EC 220.127.116.11 - Valencene synthase
IntEnz Enzyme Nomenclature
- (2E,6E)-farnesyl diphosphate = (+)-valencene + diphosphate
The recombinant enzyme from Vitis vinifera gave 49.5% (+)-valencene and 35.5% (-)-7-epi-α-selinene. Initial cyclization gives (+)-germacrene A in an enzyme bound form which is not released to the medium.
