ID   2.5.1.82
DE   hexaprenyl diphosphate synthase [geranylgeranyl-diphosphate specific].
AN   (all-trans)-hexaprenyl-diphosphate synthase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate + 2 isopentenyl diphosphate = all-
CA   trans-hexaprenyl diphosphate + 2 diphosphate.
CC   -!- The enzyme prefers geranylgeranyl diphosphate to farnesyl diphosphate
CC       as an allylic substrate and does not show activity for geranyl
CC       diphosphate and prenyl diphosphate.
CC   -!- Formerly EC 2.5.1.33.
