Glossary: 5-epi-α-selinene = 5β-eudesma-3,11-diene = (2R,4aR,8aS)-1,2,3,4,4a,5,6,8a-octahydro-4a,8-dimethyl-2-(prop-1-en-2-yl)naphthalene;;
[= 8a-epi-α-selinene which uses naththalene numbering not eudesmane]

Other name(s): 8a-epi-α-selinene synthase; NP1

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, 5-epi-α-selinene-forming)

Comments: Requires Mg2+. The enzyme forms 5-epi-α-selinene possibly via germecrene A or a 1,6-hydride shift mechanism.
