(−)-camphene synthase

(−)-camphene synthase (EC 4.2.3.117, CS) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase [cyclizing, (−)-camphene-forming]. This enzyme catalyses the following chemical reaction


 * geranyl diphosphate $$\rightleftharpoons$$ (−)-camphene + diphosphate

(−)-Camphene is the major product in Abies grandis (grand fir) with traces of other monoterpenoids.
