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:
