Comments [?]

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 RHEA:23284: isopentenyl diphosphate = dimethylallyl diphosphate
EC 5.3.3.2
Cofactor FMN
NADPH
Mg(2+)
Subunit Homooctamer. Dimer of tetramers.
Subcellular location Cytoplasm.
Similarity Belongs to the IPP isomerase type 2 family.
