Pinene synthase

In enzymology, a pinene synthase (EC 4.2.3.14) is an enzyme that catalyzes the chemical reaction

Hence, this enzyme has one substrate, geranyl diphosphate, and two products, pinene and diphosphate.

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is geranyl-diphosphate diphosphate-lyase (cyclizing, pinene-forming). Other names in common use include beta-geraniolene synthase, (−)-(1S,5S)-pinene synthase, and geranyldiphosphate diphosphate lyase (pinene forming). This enzyme participates in monoterpenoid biosynthesis.
