摘要
植物丝氨酸羧肽酶样酰基转移酶与丝氨酸羧肽酶相比具有相似的结构特点和很高的同源性,能够催化酰基葡萄糖酯的酰基转移反应,参与植物次生代谢产物的酰基化修饰,丰富天然产物结构多样性,改善化合物水溶性、稳定性等理化性质。本文重点介绍植物来源丝氨酸羧肽酶样酰基转移酶家族的结构特点、催化机制、功能鉴定及其生物催化应用等方面的研究进展,为促进此类酰基转移酶基因的功能表征和利用合成生物技术合成活性次生代谢产物提供参考。
Plant serine carboxypeptidase-like acyltransferases(SCPL-AT) have similar structural characteristics and high homology compared to the serine carboxypeptidase. They can transfer the acyl from acyl glucose esters to many natural products, participate in the acylation modification of plant secondary metabolites, enrich the structural diversity of natural products, and improve the physicochemical properties such as water solubility and stability of compounds. This review summarizes the structural characteristics, catalytic mechanism, functional characterization, and biocatalytic applications of SCPL-AT from plants. This will help to promote the functional characterization of these acyltransferase genes and the biosynthesis of useful plant secondary metabolites by synthetic biotechnology.
