(+)-α-pinene synthase (EC 4.2.3.121, (+)-α-pinene cyclase, cyclase I) is an enzyme with systematic name geranyl-diphosphate diphosphate-lyase [cyclizing, (+)-α-pinene-forming].[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- geranyl diphosphate [math]\displaystyle{ \rightleftharpoons }[/math] (+)-α-pinene + diphosphate
Cyclase I of Salvia officinalis (sage) gives about equal parts (+)-α-pinene and (+)-camphene.
