(−)-beta-pinene synthase

(−)-β-Pinene synthase (EC 4.2.3.120, β-geraniolene synthase, (−)-(1S,5S)-pinene synthase, geranyldiphosphate diphosphate lyase (pinene forming)) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase [cyclizing, (−)-β-pinene-forming]. This enzyme catalyses the following chemical reaction


 * geranyl diphosphate $$\rightleftharpoons$$ (−)-β-pinene + diphosphate

Cyclase II of Salvia officinalis (sage) produces about equal parts (−)-α-pinene, (−)-β-pinene and (−)-camphene.
