摘要:苯丙氨酸解氨酶 (Pal) 催化l-苯丙氨酸可逆转化为相应的反式肉桂酸,从而提供了一条获得光学纯 α-氨基酸的途径.我们探索了生菜(Lactuca Sativa L.)基因组中编码的所有五种 Pal 的催化功能,此前已知这些 Pal 与伤口褐变有关.所有ls Pal 在氨消除反应中均对l-苯丙氨酸具有活性,并在 55-60 oc 和 Ph 9.0-9.5 时表现出最大活性.然而,其中的四种(Ls Pal1-Ls Pal4)表现出比ls Pal5 显着更高的活性和热稳定性,以及更广泛的底物谱,包括一些具有空间要求或给电子取代基的具有挑战性的底物.对最好的ls Pal3 进行了一组 21 种外消旋苯丙氨酸衍生物的动力学拆分,以及 21 种肉桂酸衍生物的氨加成.它在大多数情况下表现出优异的对映选择性,并且对于许多具有挑战性的非天然底物,其活性明显优于之前描述的 Pal,这证明了其在生物催化方面的巨大潜力.

摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.

摘要:The invention provides an amphiphilic coating for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, comprising a hydrophilic chemical structure and a lipophilic group, wherein said peptides and small molecular compounds differ from spot to spot from each other in the chemical structure, characterized in that said amphiphilic coating possesses low wettability to polar aprotic solvents used in the array synthesis; said amphiphilic coating possessing low wettability is designed that it can be converted to a coating possessing high wettability by hydrolysis of the lipophilic group; and said amphiphilic coating comprises an amino group for the reaction with an electrophilic reagent. The invention further provides a solid support comprising said amphiphilic coating and a method for method for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, wherein said planar surface of a solid support comprises said amphiphilic coating. Said method includes the enhancing of the wettability of a glass surface to organic solvents to realize automated on-demand biomolecular array synthesis comprising both, peptides and small molecular compounds. The amphiphilic surface can be switched to a hydrophilic surface, resulting in high density arrays suitable for protein- and cell-based screening.
