CC   -!- FUNCTION: Isopentenyl-diphosphate delta-isomerase; part of the second
CC       module of ergosterol biosynthesis pathway that includes the middle
CC       steps of the pathway (PubMed:7744766). Idi1 catalyzes the 1,3-allylic
CC       rearrangement of isopentenyl (IPP) to its highly electrophilic allylic
CC       isomer, dimethylallyl diphosphate (DMAPP) (PubMed:7744766). The second
CC       module is carried out in the vacuole and involves the formation of
CC       farnesyl diphosphate, which is also an important intermediate in the
CC       biosynthesis of ubiquinone, dolichol, heme and prenylated proteins.
CC       Activity by the mevalonate kinase erg12 first converts mevalonate into
CC       5-phosphomevalonate. 5-phosphomevalonate is then further converted to
CC       5-diphosphomevalonate by the phosphomevalonate kinase erg8. The
CC       diphosphomevalonate decarboxylase mvd1 then produces isopentenyl
CC       diphosphate. The isopentenyl-diphosphate delta-isomerase idi1 then
CC       catalyzes the 1,3-allylic rearrangement of the homoallylic substrate
CC       isopentenyl (IPP) to its highly electrophilic allylic isomer,
CC       dimethylallyl diphosphate (DMAPP). Finally the farnesyl diphosphate
CC       synthase fps1 catalyzes the sequential condensation of isopentenyl
CC       pyrophosphate with dimethylallyl pyrophosphate, and then with the
CC       resultant geranylpyrophosphate to the ultimate product farnesyl
CC       pyrophosphate (Probable). {ECO:0000269|PubMed:7744766, ECO:0000305}.
