Enzymatic epoxide-opening cascade is one of the key biosynthetic processes for constructing structurally diverse polyethers. Here we report the first in vitro analysis of the cyclization catalyzed by two epoxide hydrolases, MonBI and MonBII involved in monensin biosynthesis, using simple epoxy-alcohols and the unprecedented synergistic effect on the epoxide-opening activity between these epoxide hydrolases
酶促环氧化物开放级联反应是构建结构多样的聚醚的关键生物合成过程之一。在这里,我们报告了使用简单的环氧醇对参与莫能菌素生物合成的两种环氧水解酶MonBI和MonBII催化的环化进行的首次体外分析,这些环氧醇对这些环氧水解酶之间的环氧开放活性具有空前的协同作用。
