ENZYME entry: EC 2.5.1.30

Accepted Name
heptaprenyl diphosphate synthase
Alternative Name(s)
all-trans-heptaprenyl-diphosphate synthase
HepPP synthase
heptaprenyl pyrophosphate synthetase
trans-hexaprenyltranstransferase
Reaction catalysed
(2E,6E)-farnesyl diphosphate + 4 isopentenyl diphosphate <=> all-trans-heptaprenyl diphosphate + 4 diphosphate
Comment(s)
  • This enzyme catalyzes the condensation reactions resulting in the formation of all-trans-heptaprenyl diphosphate, the isoprenoid side chain of ubiquinone-7 and menaquinone-7.
  • The enzyme adds four isopentenyl diphosphate molecules sequentially to farnesyl diphosphate with trans stereochemistry.
