4-Diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate (or CDP-MEP, 4-diphosphocytidyl-2C methylerythritol 2-phosphate) is an intermediate in the MEP pathway of isoprenoid precursor biosynthesis.

It is formed by CDP-ME kinase (IspE) and is a substrate for 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase (IspF).[1]

Biochemical role

[edit]

CDP-MEP is an intermediate in the non-mevalonate pathway for the biosynthesis of the isoprenoid precursors isopentenyl pyrophosphate and dimethylallyl pyrophosphate.[2][3] Most gram-negative bacteria, the photosynthetic cyanobacteria and green algae use only this pathway, while higher plants also use the mevalonate pathway.[4][5]

The enzyme 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol kinase uses the cofactor, adenosine triphosphate (ATP) to introduce a terminal phosphate group to the immediate precursor, 4-diphosphocytidyl-2-C-methylerythritol (CDP-ME), giving CDP-MEP and adenosine diphosphate (ADP):[6]

The next reaction, catalyzed by 2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase, splits CDP-MEP into 2-C-methyl-D-erythritol 2,4-cyclic diphosphate (MEcPP) and cytidine monophosphate.[7]
