标题:重新审视用第一行过渡金属将 Co2 还原为草酸盐:不可重复性,模糊分析和相互冲突的反应性
摘要:由 Co 2构建更高 C >= 2 的化合物构成了一个有吸引力的转变,其灵感来自大自然构建碳水化合物的策略.然而,使用对环境无害的还原剂控制二氧化碳形成的 C-C 键仍然是一项重大挑战.在这方面,Co 2还原二聚成草酸盐是一种重要的模型反应,能够研究这种最简单的 Co 2偶联反应的机理.在此,我们提出了在 Co 2还原过程中遇到的常见陷阱,尤其是其还原耦合,基于已建立的 Co 2转化协议变成草酸盐.此外,我们提供了一个例子来系统地评估这些反应.基于我们的工作,我们强调了使用合适的正交分析方法的重要性,并提高了对氧化反应的认识,这些氧化反应同样会导致草酸盐的形成而不掺入 Co 2.这些结果可以确定关键参数,这些参数可用于定制未来的催化系统,并将促进整个领域的进步.

标题 :Compositions and methods for rapid in vitro synthesis of bioconjugate vaccines in vitro via production and N-glycosylation of protein carriers in detoxified prokaryotic cell lysates

摘要:Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated carrier proteins. The glycosylated carrier proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated carrier proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated carrier proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

摘要:The present invention relates to a novel biocatalytic process for the stereoselective preparation of alpha amino amide compounds catalyzed by NHase enzymes. A further aspect of the invention relates to novel NHase enzymes as well as further improved NHase enzyme mutants, nucleic acid molecules encoding these enzymes, recombinant microorganisms suitable for preparing such enzymes and mutants. Another aspect of the invention relates to a chemo-biocatalytic process for the preparation of lactam compounds comprising the new catalytic process for the preparation of alpha amino amide compounds catalyzed by NHase enzymes, as well as the chemical oxidation of the alpha amino amide by applying certain chemical oxidation catalysts suitable for converting the alpha amino amide under retention of its stereochemical configuration to the respective lactam. The novel chemo-biocatalytic process is particularly suited for the synthesis of valuable pharmaceutical compounds, like in particular (S)-Levetiracetam.

摘要:The present invention provides a general salt-assisted chemical vapour deposition method for phase-controllable synthesis of 1T′ and 2H-phase transition metal dichalcogenide (TMD) monolayer crystals. The method comprises: mixing a transition metal compound powder and a salt powder to form a precursor; placing a substrate on top of the precursor; placing the precursor and the substrate at a center position in a chemical vapour deposition (CVD) furnace; placing a chalcogen powder at an upstream position relative to the precursor along a gas-flow direction in the CVD furnace; heating up the CVD furnace to a growth temperature within the heat-up time; keeping the CVD furnace at the growth temperature for a growth time under a mixed gas flow of H2 and Ar. The optical and electrical characterizations reveal the phase-dependent in-plane isotropy and anisotropy of the as-synthesized 2H and 1T′-phase crystals. The 1T′-TMD monolayer crystals demonstrate much-improved phase transition temperatures.

标 题 :Synthesis of linear and branched polymers of polypeptides through direct conjugation
发明人：ALBAYRAK CEM; SWARTZ JAMES R; LU YUAN
权利人:UNIV LELAND STANFORD JUNIOR
摘要:Methods are provided for a one step synthesis of polypeptide polymers or co-polymers. The polymers or co-polymers can be linear or branched. In the methods of the invention, the coding sequence for the polypeptide(s) to be polymerized is altered by introducing one or more codons for an nonnatural amino acid, which coding sequence is then utilized to produce the cognate polypeptide. The nonnatural amino acids are selected to be reactive with each other in a bioorthogonal reaction, and are combined in a conjugation reaction with the desired components of the polymer.
