(4S)-limonene synthase

In enzymology, a (4S)-limonene synthase is an enzyme that catalyzes the chemical reaction


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

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