From Wikipedia, the free encyclopedia
(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
⇌
{\displaystyle \rightleftharpoons }
(E )-β-ocimene +
diphosphate
This enzyme is widely distributed in
plants , which release β-ocimene when attacked by herbivorous
insects .
