CC   -!- FUNCTION: Catalyzes the 1,3-allylic rearrangement of the homoallylic
CC       substrate isopentenyl (IPP) to its highly electrophilic allylic isomer,
CC       dimethylallyl diphosphate (DMAPP). {ECO:0000255|HAMAP-Rule:MF_00202}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=isopentenyl diphosphate = dimethylallyl diphosphate;
CC         Xref=Rhea:RHEA:23284, ChEBI:CHEBI:57623, ChEBI:CHEBI:128769;
CC         EC=5.3.3.2; Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC       Note=Binds 1 Mg(2+) ion per subunit. The magnesium ion binds only when
CC       substrate is bound. {ECO:0000255|HAMAP-Rule:MF_00202};
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00202};
CC       Note=Binds 1 Mn(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00202};
CC   -!- PATHWAY: Isoprenoid biosynthesis; dimethylallyl diphosphate
CC       biosynthesis; dimethylallyl diphosphate from isopentenyl diphosphate:
CC       step 1/1. {ECO:0000255|HAMAP-Rule:MF_00202}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00202}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00202}.
CC   -!- SIMILARITY: Belongs to the IPP isomerase type 1 family.
CC       {ECO:0000255|HAMAP-Rule:MF_00202}.
