摘要:使用重叠延伸pcr合成了来自嗜酸,嗜热古生菌picrophilus Torridus的海藻糖合酶(tsase)基因,并转化到大肠杆菌中进行表达.纯化的重组托德氏假单胞菌tsase(ptts)的最佳ph值和温度分别为6.0和45摄氏度,该酶在ph 5.0和60摄氏度下保持高活性.动力学分析表明,该酶的活性是2.5倍麦芽糖比海藻糖具有更高的催化效率(k(cat)/ K(m)),表明麦芽糖是优选的底物.酶将麦芽糖转化为海藻糖的最大转化率与底物浓度无关,在较低温度下趋于增加,并在20摄氏度时达到约71%.hg2+,Al3 +和sds抑制了酶的活性.

标题:Method of chemical synthesis of single-chain antibody fragments and products thereby obtained
发明人：FIGINI MARIANGELA; LUISON ELENA
权利人:GLYTECH INC; FIGINI MARIANGELA
摘要:A new method is disclosed for the protein full-chemical synthesis of single-chain antibody fragments (scFv); the obtained products are structurally close and functionally equivalent to their biological counterpart, being however, advantageously free of impurities and more reproducible in properties. The method includes the general steps of: (a) separately synthetizing sub-sequences (peptide fragments) (b) sequentially assembling the sub-sequences obtained in step (a) in the order as they appear in the target scFv amino acid sequence, and (c) performing oxidative folding of the assembled whole peptide molecule obtained in step (b) and dialyzing the resulting product in a buffer.

权利人:SEROBIOLOGIQUES LAB SA
摘要:A method for the enzymatic synthesis of sucrose ester, comprises introducing, in an adapted reactor and so as to form a reaction medium, predetermined amounts of an organic solvent, a sugar or a sugar derivative, a compound donor of acyl groups and an enzymatic catalyst, the amount of at least one constituent of the reaction mixture being deficient, in controlled addition during the reaction of additional amounts of the deficient constituent(s), and finally purifying the resulting sucrose esters at least by separating the fine enzymatic particles from the solvent.

标题:Process for synthesis of poly-gamma-glutamic acid
发明人：DHARNE MAHESH SHANTAPPA; NAIR PRANAV GIRIJAVALLABHAN
权利人:COUNCIL SCIENT IND RES
摘要:The present invention overcomes the problem of processes yielding poor quantities of poly-gamma-glutamic-acid (γ-PGA) by providing a process and a novel medium for synthesis of γ-PGA in the presence of Bacillus paralicheniformis MCC 196. Wherein, the novel medium comprises tomato waste alone for cost effective and greener production of γ-PGA with yield of 40 g/L. In another process, non-sterile fermentation employs the use of a medium high in sugar content. Wherein, sucrose is used in concentrations up to 50% to obtain more than 280 g/L of poly gamma glutamic acid. The disclosed process is scalable and provides immense economic advantages.

摘要:A polymer material, specifically a sugar backbone polymer and a synthesis method. A new type of sugar backbone polymer is prepared using a condensation and polymerization method. An addition reaction of alcohol-olefin is introduced into the synthesis of the sugar backbone polymer, to form a new functional primary sugar chain alternating polymer having alternating sugar and aliphatic units. It overcomes shortcomings of existing artificial chemical synthesis methods such as difficulty in controlling the stereoselectivity of the product, low molecular weight, cumbersome monomer preparation and few types. The molecular weight of the prepared polymer can reach 71,067 g/mol, and monomer preparation is simple.
