CC -!- FUNCTION: Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-
CC 2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate.
CC {ECO:0000255|HAMAP-Rule:MF_00159}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E)-4-hydroxy-3-methylbut-2-enyl diphosphate + H2O + 2
CC oxidized [2Fe-2S]-[ferredoxin] = 2-C-methyl-D-erythritol 2,4-cyclic
CC diphosphate + H(+) + 2 reduced [2Fe-2S]-[ferredoxin];
CC Xref=Rhea:RHEA:26119, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001,

CC Note=Binds 1 [4Fe-4S] cluster. {ECO:0000255|HAMAP-Rule:MF_00159};
CC -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC phosphate: step 5/6. {ECO:0000255|HAMAP-Rule:MF_00159}.
CC -!- SIMILARITY: Belongs to the IspG family. {ECO:0000255|HAMAP-
CC Rule:MF_00159}.
