标题:Method for rapid in vitro synthesis of glycoproteins via recombinant production of N-glycosylated proteins in prokaryotic cell lysates
发明人：JEWETT MICHAEL CHRISTOPHER; STARK JESSICA CAROL; DELISA MATTHEW P; JAROENTOMEECHAI THAPAKORN

摘要:Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated proteins. The glycosylated proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated 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 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.

标题 :Solid phase synthesis of peptides with carboxyl-terminal amides
发明人：GROSS ERHARD
权利人:US HEALTH
摘要:The method of utilizing α,β-unsaturated amino acids, acyl, and N-acyl derivatives as linking agents in the solid phase synthesis of peptides with the corresponding production of carboxyl terminal amides. Preferred unsaturated amino acids are dehydroalanine and dehydrobutyrine which are constituents in naturally occurring amides such as nisin and subtilin. The synthesis follows conventional lines of R. B. Merrifield et al including blocking of the amino nitrogen, with the exception that the release agent contains an amount of water equimolar to the reactant α,β-unsaturated amino acid.

摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.

标 题 :Enzymatic synthesis of chiral amines using -2-amino propane as amine donor
发明人：WU WEI; BHATIA MOHIT B; LEWIS CRAIG M; LANG WEI; WANG ALICE L; MATCHAM GEORGE W
权利人:CELGRO
摘要:2-Aminopropane is used as the amine donor in the stereoselective synthesis of a chiral amine from a ketone with a transaminase. In a typical embodiment, (S)-1-methoxy-2-aminopropane is prepared by bringing methoxyacetone into contact with a transaminase in the presence of 2-aminopropane as an amine donor until a substantial amount of methoxyacetone is converted to (S)-1-methoxy-2-aminopropane and 2-aminopropane is converted to acetone. In a second embodiment, L-alanine is prepared by bringing pyruvic acid into contact with a transaminase in the presence of 2-aminopropane as an amine donor.
