All-trans-octaprenyl-diphosphate synthase (EC 2.5.1.90, octaprenyl-diphosphate synthase, octaprenyl pyrophosphate synthetase, polyprenylpyrophosphate synthetase, terpenoidallyltransferase, terpenyl pyrophosphate synthetase, trans-heptaprenyltranstransferase, trans-prenyltransferase) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate:isopentenyl-diphosphate farnesyltranstransferase (adding 5 isopentenyl units).[1][2] This enzyme catalyses the following chemical reaction

(2E,6E)-farnesyl diphosphate 5 isopentenyl diphosphate 5 diphosphate all-trans-octaprenyl diphosphate

This enzyme catalyses the condensation reactions resulting in the formation of all-trans-octaprenyl diphosphate.
