geranyl-diphosphate diphosphate-lyase [cyclizing, (-)-camphene-forming]

geranyl diphosphate = (-)-camphene + diphosphate [RN:R09972]

geranyl diphosphate [CPD:C00341]

(-)-Camphene is the major product in Abies grandis (grand fir) with traces of other monoterpenoids [1]. In Pseudotsuga menziesii (Douglas-fir) there are about equal parts of (-)-camphene and (-)-alpha-pinene with traces of four other monoterpenoids [2,3]. In Solanum lycopersicum (tomato) tricyclene, beta-myrcene, limonene, and traces of several other monoterpenoids are also formed [4]. See also EC 4.2.3.15 myrcene synthase, EC 4.2.3.16 (4S)-limonene synthase, EC 4.2.3.119 (-)-alpha-pinene synthase and EC 4.2.3.105 tricyclene synthase.
