标题:Significantly Improved Equilibrium Yield Of Long-Chain Alkyl Glucosides Via Reverse Hydrolysis In A Water-Poor System Using Cross-Linked Almond Meal As A Cheap And Robust Biocatalyst
摘要:An Array Of Ten Beta-D-Glueopyranosides With Varied Alkyl Chain Lengths Were Enzymatically Synthesized. It Was Found That For Longer Alkyl Chains A Lower Initial Rate And Final Yield Of Glucoside Was Obtained Except For Methyl Glucoside Because Of The Severe Toxicity Of Methanol To The Enzyme. From A Thermodynamics Point Of View,The Equilibrium Constant And Gibbs Free Energy Variation Of The Glucoside Syntheses Were Systematically Investigated. To Improve The Final Yields Of The Glucosides Containing Long Alkyl Chains The Equilibrium Of The Enzymatic Glucoside Synthesis Was Altered. The Equilibrium Yield Of Decyl Beta-D-Glucoside Increased From 1.9% To 6.1% When The Water Content Was Reduced From 10% To 5% (V/v) Using Tert-Butanol As A Cosolvent And 0.10 Mol/l Of Glucose As A Substrate. As For The Other Longer Alkyl Chain Glucosides,Heptyl Beta-D-Glucoside Was Found To Have Significant Surface Activity As Well.

标题:Lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides

摘要:The present invention relates to methods and compositions for lipid matrix-assisted chemical ligation and synthesis of membrane polypeptides that are incorporated in a lipid matrix. The invention is exemplified in production of a prefolded membrane polypeptide embedded within a lipid matrix via stepwise chemoselective chemical ligation of unprotected peptide segments, where at least one peptide segment is embedded in a lipid matrix. Any chemoselective reaction chemistry amenable for ligation of unprotected peptide segments can be employed. Suitable lipid matrices include liposomes, micelles, cell membrane patches and optically isotropic cubic lipidic phase matrices. Prefolded synthetic and semi-synthetic membrane polypeptides synthesized according to the methods and compositions of the invention also permit site-specific incorporation of one or more detectable moieties, such as a chromophore, which can be conveniently introduced during synthesis. The methods and compositions of the invention have multiple uses. For example, they can be used to assay ligand binding to membrane polypeptides and domains comprising a receptor, and thus are extremely useful for structure/function studies, drug screening/selection/design, and diagnostics and the like, including high-throughput applications. The methods and compositions of the invention are particularly suited for FRET analyses of previously inaccessible membrane polypeptides.

摘要:Provided herein are products and processes for efficiently synthesizing biomolecules in vitro using cell-free extracts derived from mammalian cells and insect cells. In an embodiment, provided is a process for preparing a cell-free extract from insect cells and mammalian cells that efficiently synthesizes post-translationally modified target proteins (e.g., glycosylated target proteins). In some embodiments, a ribonucleic acid is synthesized in vitro that comprises a cap, a 5′ untranslated region comprising an 18S rRNA binding ribonucleotide sequence, and a target ribonucleotide sequence. It has been determined that such ribonucleic acids result in efficient in vitro synthesis of a target protein using cell-free extracts derived from non-rabbit mammalian cells and insect cells.
