ID   2.5.1.84
DE   all-trans-nonaprenyl-diphosphate synthase [geranyl-diphosphate specific].
AN   nonaprenyl diphosphate synthase.
AN   solanesyl-diphosphate synthase.
CA   (2E)-geranyl diphosphate + 7 isopentenyl diphosphate = all-trans-
CA   nonaprenyl diphosphate + 7 diphosphate.
CC   -!- (2E,6E)-Farnesyl diphosphate and geranylgeranyl diphosphate are less
CC       effective as substrates than geranyl diphosphate.
CC   -!- The enzyme is involved in the synthesis of the side chain of
CC       menaquinone-9.
CC   -!- In Oryza sativa the enzyme SPS2 is involved in providing solanesyl
CC       diphosphate for plastoquinone-9 formation.
CC   -!- Formerly EC 2.5.1.11.
