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