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:0000255|HAMAP-Rule:MF_00108}.
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,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:37563,
CC         ChEBI:CHEBI:57823, ChEBI:CHEBI:58262; EC=2.7.7.60;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00108};
CC   -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC       via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC       phosphate: step 2/6. {ECO:0000255|HAMAP-Rule:MF_00108}.
CC   -!- SIMILARITY: Belongs to the IspD/TarI cytidylyltransferase family. IspD
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_00108}.
