2-C-Methyl-d-erythritol cyclodiphosphate is converted into (E)-4-hydroxy-3-methylbut-2-enyl diphosphate by a cell-free system from an Escherichiacoli strain overexpressing the gcpE gene. The latter diphosphate, representing probably the last intermediate in the MEP pathway for isoprenoid biosynthesis, was identified by comparison with reference material obtained by chemical synthesis.
2- Ç -甲基d赤藓糖醇环二被转换成(Ë从由无细胞系统)-4-羟基-3-甲基丁-2-烯基二磷酸大肠埃希氏杆菌菌株过表达gcpE基因。通过与通过化学合成获得的参考物质进行比较,确定了后者的二磷酸酯,后者可能代表了类异戊二烯生物合成的MEP途径中的最后中间体。
