(-)-camphene synthase

(–)-camphene synthase (EC 4.2.3.117, CS) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase [cyclizing, (–)-camphene-forming].[1][2][3][4] This enzyme catalyses the following chemical reaction

\rightleftharpoons

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