EC 4.2.3.55     
Accepted name: (S)-β-bisabolene synthase
Reaction: (2E,6E)-farnesyl diphosphate = (S)-β-bisabolene + diphosphate

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase [(S)-β-bisabolene-forming]
Comments: The synthesis of (S)-β-macrocarpene from (2E,6E)-farnesyl diphosphate proceeds in two steps. The first step is the cyclization to (S)-β-bisabolene. The second step is the isomerization to (S)-β-macrocarpene (cf. EC 5.5.1.17, (S)-β-macrocarpene synthase). The enzyme requires Mg2+ or Mn2+ for activity.
