- Geneidi
- StatusUniProtKB reviewed (Swiss-Prot)
- Amino acids180 (go to sequence)
- Protein existenceInferred from homology
- Annotation score3/5
Function
function
Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP).
Catalytic activity
- isopentenyl diphosphate = dimethylallyl diphosphate
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 Mg2+ ion per subunit. The magnesium ion binds only when substrate is bound.
Note: Binds 1 Mn2+ ion per subunit.
Pathway
Isoprenoid biosynthesis; dimethylallyl diphosphate biosynthesis; dimethylallyl diphosphate from isopentenyl diphosphate: step 1/1.
