4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol Kinase

In enzymology, a 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol kinase (EC 2.7.1.148) is an enzyme that catalyzes the chemical reaction

ATP + 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol ADP + 2-phospho-4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol

Thus, the two substrates of this enzyme are ATP and 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol, whereas its two products are ADP and 2-phospho-4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol.

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. This enzyme participates in biosynthesis of steroids.
