Isopentenyl pyrophosphate rearranges to dimethylallyl pyrophosphate Authored: Jassal, B, 2007-01-24 15:15:12 Cytosolic isopentenyl diphosphate isomerase (IPP isomerase) catalyzes an essential activation step in the isoprenoid biosynthetic pathway. It rearranges isopentenyl pyrophosphate into its highly electrophilic isomer, dimethylallyl pyrophosphate (DMAPP). IPP isomerase may also be located in human peroxisomes but it's function there is not clear.
