ID 4.2.3.188 DE beta-geranylfarnesene synthase. CA (1) (2E,6E,10E,14E)-geranylfarnesyl diphosphate = beta-geranylfarnesene + CA diphosphate. CA (2) all-trans-hexaprenyl diphosphate = beta-hexaprene + diphosphate. CA (3) all-trans-heptaprenyl diphosphate = beta-heptaprene + diphosphate. CC -!- Isolated from the bacterium Bacillus clausii. CC -!- The enzyme acts on a range of polyprenyl diphosphates. DR M5AW86, BCLTS_SHOCL; //
