  Substrate specificity and carbohydrate synthesis using transketolase

  摘要：

  This paper describes the use of the enzyme transketolase as a catalyst in organic synthesis. The properties of transketolase from both yeast and spinach were investigated. The yeast enzyme was found to be more convenient for routine use. Examination of the substrate specificity of yeast transketolase demonstrated that the enzyme accepts a wide variety of 2-hydroxy aldehydes as substrates. A practical protocol for transketolase-catalyzed condensation of hydroxypyruvic acid with these aldehydes has been developed and used for the synthesis of four carbohydrates: L-idose, L-gulose, 2-deoxy-L-xylohexose, and L-xylose.

  L-岩藻糖类似物的短酶法合成

  摘要：

  报道了合成非极性末端修饰的 L-岩藻糖类似物的短酶促路线。特别是，已经制备了带有扩展的线性 (1b) 和支化 (1e) 饱和或各种不饱和 (1c, 1d) 脂族链的岩藻糖衍生物，以增加疏水接触。相当普遍的方法包括顺序应用来自大肠杆菌的重组酶 L-岩藻糖 1-磷酸醛缩酶 (FucA) 和 L-岩藻糖酮醇异构酶 (FucI)。从合适的羟基醛前体和磷酸二羟基丙酮作为容易获得的组分开始，以高达 30% 的总产率制备了对映体纯的 L-岩藻糖类似物。

• Recombinant 2-Deoxyribose-5-phosphate Aldolase in Organic Synthesis: Use of Sequential Two-Substrate and Three-Substrate Aldol Reactions

  A new procedure has been developed for the large scale preparation of recombinant 2-deoxyribose-5-phosphate aldolase (DERA, EC 4.1.2.4) from E. coli strain DH5 alpha (ATCC 86963). The enzyme was purified to homogeneity with an overall yield of 83% and in sufficient quantity to grow crystals suitable for X-ray diffraction studies. Using the sequential two- or three-substrate aldol reaction, DERA was applied to the synthesis of a variety of sugar analogs including deoxyriboses, 2-deoxyfucose analogs, dideoxyhexoses, trideoxyhexoses, deoxythiosugars, and C-13-substituted 2-deoxyribose-5-phosphate.

  A practical procedure is reported for the use of the enzyme transketolase, from Escherichia coli, for asymmetric carbon-carbon bond synthesis. The reactions with the biocatalyst are conveniently carried out, on a gram scale, in unbuffered aqueous media by employing a pH autotitrator. An improved large scale synthesis of hydroxypyruvate is also reported. Copyright (C) 1996 Elsevier Science Ltd

  enzymatic route for the synthesis of L-fucose analogs modified at the nonpolar terminus is reported. In particular, fucose derivatives bearing extended linear (1b) and branched (1e) saturated, or various unsaturated (1c, 1d) aliphatic chains have been prepared, in order to increase hydrophobic contacts. The rather general approach involves a sequential application of the recombinant enzymes L-fuculose 1-phosphate
