微生物法合成红景天苷

Microbial synthesis of salidroside

摘要:

红景天苷是红景天属植物的主要有效成分之一，具有耐缺氧、抗辐射、抗疲劳、抗肿瘤、降血糖、提高免疫力等多重功效。随着其需求量的日益增加和植物资源的不断减少，微生物法合成红景天苷因具有周期短和易调控等优势而倍受关注。目前微生物法合成红景天苷尚处于基础研发阶段，为了方便相关领域研究者系统了解其研究现状和探讨其未来发展方向，文中对红景天苷生物合成途径、糖基转移酶、野生菌/天然酶资源和工程菌/重组酶体系进行了综述。

Abstract:

Salidroside, as one of the main active ingredients of Rhodiala plant, has the effects of anti-hypoxia, anti-radiation, anti-fatigue, anti-tumor, hypoglycemia and improving immunity. With the increasing demand for salidroside and the decreasing of plant resources, microbial production of salidroside has attracted much attention due to its advantages of short period and easy controlling. At present, microbial production of salidroside is still at the basic research stage. In order to make it easier for researchers to understand the advances of microbial synthesis of salidroside, the biosynthesis pathways, uridine diphosphate glucosyltransferases, wild strain/natural enzymes and engineered strain/recombinant enzymes were reviewed.
