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
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
OBJECTIVE
To optimize the synthetic pathway and fermentation process of yeast cell factories for production of oleanoic acid.
METHODS
Using the DNA assembler method, one copy of Glycyrrhiza glabra beta-amyrin synthase (GgbAS), Medicago truncatula oleanolic acid synthase (MtOAS) and Arabidopsis
