Isopentenyl-diphosphate delta-isomerase 2
Function
Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP).
Pathway
Isoprenoid biosynthesis; dimethylallyl diphosphate biosynthesis; dimethylallyl diphosphate from isopentenyl diphosphate: step 1/1.
Sequence Similarities
Belongs to the IPP isomerase type 1 family.
Tissue Specificity
Muscle-specific expression.
Cellular localization
- Peroxisome
Alternative names
Isopentenyl-diphosphate delta-isomerase 2, Isopentenyl pyrophosphate isomerase 2, IPP isomerase 2, IPPI2, IDI2
