  Glycosyltransferases: An Efficient Tool for the Enzymatic Synthesis of Oligosaccharides and Derivatives as well as Mimetics Thereof

  摘要：

  过去20年的研究揭示了碳水化合物在许多生物学过程中的作用，例如在细胞黏附过程、信号转导、恶性转化或病毒和细菌细胞表面识别中的作用。因此，碳水化合物及其结构类似物被认为是潜在的新线索。虽然碳水化合物的化学合成已经得到了很好的建立，但特定寡糖的制备仍然是一项昂贵而繁琐的挑战。化学合成的补充方法是使用酶法。由糖基转移酶催化的单糖基团转移到天然底物上，具有出色的化学、区域和立体选择性。此外，酶促糖基化允许合成碳水化合物衍生物甚至类似物。我们的研究结果显示，岩藻糖转移酶VI（EC 2.4.1.65）和III（EC 2.4.1.65），以及（2-3）-唾液酸转移酶ST3Gal III（EC 2.4.99.6）具有显著的合成潜力。我们演示了它们在制备寡糖及其衍生物和类似物方面的应用。

  Recombinant rat alpha(2-->3)-sialyltransferase (ST3Gal III, EC 2.4.99.6) was expressed from baculovirus infected Sf 9 insect cells in preparative amounts. In order to elucidate substrate tolerances of ST3Gal III, the natural type I and type II substrates 21 and 22 as well as several non-natural sugars were investigated. The non-natural Gal-beta(1 --> 3)Gal-(N) (type III) disaccharides 11, 13, and 16 turned out to be surprisingly good substrates for ST3Gal III. All sialylations were run in preparative scale and kinetic parameters (V-max and K-m) were determined.

  2-deoxy substituent Z is azido, amino, propionamido, or acetamido, were prepared by chemical synthesis. Both types of modified trisaccharides are acceptors for a fucosyltransferase preparation obtained from human milk. Preparative fucosylations using this enzyme provided analogues of the sialyl Lewis(x) and sialyl Lewis(a) tetrasaccharide structures, which have been proposed to be ligands for cell-adhesion
