IntEnz Enzyme Nomenclature


Accepted name:
7-epi-α-selinene synthase
Systematic name:
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (7-epi-α-selinene-forming)



The recombinant enzyme from Vitis vinifera forms 49.5% (+)-valencene (cf. EC, valencene synthase) and 35.5% (-)-7-epi-α-selinene. Initial cyclization gives (+)-germacrene A in an enzyme bound form which is not released to the medium.
