Other name(s): |
8-epicedrol synthase; epicedrol synthase |
Systematic name: |
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (8-epi-cedrol-forming) |
Comments: |
The enzyme is activated by Mg2+ [2]. Similar to many other plant terpenoid synthases, this enzyme produces many products from a single substrate. The predominant product is the cyclic sesquiterpenoid alcohol, 8-epi-cedrol, with minor products including cedrol and the olefins α-cedrene, β-cedrene, (E)-β-farnesene and (E)-α-bisabolene [1]. |
