中文摘要：

UDP-糖基转移酶催化糖基转移反应,将糖基从活化的供体分子转移到受体分子上,从而调节受体分子在细胞和机体内的活性,如生物活性、溶解性和转运性。糖苷化是植物次生代谢较为普遍的修饰反应,在调节植物体内激素平衡、解除外源毒素毒性以及次生代谢产物的合成和贮存等方面发挥重要功能。本文就与植物次生代谢产物、植物激素及生物异源物质糖苷化相关的UDP-糖基转移酶的生化特性和功能研究进展进行综述,以期为本领域相关研究提供一定的参考。

英文摘要：

Uridine diphosphate glycosyltransferase（UGT） regulates the bioactivity,solubility and transportation of receptors within the cells through modulating glycosyl transfer reaction.Glycosylation is a ubiquitous modification of plant secondary metabolism that is involved in various functions,such as hormone homeostasis,the detoxification of exogenous toxins,and the biosynthesis and storage of secondary compounds.Herein,we have summarized the recent advances in biochemical properties and functions of these glycosyltransferases related to the glycosylation of secondary metabolites,phytohormones and xenobiotics,in order to provide some references for related studies in this field.
