摘要:在温和的条件下,两亲性吡啶鎓盐和重氮鎓盐被证明是两相(水/氯仿或水/二氯甲烷)硫氧化和n-氧化的有效催化剂.这种史无前例的氧化方法利用过氧化氢与简单的吡啶鎓或重氮鎓原子的共价键合来增加氢过氧化物种类的亲脂性,并随后将其活化以在非极性介质中氧化.发现催化效率取决于杂芳烃核的类型和催化剂的亲脂性.制备并研究了五种系列的杂芳烃催化剂:1-烷基-3,5-二氰基吡啶鎓,1-烷基-3,5-二硝基吡啶鎓,1-烷基-3-氰基吡啶鎓,1-烷基-4-氰基吡啶鎓和1-烷基-4-(三氟甲基)嘧啶鎓三氟甲磺酸酯(烷基=丁基,己基,辛基,癸基,十二烷基和十六烷基).其中,发现1-辛基-3,5-二硝基吡啶鎓和1-癸基-4-(三氟甲基)嘧啶鎓三氟甲磺酸酯是非常好的催化剂,表现出最佳的稳定性和最高的催化活性,相对于350倍的加速作用非催化反应.与使用过氧化氢的其他有机催化两相氧化相反,本方法的特点是化学选择性高,催化剂负载量低(5

摘要:We claim a method of expression a thioredoxin-fused membrane protein comprising expressing said thioredoxin-fused membrane protein in a cell-free protein synthesis system in the presence of a non-ionic detergent. It is preferable that the fused membrane protein which is a highly hydrophobic protein, e.g., a G protein-coupled receptor, can be produced in a state being highly soluble and capable of forming a biologically active three-dimensional structure. Also, this invention provides a recombinant polynucleotide encoding said thioredoxin-fused membrane protein which is expressed in the cell-free protein synthesis system.
