Accepted name: (E)-β-ocimene synthase
Reaction: geranyl diphosphate = (E)-β-ocimene + diphosphate
Glossary: (E)-β-ocimene = (3E)-3,7-dimethylocta-1,3,6-triene
Other name(s): β-ocimene synthase; AtTPS03; ama0a23; LjEβOS; MtEBOS
Systematic name: geranyl-diphosphate diphosphate-lyase [(E)-β-ocimene-forming]
Comments: Widely distributed in plants, which release β-ocimene when attacked by herbivorous insects.
