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.
