ATP + 4-diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate ADP + 4-diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate

Thus, the two substrates of this enzyme are ATP and 4-diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate (CDP-ME), whereas its two products are ADP and 4-diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate (CDP-MEP).

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol 2-phosphotransferase. This enzyme is also called CDP-ME kinase, and IspE. This enzyme participates in the MEP pathway (non-mevalonate pathway) of isoprenoid precursor biosynthesis.
