Isopentenyl-diphosphate Delta-isomerase 2 (IDI2) is a member of the IPP isomerase type 1 family. IDI2 catalyzes the 1,3-allylic reorganization of the homoallylic substrate isopentenyl (IPP) to its extremely electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP).
IDI2 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 247 amino acids (1-227 a.a.) and having a molecular mass of 28.9kDa.
IDI2 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
