Other name(s): TPS3

Systematic name: geranyl-diphosphate diphosphate-lyase (cyclizing; tricyclene-forming)

Comments: The enzyme from Solanum lycopersicum (tomato) gives a mixture of tricyclene, camphene, β-myrcene, limonene, and traces of several other monoterpenoids. See EC (–)-camphene synthase, EC, myrcene synthase and EC, (4S)-limonene synthase.
