  • Title: [Perillyl alcohol production by engineered heterologous mevalonate pathway in Escherichia coli].
    Author: Qin Z, Zhang R, Yu J.
    Journal: Sheng Wu Gong Cheng Xue Bao; 2018 May 25; 34(5):722-730. PubMed ID: 29893080.
    Abstract:
    Perillyl alcohol, [4-isopropylene-1-cyclohexene] methanol, is a monocyclic monoterpene alcohol with special odorous similar to that of linalool and terpineol. It has application potential in pharmaceutical, daily chemical and food industries. In this study, one method for the synthesis of perillyl alcohol through the MVA pathway was studied. First, the MVA metabolic pathway originated from Enterococcus faecalis was constructed in Escherichia coli to synthesize limonene. Limonene was further transformed to perillyl alcohol by the hydroxylation of cytochrome P450 alkane hydroxylase. Furthermore, the shake flask fermentation condition of the engineered E. coli strain was optimized. The results showed that the engineered E. coli could produce about 50.12 mg/L perillyl alcohol through MVA pathway using glucose as raw material. In this study, the method of the MVA pathway for perillyl alcohol synthesis was constructed successfully in engineered E. coli, which provides both theoretical and technical support for terpenoids biosynthesis. 紫苏醇，即[4-异丙烯基-1-环己烯]甲醇，是一种具有类似芳樟醇和松油醇特殊气味的单环单萜烯醇。在医药、食品和化妆品等行业具有广阔市场空间和研究价值。文中研究了以工程大肠杆菌通过甲羟戊酸途径合成紫苏醇的方法。首先在大肠杆菌中构建来源于粪肠球菌的MVA代谢途径合成柠檬烯，随后柠檬烯通过细胞色素P450烷烃羟化酶的羟基化转化为紫苏醇。然后将构建的紫苏醇合成菌株在摇瓶发酵条件下进行优化，研究发现工程大肠杆菌以葡萄糖为原料，通过MVA 代谢途径可合成约50.12 mg/L 的紫苏醇。本研究构建合成紫苏醇的MVA 代谢途径也可用于其他萜类化合物的合成，为今后生物法合成萜类化合物提供了理论依据和技术支持。.
