In [[enzymology]], a '''pinene synthase''' ({{EC number|4.2.3.14}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:geranyl diphosphate <math>\rightleftharpoons</math> pinene + diphosphate

Hence, this enzyme has one [[substrate (biochemistry)|substrate]], [[geranyl diphosphate]], and two [[product (chemistry)|products]], [[pinene]] and [[diphosphate]].

This enzyme belongs to the family of [[lyase]]s, 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]].
