摘　　要：糖苷类抗生素是临床上广泛应用的抗菌和抗肿瘤化合物。该类化合物在体内由糖基转移酶催化,糖基化反应通常在抗生素生物合成的最后发生,糖基的位置、类型和数量对糖苷类抗生素的活性有很大的影响。本文综述了糖基转移酶的种类、功能、特性及其在组合生物合成中的应用与研究前景。Glycoside antibiotics, a category of compounds widely used clinically for anti-bacterial and anti-cancer, are catalyzed by antibiotic glycosyltransferases （Gtfs） in vivo. The sugar moieties are transferred to the corresponding aglycon by Gtfs, often work at very late stages of biosynthesis of antibiotics. The posi- tion, type and number of sugar moieties incorporated to the antibiotics have great impact on its bioactivity. This article provides an overview of the categories, functions, characteristics of Gtfs, their applications in combinatorial biosynthesis, and the prospects for research.
