EC 4.2.3.98     
Accepted name: (+)-T-muurolol synthase
Reaction: (2E,6E)-farnesyl diphosphate + H2O = (+)-T-muurolol + diphosphate

Glossary: (+)-T-muurolol = (1R,4R,4aS,8aR)-1,6-dimethyl-4-(propan-2-yl)-1,2,3,4,4a,7,8,8a-octahydronaphthalen-1-ol
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, (+)-T-muurolol-forming)
Comments: The cyclization mechanism involves an intermediate nerolidyl diphosphate leading to a helminthogermacradienyl cation. After a 1,3-hydride shift of the original 1-pro-S hydrogen of farnesyl diphosphate, cyclization and deprotonation result in (+)-T-muurolol.
