CC   -!- FUNCTION: Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D-
CC       erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).
CC       {ECO:0000256|HAMAP-Rule:MF_00108, ECO:0000256|SAAS:SAAS00786778}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-C-methyl-D-erythritol 4-phosphate + CTP + H(+) = 4-CDP-2-C-
CC         methyl-D-erythritol + diphosphate; Xref=Rhea:RHEA:13429,
