ID 4.2.3.226 DE (+)-2-epi-prezizaene synthase. CA (2Z,6E)-farnesyl diphosphate = (+)-2-epi-prezizaene + diphosphate. CC -!- The enzyme occurs in plants. CC -!- The initial cyclization product is a (7R)-beta-bisabolyl cation. CC -!- The major final product is (+)-2-epi-prezizaene. CC -!- Other products are (-)-alpha-cedrene (cf. EC 4.2.3.227), small CC amounts of (-)-beta-curcumene, and other sesquiterpenes with less CC than 10% yield. CC -!- The enzyme also catalyzes the reaction of EC 4.2.3.61. DR Q40577, 5EAS_TOBAC ; //
