CC -!- FUNCTION: Bifunctional enzyme that catalyzes the formation of 4-
CC diphosphocytidyl-2-C-methyl-D-erythritol from CTP and 2-C-methyl-D-
CC erythritol 4-phosphate (MEP) (IspD), and catalyzes the conversion of 4-
CC diphosphocytidyl-2-C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-
CC methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding
CC release of cytidine 5-monophosphate (CMP) (IspF). {ECO:0000256|HAMAP-
CC Rule:MF_01520}.
