(R)-limonene synthase

The enzyme (R)-limonene synthase (EC 4.2.3.20) catalyzes the reversible chemical reaction


 * geranyl diphosphate $$\rightleftharpoons$$ (+)-(4R)-limonene + diphosphate.

Description
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].

The enzyme participates in monoterpenoid biosynthesis and is localized to Leucoplasts of oil gland secretory cells.
