(R)-limonene synthase explained
(R)-limonene synthase should not be confused with (4S)-limonene synthase.
| (R)-limonene synthase |
| Ec Number: | 4.2.3.20 |
The enzyme (R)-limonene synthase (EC 4.2.3.20) catalyzes the reversible chemical reaction
(+)-(4
R)-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, (+)-(4''R'')-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]
