CC   -!- FUNCTION: Involved in the biosynthesis of isopentenyl diphosphate (IPP)
CC       and dimethylallyl diphosphate (DMAPP), two major building blocks of
CC       isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2-
CC       C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol
CC       2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine
CC       5-monophosphate (CMP). {ECO:0000255|HAMAP-Rule:MF_00107}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=4-CDP-2-C-methyl-D-erythritol 2-phosphate = 2-C-methyl-D-
CC         erythritol 2,4-cyclic diphosphate + CMP; Xref=Rhea:RHEA:23864,
CC         ChEBI:CHEBI:57919, ChEBI:CHEBI:58483, ChEBI:CHEBI:60377; EC=4.6.1.12;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00107};
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00107};
CC       Note=Binds 1 divalent metal cation per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_00107};
CC   -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC       via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC       phosphate: step 4/6. {ECO:0000255|HAMAP-Rule:MF_00107}.
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00107}.
CC   -!- SIMILARITY: Belongs to the IspF family. {ECO:0000255|HAMAP-
CC       Rule:MF_00107}.
