    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.

    Ganglioside GQ1b ? is the most potent antagonist of the Myelin-associated glycoprotein (MAG) identified so far. For the efficient synthesis of the partial structure of GQ1b ? and derivatives thereof, a chemo-enzymatic strategy using the ?(2?3)-sialyltransferase ratST3Gal III (EC 2.4.99.6) was applied. Besides the natural substrates Gal? (1?3)GlcNAc (19) and Gal? (1?4)GlcNAc (20), the disaccharides Gal? (1?3)GalNTCA?-OSE (9), Gal? (1?3)GalNAc?-OSE (11), and Gal? (1?3)Gal?-OSE (14) were also tolerated by the enzyme and were transformed to the target structures in preparative scale.

    Research over the past two decades has uncovered numerous biological roles for carbohydrates, e.g. in cell adhesion processes, signal transduction, malignant transformation, or viral and bacterial cell-surface recognition. Carbohydrates and structural analogues thereof are therefore considered as potential new leads. Although the chemical synthesis of carbohydrates is well established, the preparation of particular oligosaccharides still remains a costly and cumbersome challenge. A complementary approach to the chemical synthesis is the use of enzymatic methods. The transfer of monosaccharide moieties to natural substrates, catalyzed by glycosyltransferases, exhibits excellent chemo-, regio- and stereoselectivity. In addition, enzymatic glycosylations permit the synthesis of carbohydrate derivatives and even carbohydrate mimetics. Our results reveal a remarkable synthetic potential of fucosyltransferases VI (EC 2.4.1.65) and III (EC 2.4.1.65), and ? (2?3)-sialyltransferase ST3Gal III (EC 2.4.99.6). Their use for the preparative synthesis of oligosaccharides and derivatives as well as mimetics thereof is demonstrated.
