摘要
萜类化合物是植物界广泛存在的一种次生代谢物质,其种类繁多,不仅在植物的生命活动中扮演重要的作用,而且还被广泛的应用于工业、医药卫生等方面。萜类化合物的合成包括甲羟戊酸和丙酮酸两条途径,二者都是以异戊烯基焦磷酸为主要的代谢中间产物。萜类化合物的合成较为复杂,其过程受多种酶协调控制,根据各种酶在萜类合成不同阶段的作用,可将其分为Ⅰ、Ⅱ、和Ⅲ类酶。当前人们对其研究主要是Ⅰ类和Ⅱ类酶,试图弄清其合成机理以生产更多有用的萜类化合物。本文综述了植物次生代谢物质萜类的生物合成途径,催化主要中间产物形成相关酶的研究进展,并对其研究前景作简要展望。
Terpenes are a huge group of organic compounds widely existing in plants. They not only play an important role in metabolism, but also are used to industry and medication. The biosynthesis pathways of terpenes include mevalonate pathway and pyruvate/glyceraldehydes-3-phosphate pathway. All these pathways seem isopenteny pyrophosphate as the primary production and controlled by many different enzymies. According to different step role they can be divided into I, II, and III. At present people mainly study I and II in order to make clear their synthetical mechanism. This article reviewes the key enzymes relation with biosynthesis pathways of terpenes and their research foreground.
