The linking of sugars to a variety of different proteins has an important influence on the function of cells. The biological catalysts or enzymes that speed up the reactions in which sugars are linked to other molecules are known as glycosyltransferases. Although these enzymes and are industrially and biologically important, they have not been extensively studied because they are difficult to produce in large amounts. In this project we will take advantage of our ability to produce significant quantities of glycosyltransferases that catalyse the transfer of the sugar mannose onto other molecules. The three dimensional structure of these enzymes will be determined and the information will be used to synthesise inhibitors of these biological catalysts and to use molecular engineering techniques to manipulate their biological properties.

糖与各种不同蛋白质的连接对细胞的功能有重要影响。加速糖与其他分子连接的反应的生物催化剂或酶被称为糖基转移酶。虽然这些酶在工业和生物学上很重要，但由于它们难以大量生产，因此尚未对其进行广泛研究。在这个项目中，我们将利用我们的能力，产生大量的糖基转移酶，催化转移的糖甘露糖到其他分子。这些酶的三维结构将被确定，这些信息将用于合成这些生物催化剂的抑制剂，并使用分子工程技术来操纵它们的生物学特性。
