Enzyme Information
| 2.5.1.83 |
Hexaprenyl-diphosphate synthase ((2E,6E)-farnesyl-diphosphate specific).
based on mapping to UniProt O66127
(2E,6E)-farnesyl diphosphate + 3 isopentenyl diphosphate = 3 diphosphate + all-trans-hexaprenyl diphosphate.
-!- The enzyme prefers farnesyl diphosphate to geranylgeranyl diphosphate as an allylic substrate and does not show activity for geranyl diphosphate and dimethylallyl diphosphate. -!- Formerly EC 2.5.1.33.
