Enzyme Information

2.7.7.60

2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase.

based on mapping to UniProt Q46893

CTP + 2-C-methyl-D-erythritol 4-phosphate = diphosphate + 4-(cytidine 5'-diphospho)-2-C-methyl-D-erythritol.

-!- ATP or UTP can replace CTP, but both are less effective. -!- GTP and TTP are not substrates. -!- Forms part of an alternative nonmevalonate pathway for terpenoid biosynthesis.
