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.

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.

标 题 :In Vitro Protein Synthesis Systems for Membrane Proteins that Include Adolipoproteins and Phospholipid Adolipoprotein Particles
发明人：KUDLICKI WIESLAW; FLETCHER JULIA; KATZEN FEDERICO
权利人:LIFE TECHNOLOGIES CORP
摘要:In vitro protein synthesis systems and methods are provided that produce membrane proteins in soluble form. In some aspects, the invention provides methods of synthesizing proteins using in vitro protein synthesis systems that include an apolipoprotein, in which higher yields of soluble protein are produced than in the absence of the apolipoprotein. Apolipoproteins useful in the present invention include naturally occurring apolipoproteins, as well as sequence variants of wild-type apolipoproteins, and engineered apolipoproteins. The apolipoproteins can be provided in an in vitro protein synthesis system associated with lipid or not associated with lipid. The invention also provides compositions and kits for synthesis of proteins in soluble form, in which the compositions and kits include cell extracts for protein translation and at least one apolipoprotein biomolecule.

标题 :Method and compositions for improved polynucleotide synthesis
发明人：YANG SHUWEI
权利人:GENECOPOEIA INC
摘要:The sensitivity and specificity of polynucleotide synthesis is increased by protecting the 3'-end of an oligonucleotide used as a primer in the synthesis of the polynucleotide. Protection of the 3'-end of an oligonucleotide prevents non-specific chain elongation. Removal of blocking group an elevated temperature, using a thermostable enzyme, permits template-specific polynucleotide synthesis. The present invention also provides oligonucleotides with a 3' end protected by a blocking group and a thermostable enzyme capable of removing the blocking group at an elevated temperature. The compositions and methods of the invention are very useful in a variety of techniques for DNA/RNA amplification and analysis, including medical genetics research and diagnosis, pathogen detection, forensic, and animal and plant genetics applications, among others.
