4-Diphosphocytidyl-2-C-methylerythritol (or CDP-ME) is an intermediate in the MEP pathway (non-mevalonate pathway) of isoprenoid precursor biosynthesis. It is produced by the enzyme 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (IspD) and is a substrate for CDP-ME kinase (IspE).[1][2][3]

Biochemical role

[edit]

CDP-ME is an intermediate in the non-mevalonate pathway for the biosynthesis of the isoprenoid precursors isopentenyl pyrophosphate and dimethylallyl pyrophosphate.[4][5] Most gram-negative bacteria, the photosynthetic cyanobacteria and green algae use only this pathway, while higher plants also use the mevalonate pathway.[6][7]

The enzyme 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase combines 2-C-methylerythritol 4-phosphate and cytidine triphosphate to form CDP-ME, with a pyrophosphate (PPi) fragment as a byproduct:[8][9]

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