4.2.1.125 | additional information | heterologous biosynthesis of triterpenoid dammarenediol-II, the precursor of dammarane-type tetracyclic ginsenosides, in engineered Escherichia coli strain BL21(DE3) by expressing the enzyme, and coexpressing squalene synthase, squalene epoxidase, and NADPH-cytochrome P450 reductase from Saccharomyces cerevisiae, and squalene epoxidase from Methylococcus capsulatus, as well as NADPH-cytochrome P450 reductase from Arabidopsis thaliana, and thereby reconstituting the 2,3-oxidosqualene-derived triterpenoid biosynthetic pathway.
