A vast array of triterpenes are found in living organisms in addition to lanosterol and cycloartenol, which are involved in sterol biosynthesis in non-photosynthetic and photosynthetic eukaryotes respectively. The chemical structure of these triterpenes is determined by a single step catalysed by

UNASSIGNED The purpose of this study was to determine if Arabidopsis protoplast transfection could be scaled up, from the commonly used cell-based studies, to be used in triterpenoid production assays as an in planta alternative/complement to other expression systems. Enzyme activities are often

Triterpenoids produced by plants play important roles in the protection against biotic stress. Roots of Arabidopsis thaliana produce different triterpenoids, which include the tricyclic triterpene diol, arabidiol. In a degradation reaction induced by infection with the oomycete pathogen, Pythium

OBJECTIVE To achieve heterologous biosynthesis of dammarenediol-II, which is the precursor of dammarane-type tetracyclic ginsenosides, by reconstituting the 2,3-oxidosqualene-derived triterpenoid biosynthetic pathway in Escherichia coli. RESULTS By the strategy of synthetic biology, dammarenediol-II

BACKGROUND Sequencing of the first plant genomes has revealed that cytochromes P450 have evolved to become the largest family of enzymes in secondary metabolism. The proportion of P450 enzymes with characterized biochemical function(s) is however very small. If P450 diversification mirrors evolution

We report the structure determination of 20,29,30-trinorlup-18-en-3beta-ol (trinorlupeol) and establish this novel C 27 metabolite as a major nonsterol triterpenoid in Arabidopsis thaliana. Trinorlupeol was concentrated in cuticular waxes, notably in the plant stem, floral buds, and seedpods, but

Catharanthus roseus is an important medicinal plant and the sole commercial source of monoterpenoid indole alkaloids (MIA), anticancer compounds. Recently, triterpenoids like ursolic acid and oleanolic acid have also been found in considerable amounts in C. roseus leaf cuticular wax layer. These

Triterpenoids have diverse chemical structures and bioactivities. Cytochrome P450 monooxygenases play a key role in their structural diversification. In higher plants, CYP716A subfamily enzymes are triterpene oxidases. In this study, Arabidopsis thaliana CYP716A1 and CYP716A2 were characterized by

Insights into the functional properties of the marneral oxidase CYP71A16 from Arabidopsis thaliana.

The Arabidopsis thaliana gene encoding CYP71A16 is part of the gene cluster for the biosynthesis and modification of the triterpenoid marneral. Previous investigations of A. thaliana have revealed that CYP71A16 catalyzes marneral oxidation, while it also can accept marnerol as substrate. The aim of

Triterpenoid saponins are naturally occurring structurally diverse glycosides of triterpenes that are widely distributed among plant species. Great interest has been expressed by pharmaceutical and agriculture industries for the glycosylation of triterpenes. Such modifications alter their taste and

Genome mining to identify new plant triterpenoids.

Arabidopsis thaliana is a well-established model organism for plant genetics, and its recently sequenced genome reveals a wealth of enzymes similar to known examples that biosynthesize secondary metabolites. We describe experiments that exploit this genomic information to identify novel terpenoids.

Squalene epoxidase converts squalene into oxidosqualene, the precursor of all known angiosperm cyclic triterpenoids, which include membrane sterols, brassinosteroid phytohormones, and non-steroidal triterpenoids. In this work, we have identified six putative Arabidopsis squalene epoxidase (SQE)

Sesquiterpenes are an abundant group belonging to the terpenoid family, with a C15 structure comprise of three isoprene units. Many sesquiterpenes are volatile compounds and it act as chemical messenger in plant signalling, particularly in the defense mechanism against biotic and abiotic stresses.

Betulinic acid is a product of plant secondary metabolism which has shown various bioactivities. Several CYP716A subfamily genes were recently characterized encoding multifunctional oxidases capable of C-28 oxidation. CYP716A12 was identified as betulin C-28 oxidase, capable of modifying betulin.

UDP-glycosyltransferases from the UGT73C subfamily in Barbarea vulgaris catalyze sapogenin 3-O-glucosylation in saponin-mediated insect resistance.

Triterpenoid saponins are bioactive metabolites that have evolved recurrently in plants, presumably for defense. Their biosynthesis is poorly understood, as is the relationship between bioactivity and structure. Barbarea vulgaris is the only crucifer known to produce saponins. Hederagenin and
