Hexaprenyl-diphosphate synthase ((2E,6E)-farnesyl-diphosphate specific) (EC 2.5.1.83, HexPS, hexaprenyl pyrophosphate synthetase, hexaprenyl diphosphate synthase) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate:isopentenyl-diphosphate farnesyltranstransferase (adding 3 isopentenyl units).[1][2][3] This enzyme catalyses the following chemical reaction
- (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.
