ID 4.2.3.86 DE 7-epi-alpha-selinene synthase. CA (2E,6E)-farnesyl diphosphate = (-)-7-epi-alpha-selinene + diphosphate. CC -!- The recombinant enzyme from Vitis vinifera forms 49.5% (+)-valencene CC (cf. EC 4.2.3.73) and 35.5% (-)-7-epi-alpha-selinene. CC -!- Initial cyclization gives (+)-germacrene A in an enzyme bound form CC which is not released to the medium. DR A0A385AJM6, TPS12_DICPU; Q6Q3H2, TPSVS_VITVI; //
