geranyl-diphosphate:isopentenyl-diphosphate transtransferase (adding 7 isopentenyl units)

geranyl diphosphate + 7 isopentenyl diphosphate = 7 diphosphate + all-trans-nonaprenyl diphosphate [RN:R09250]

R09250 > R07267
Reaction

geranyl diphosphate [CPD:C00341];
isopentenyl diphosphate [CPD:C00129]

(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 [1]. In Oryza sativa the enzyme SPS2 is involved in providing solanesyl diphosphate for plastoquinone-9 formation [3].
