ID 4.2.3.55 DE (S)-beta-bisabolene synthase. CA (2E,6E)-farnesyl diphosphate = (S)-beta-bisabolene + diphosphate. CC -!- The synthesis of (S)-beta-macrocarpene from (2E,6E)-farnesyl CC diphosphate proceeds in two steps. CC -!- The first step is the cyclization to (S)-beta-bisabolene. CC -!- The second step is the isomerization to (S)-beta-macrocarpene (cf. CC EC 5.5.1.17, (S)-beta-macrocarpene synthase).
