| FUNCTION | Involved in the biosynthesis of isoprenoids. Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its allylic isomer, dimethylallyl diphosphate (DMAPP). |
| CATALYTIC ACTIVITY | Reaction=isopentenyl diphosphate = dimethylallyl diphosphate; Xref=Rhea:RHEA:23284, ChEBI:CHEBI:57623, ChEBI:CHEBI:128769; EC=5.3.3.2; |
| COFACTOR | Name=FMN; Xref=ChEBI:CHEBI:58210; |
| COFACTOR | Name=NADPH; Xref=ChEBI:CHEBI:57783; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
| SUBUNIT | Homooctamer. Dimer of tetramers. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the IPP isomerase type 2 family. |
