SYSTEMATIC NAME
IUBMB Comments
geranyl-diphosphate diphosphate-lyase (cyclizing; tricyclene-forming)
The enzyme from Solanum lycopersicum (tomato) gives a mixture of tricyclene, camphene, beta-myrcene, limonene, and traces of several other monoterpenoids. See EC 4.2.3.117. (-)-camphene synthase, EC 4.2.3.15, myrcene synthase and EC 4.2.3.16, (4S)-limonene synthase.
