CC -!- FUNCTION: Involved in the biosynthesis of isoprenoids. Catalyzes the
CC 1,3-allylic rearrangement of the homoallylic substrate isopentenyl
CC (IPP) to its allylic isomer, dimethylallyl diphosphate (DMAPP).
CC {ECO:0000255|HAMAP-Rule:MF_00354}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=isopentenyl diphosphate = dimethylallyl diphosphate;
CC Xref=Rhea:RHEA:23284, ChEBI:CHEBI:57623, ChEBI:CHEBI:128769;

CC Evidence={ECO:0000255|HAMAP-Rule:MF_00354};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00354};
CC -!- SUBUNIT: Homooctamer. Dimer of tetramers. {ECO:0000255|HAMAP-
CC Rule:MF_00354}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00354}.
CC -!- SIMILARITY: Belongs to the IPP isomerase type 2 family.
CC {ECO:0000255|HAMAP-Rule:MF_00354}.
