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:0000255|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       biosynthesis; dimethylallyl diphosphate from (2E)-4-hydroxy-3-
CC       methylbutenyl diphosphate: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00191}.
CC   -!- PATHWAY: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis
CC       via DXP pathway; isopentenyl diphosphate from 1-deoxy-D-xylulose 5-
CC       phosphate: step 6/6. {ECO:0000255|HAMAP-Rule:MF_00191}.
