DMAPP (Dimethylallyl pyrophosphate) serves as a pivotal isoprenoid precursor within the realm of biogenic isoprenoid synthesis. It finds its origin as a metabolic product originating from two primary pathways: the mevalonate pathway and the MEP (2-C-methyl-D-erythritol 4-phosphate) pathway, both being prominent conduits for isoprenoid precursor biosynthesis in diverse biological systems. Remarkably, DMAPP stands as an isomeric counterpart to isopentenyl pyrophosphate (IPP), constituting a prevalent molecular entity that ubiquitously permeates the living kingdom[1-2].

DMAPP(二甲基焦磷酸烯丙基)是生物源类异戊二烯合成过程中一个关键的类异戊二烯前体。它起源于两个主要途径的代谢产物:甲羟戊酸途径和MEP (2-C-methyl-D-erythritol 4-phosphate)途径,两者都是不同生物系统中类异戊二烯前体生物合成的重要通道。值得一提的是,DMAPP作为焦磷酸异戊烯基(IPP)的异构体,在生物中普遍存在[1-2]。
