In enzymology, a (R)-limonene synthase (EC 4.2.3.20) is an enzyme that catalyzes the chemical reaction

geranyl diphosphate \rightleftharpoons (+)-(4R)-limonene + diphosphate

Hence, this enzyme has one substrate, geranyl diphosphate, and two products, (+)-(4R)-limonene 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, (+)-(4R)-limonene-forming]. Other names in common use include (+)-limonene synthase, and geranyldiphosphate diphosphate lyase [(+)-(R)-limonene-forming]. This enzyme participates in monoterpenoid biosynthesis.
