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 ECO:0000269|PubMed:12499535}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_00107,
CC ECO:0000269|PubMed:12499535};
CC Note=Binds 1 divalent metal cation per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00107, ECO:0000269|PubMed:12499535};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Temperature dependence:
CC Thermostable. {ECO:0000269|PubMed:12499535};
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 ECO:0000269|PubMed:12499535}.
CC -!- SIMILARITY: Belongs to the IspF family. {ECO:0000255|HAMAP-
CC Rule:MF_00107, ECO:0000305}.
