标题:Cell-free synthesis of DNA by strand displacement
发明人：PORTER NEIL; ROTHWELL PAUL; EXTANCE JONATHAN
权利人:TOUCHLIGHT IP LTD
摘要:The present invention relates to an improved process for synthesis of DNA, RNA, proteins and like molecules, in particular cell-free enzymatic synthesis of DNA, preferably in large scale. The present invention relates to the synthesis of DNA using strand-displacement replication and the addition of nucleotides to the reaction mixture is controlled, thus controlling yield. The reaction mixture contains a starting amount of nucleotides, polymerase and DNA template, to which further nucleotides are supplied in a controlled manner.

标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof
发明人：GARMSHAUSEN YVES
权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

标题 :Modulation of Enzymatic Polynucleotide Synthesis Using Chelated Divalent Cations
发明人：GRISWOLD JR KETTNER JOHN FREDERICK; LEE HOWON; CHURCH GEORGE M
权利人:HARVARD COLLEGE
摘要:Methods and apparatus of modulating polynucleotide synthesis are provided. The methods include delivering reagents comprising enzymes, nucleotides and ions to oligonucleotide primers wherein the reagents catalyze incorporation of the nucleotides to 3′ ends of the oligonucleotide primers, and modulating incorporation of the nucleotides to the 3′ ends of the oligonucleotide primers. Polynucleotide synthesis is modulated by modulating presence or absence of catalytic cation cofactors to provide sequence defined synthesis of polynucleotides. In certain embodiments, the polynucleotides encode information.

标 题:Dna synthesis yield improvements
发明人：ROTHWELL PAUL; KYSH DANIEL; PORTER NEIL
权利人:TOUCHLIGHT IP LTD
摘要:The present invention relates to an improved process for synthesis of deoxyribonucleic acid (DNA), in particular cell-free enzymatic synthesis of DNA, preferably on a large or industrial scale, with an improved yield and/or with an improved efficiency. The invention requires the use of nucleotide complexes wherein the nucleotide is associated with a mixture of divalent and monovalent cations. Preferably, the divalent cation may be magnesium or manganese.

标题 :Biosynthetic production of 7-[1',2',6',7',8',8a'(R)-hexahydro-2'(S),6'(R)-dimethyl-8'(S)-hydroxy-1'(S)-naphthyl]-3(R),5(R)-dihydroxyheptanoic acid (triol acid)

摘要:Biosynthetic production of 7-[1',2',6',-7',8',8a'(R)-hexahydro-2'(S),6'(R)-dimethyl-8'(S)-hydroxy -1'(S)-naphthyl]-3(R),5(R)-dihydroxyheptanoic acid, 'triol acid', is accomplished by enzymatic hydrolysis of lovastatin acid or a salt thereof, by treating it with Clonostachys compactiuscula ATCC 38009 or ATCC 74178, or mutants thereof, or a cell-free extract derived therefrom, or a hydrolase derived therefrom. The triol acid and its lactone form are both inhibitors of HMG-CoA reductase and thus useful as anti-hypercholesterolemic agents, and may also serve as intermediates for preparation of other HMG-CoA reductase inhibitors. Also, in the synthesis of simvastatin by direct methylation of lovastatin, selective hydrolysis of residual lovastatin salt by treatment with Clonostachys compactiuscula ATCC 38009 or ATCC 74178 or mutants thereof or a cell-free extract derived therefrom, or a hydrolase derived therefrom yields the 'triol' salt which can be easily separated from simvastatin.
