标题:Synthesis of d-allulose
发明人：KOCH TIMO JOHANNES; KIPPING FLORIAN; BUTZ STEFFEN; LESCH MARCEL; HÄSSLER THOMAS
权利人:PFEIFER & LANGEN GMBH & CO KG
摘要:The invention relates to a process for the synthesis of a product saccharide, preferably of D-allulose from an educt saccharide, preferably from D-fructose under heterogeneous or homogeneous catalysis which includes chemical and/or enzymatic catalysis. The synthesis is performed in at least two reactors that are arranged in series and the reaction product exiting the first reactor is subjected to chromatographic separation before it enters the second reactor. Preferably, the chromatographic separation is integrated in a simulated moving bed.

摘要:DNA sequences coding for enzymes capable of facilitating the synthesis of linear â–¡-1,4 glucans in plants, fungi and microorganisms. The invention relates to DNA sequences Coding for proteins having the enzymatic activity of an amylosucrase which allows the synthesis of linear â–¡1,4 glucans from the substrate sucrose by bacteria, fungi and plants or in cell-free systems. The invention furthermore describes plasmids and bacteria containing these DNA sequences as well as processes for the production of plants and microorganisms capable of intracellularly or extracellularly expressing a polypeptide having amylosucrase activity. The invention furthermore relates to the production of pure fructose using proteins exhibiting the enzymatic activity of amylosucrase.

标题:Process for the synthesis of polyol fatty acid polyesters
发明人：WILLEMSE GERARDUS W
权利人:UNILEVER NV; UNILEVER PLC
摘要:The application pertains to a process for the synthesis of polyol fatty acid polyesters, in which a polyol and/or a fatty acid oligoester thereof, is esterified by reaction with fatty acid lower alkylester under substantially solvent-free conditions at elevated temperature in the presence of a transesterification catalyst and, optionally an emulsifier, and in which at least during the final stage of the transesterification reaction the reaction mixture is submitted to the action of a stripping agent suitable for accelerating the removal of the lower alkyl alcohol formed in said reaction. The process is of particular advantage in the synthesis of polyesters of very high degrees of conversion.

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.

权利人:FUJIMORI KOGYO CO
摘要:A method for a synthesis of anhydrothrombin is provided which features a short process, an easy procedure, and high yields. n The method comprises n (A) a step of causing an active serine residue site of thrombin to react with an inhibitor, n (B) a step of performing an alkali treatment at a pH of not less than 11, and n (C) a step of performing an operation of recovery, and carries out these steps sequentially in the order mentioned, and is characterized by causing at least the step of performing the operation of recovery to proceed in the presence of at least one compound selected from the group consisting of polyhydric alcohols and saccharides, and a salt or an amphoteric electrolyte.
