ENZYME entry: EC 2.5.1.84

Accepted Name
all-trans-nonaprenyl-diphosphate synthase [geranyl-diphosphate specific].
Alternative Name(s)
nonaprenyl diphosphate synthase.
solanesyl-diphosphate synthase.
Reaction catalysed
(2E)-geranyl diphosphate + 7 isopentenyl diphosphate <=> all-trans-nonaprenyl diphosphate + 7 diphosphate
Comment(s)
  • (2E,6E)-Farnesyl diphosphate and geranylgeranyl diphosphate are less effective as substrates than geranyl diphosphate.
  • The enzyme is involved in the synthesis of the side chain of menaquinone-9.
  • In Oryza sativa the enzyme SPS2 is involved in providing solanesyl diphosphate for plastoquinone-9 formation.
  • Formerly EC 2.5.1.11.
