(âÂÂ)-ò-Pinene synthase (EC 4.2.3.120, ò-geraniolene synthase, (âÂÂ)-(1S,5S)-pinene synthase, geranyldiphosphate diphosphate lyase (pinene forming)) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase [cyclizing, (âÂÂ)-ò-pinene-forming]. This enzyme catalyses the following chemical reaction
Cyclase II of Salvia officinalis (sage) produces about equal parts (âÂÂ)-ñ-pinene, (âÂÂ)-ò-pinene and (âÂÂ)-camphene.
