(+)-camphene synthase (EC 4.2.3.116) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase (cyclizing, (+)-camphene-forming).[1][2][3][4] This enzyme catalyses the following chemical reaction

geranyl diphosphate (+)-camphene + diphosphate

Cyclase I of Salvia officinalis (sage) gives about equal parts (+)-camphene and (+)-alpha-pinene.
