EC 4.2.3.143

Accepted name: kunzeaol synthase

Reaction: (2E,6E)-farnesyl diphosphate + H2O = kunzeaol + diphosphate

Glossary: kunzeaol = 6β-hydroxygermacra-1(10),4-diene = (1R,2E,6E,10R)-3,7-dimethyl-10-isopropylcyclodeca-2,6-dienol

Other name(s): TgTPS2 (gene name)

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (kunzeaol forming)

Comments: Isolated from the root of the plant Thapsia garganica. The enzyme also produces germacrene D, bicyclogermacrene and traces of other sesquiterpenoids. See EC 4.2.3.77, (+)-germacrene D synthase and EC 4.2.3.100, bicyclogermacrene synthase.
