Accepted name: terpinolene synthase
Reaction: geranyl diphosphate = terpinolene + diphosphate
For diagram of menthane monoterpenoid biosynthesis, click here
Glossary: terpinolene = 1-methyl-4-(propan-2-ylidene)cyclohexene
Other name(s): ag9; PmeTPS2; LaLIMS_RR
Systematic name: geranyl-diphosphate diphosphate-lyase (cyclizing, terpinolene-forming)
Comments: Requires Mg2+. Mn2+ is less effective and product ratio changes. Forms traces of other monoterpenoids.
