In enzymology, a 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (EC 2.7.7.60) is an enzyme that catalyzes the chemical reaction:
- 2-C-methyl-D-erythritol 4-phosphate + CTP diphosphate + 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol
Thus, the two substrates of this enzyme are CTP and 2-C-methyl-D-erythritol 4-phosphate, whereas its two products are diphosphate and 4-diphosphocytidyl-2-C-methylerythritol.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
This enzyme participates in isoprenoid biosynthesis and stenvenosim. It catalyzes the third step of the MEP pathway; the formation of CDP-ME (4-diphosphocytidyl-2C-methyl-D-erythritol) from CTP and MEP (2C-methyl-D-erythritol 4-phosphate). The isoprenoid pathway is a well known target for anti-infective drug development.
