ñ-Bisabolene synthase (EC 4.2.3.38, bisabolene synthase) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase ((E)-ñ-bisabolene-forming).
This enzyme catalyses the following chemical reaction:
This synthase requires a divalent cation cofactor (Mg<sup>2+</sup> or, to a lesser extent, Mn<sup>2+</sup>) to neutralize the negative charge of the diphosphate leaving group.
