标题 :Enhanced in vitro synthesis of biological macromolecules using a novel ATP regeneration system
发明人：SWARTZ JAMES R; KIM DONG-MYUNG
权利人:UNIV LELAND STANFORD JUNIOR
摘要:Compositions and methods are provided for the enhanced in vitro synthesis of biological molecules where ATP is required for synthesis. Of particular interest is the synthesis of polymers, e.g. nucleic acids, polypeptides, and complex carbohydrates. A homeostatic system is used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. Since inorganic phosphate can be an inhibitory by-product of synthesis, the period of time when synthesis is maintained in vitro can be extended. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.

标 题 :Total synthesis of northebaine, normophine, noroxymorphone enantiomers and derivatives via N-Nor intermediates
发明人：RICE KENNER CRALLE; NEWMAN AMY HAUCK
权利人:US HEALTH
摘要:The invention involves a method of making key intermediates useful in the synthesis of many opiate narcotics and antagonists and agonists; and the non-opiate enantiomers thereof which have potent antitussive properties. The synthesis starts from either the natural or unnatural enantiomer of nordihydrocodeinone and produces 8, 14-dihydronorthebaine, the diketal of 7-bromonordihydrocodeinone, northebaine, norcodeinone diketal and 14-hydroxynorcodeinone intermediates without the necessity of leaving the N-nor structure. The syntheses have fewer steps than previous methods, and also have high yields.

标 题:Synthesis of isoprenoids and derivatives
发明人：GONZALEZ RAMON; CLOMBURG JAMES M; CHEONG SEOKJUNG

摘要:This disclosure generally relates to the use of enzyme combinations or recombinant microbes comprising same to make isoprenoid precursors, isoprenoids and derivatives thereof including prenylated aromatic compounds. Novel metabolic pathways exploiting Claisen, aldol, and acyioin condensations are used instead of the natural mevalonate (MVA) pathway or 1-deoxy-d-xylulose 5-phosphate (DXP) pathways for generating isoprenoid precursors such as isopentenyl pyrophosphate (IPP), dimethylallyl pyrophosphate (DMAPP), and geranyl pyrophosphate (GPP). These pathways have the potential for better carbon and or energy efficiency than native pathways. Both decarboxylative and non-carboxylative condensations are utilized, enabling product synthesis from a number of different starting compounds. These condensation reactions serve as a platform for the synthesis of isoprenoid precursors when utilized in combination with a variety of metabolic pathways and enzymes for carbon rearrangement and the addition/removal of functional groups. Isoprenoid alcohols are key intermediary products for the production of isoprenoid precursors in these novel synthetic metabolic pathways.

标 题:In vitro synthesis of polypeptides by optimizing amino acid metabolism
发明人：SWARTZ JAMES ROBERT; KIM DONG-MYUNG
权利人:UNIV LELAND STANFORD JUNIOR
摘要:Compositions and methods are provided for the enhanced in vitro synthesis of polypeptides. In order to improve the performance of in vitro protein synthesis reactions, metabolic inhibitors, or manipulation of a source organism, is used to diminish or avoid the action of enzymes responsible for undesirable amino acids production or depletion. A homeostatic system may be used for production of ATP, where the required high energy phosphate bonds are generated in situ, e.g. through coupling with an oxidation reaction. The homeostatic energy source will typically lack high energy phosphate bonds itself, and will therefore utilize free phosphate in the reaction mix during generation of ATP. The homeostatic energy source is provided in combination with an enzyme that catalyzes the creation of high energy phosphate bonds and with an enzyme that can use that high energy phosphate bond to regenerate ATP.

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.
