(E)-beta-ocimene synthase (EC 4.2.3.106, beta-ocimene synthase, AtTPS03, ama0a23, LjEbetaOS, MtEBOS) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase ((E)-beta-ocimene-forming).[1][2][3][4] This enzyme catalyses the following chemical reaction

geranyl diphosphate (E)-beta-ocimene + diphosphate

This enzyme is widely distributed in plants, which release beta-ocimene when attacked by herbivorous insects.
