CC -!- FUNCTION: Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl
CC 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP)
CC and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the
CC DOXP/MEP pathway for isoprenoid precursor biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_00191}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + isopentenyl diphosphate + 2 oxidized [2Fe-2S]-
CC [ferredoxin] = (2E)-4-hydroxy-3-methylbut-2-enyl diphosphate + 2 H(+)
CC + 2 reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:24488, Rhea:RHEA-

CC Note=Binds 1 [4Fe-4S] cluster per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00191};
CC -!- PATHWAY: Isoprenoid biosynthesis; dimethylallyl diphosphate
CC biosynthesis; dimethylallyl diphosphate from (2E)-4-hydroxy-3-
CC methylbutenyl diphosphate: step 1/1. {ECO:0000256|HAMAP-Rule:MF_00191}.
