摘要
糖基转移酶(glycosyltransferases, GTs)广泛存在于各种有机体中,通过糖基化反应参与维持细胞代谢稳态.糖基转移酶能够识别多种受体,催化活化的糖基从供体分子转移到受体分子上,改变受体分子的化学稳定性、水溶性以及受体分子的转运能力和生物活性等,进而有助于提高其生物利用度和生物活性等.许多被糖基化修饰的化合物成为药物分子的重要来源.然而,天然产物中的糖苷类化合物存在含量低、提取难度大和提取产物纯度差等问题.在利用化学合成方法合成糖苷类化合物的过程中,无法实现特定位点的糖基化修饰,同时原料试剂和副产物易对环境造成污染.因此,近年来对糖基转移酶的研究日渐增多.本文简要综述了植物糖基转移酶的结构和生物技术应用的研究进展,为基于植物糖基转移酶结构的糖基化工程和生物活性糖苷化合物的生产提供有用信息.
