EC 4.2.3.58     
Accepted name: longifolene synthase
Reaction: (2E,6E)-farnesyl diphosphate = longifolene + diphosphate
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (longifolene-forming)
Comments: As well as 61% longifolene the enzyme gives 15% of α-longipinene, 6% longicyclene and traces of other sesquiterpenoids.
