Description
editThis 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.[1]
