Beta-selinene cyclase

β-Selinene cyclase (EC 4.2.3.66) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase (β-selinene-forming). This enzyme catalyses the following chemical reaction


 * (2E,6E)-farnesyl diphosphate $$\rightleftharpoons$$ β-selinene + diphosphate

Initial cyclization gives (+)-germacrene A in an enzyme-bound form.
