vernolic acid/euphorbia

Two oxygenases associated with microsomes prepared from Euphorbia lagascae developing seeds were found to convert linoleic acid into cis-12,13-epoxy-9(Z)-octadecenoic acid (vernolate): a cytochrome P-450 and a peroxygenase. The cytochrome P-450 dependent epoxidation is characterized by a remarkable

The endosperm of Euphorbia lagascae Spreng. seeds contains high levels of the epoxidated fatty acid vernolic acid ( cis-12-epoxyoctadeca-cis-9-enoic acid). To obtain transgenic oilcrops producing high levels of vernolic acid, better knowledge of its endogenous metabolism is needed. In this paper we

In Euphorbia lagascae the major fatty acid in triacylglycerol is the epoxidated fatty acid vernolic acid (cis-12-epoxyoctadeca-cis-9-enoic acid). The enzymic reactions occurring during the catabolism of epoxidated fatty acids during germination are not known, but it seems likely that the degradation

Epoxidated fatty acids are the major constituents of the triacylglycerols in a few plant species. We have investigated the biosynthesis of vernolic acid (cis-12-epoxyoctadeca-cis-9-enoic acid) in the seed oil of Euphorbia lagascae. Microsomes were isolated from developing endosperm. The membrane

Seed oils of a number of Asteraceae and Euphorbiaceae species are enriched in 12-epoxyoctadeca-cis-9-enoic acid (vernolic acid), an unusual 18-carbon Delta(12)-epoxy fatty acid with potential industrial value. It has been previously demonstrated that the epoxy group of vernolic acid is synthesized

Sterol carrier protein-2 (SCP-2) is a small intracellular basic protein domain implicated in peroxisomal beta-oxidation. We extend our knowledge of plant SCP-2 by characterizing SCP-2 from Euphorbia lagascae. This protein consists of 122 amino acids including a PTS1 peroxisomal targeting signal. It

The endosperm of Euphorbia lagascae Spreng. seeds contains high levels of the epoxidated fatty acid vernolic acid [12(S),13(R)-epoxy-12-octadecenoic acid]. To learn more about the function and metabolism of vernolic acid, we have initiated an investigation into the gene activities involved in the
