Aims The effect of drying and rewetting (DRW) on soil labile phosphorus has been extensively studied, while its the dynamics metastable fractions is poorly understood. This study aims to characterize changes in different during moisture fluctuation reveal driving force behind it. Methods Ca 2 -IP, 8 Al-IP Fe-IP were sequentially extracted subsequent four air-dried calcareous soils. -OP, MBP other properties also determined. Correlation analysis was conducted inter-transition these...
