SYSTEMATIC NAME
IUBMB Comments
geranyl-diphosphate diphosphate-lyase [cyclizing; (-)-(4S)-limonene-forming]
A recombinant enzyme (also known as a monoterpene synthase or cyclase) from the grand fir (Abies grandis) requires Mn2+ and K+ for activity. Mg2+ is essentially ineffective as the divalent metal ion cofactor.

additional information

increase in the expression of the spearmint LS cDNA at the different leaf developmental stages is accompanied with increases in the limonene content of transgenic spike lavender lines; leaves of transgenic plants contain increased limonene contents (more than 450% increase compared to controls) that correlates with the highest transcript accumulation of the LS gene.; the effect of the LS expression on oil composition decreases with leaf age as compared to the control; transgenic T0 spike lavender lines overexpressing MsLS show quantitative and qualitative alterations in their terpene profiles, particularly increased amounts of limonene as compared to controls (from 19.05% to 53.97% and from 12.50% to 83.33% in pooled leaves and flowers, respectively). The levels of other monoterpene pathway components are not consistently altered in either leaf or flower oils

LITERATURE
Agrobacterium-mediated transformation and regeneration of spike lavender is carried out and the transgenic Lavandula latifolia plants express the limonene synthase gene from Mentha spicata. Expression of limonene synthase in transgenic spike lavender results in an altered monoterpene composition in developing leaves, but does not consistently affect essential oil profile in pooled leaves and flowers of transgenic generation T0.

synthesis
-
engineering of Echerichia coli with a heterologous mevalonate pathway and limonene synthase for production of limonene followed by coupling with a cytochrome P450,which specifically hydroxylates limonene to produce perillyl alcohol. A strain containing all mevalonate pathway genes in a single plasmid produces limonene at titers over 400 mg/l from glucose. Incorporation of a cytochrome P450 to hydroxylate limonene yields approximately 100mg/l of perilyl alcohol
