... N.,Ikeshiro, Y. , Kushiro, T., Shibuya, M. & Ebizuka, Y. (2001)Cloning and characterization of a cDNA encoding b-amyrinsynthase involved in glycyrrhizin and soyasaponin biosynthesis in licorice. ... useful toolnot only for elucidating bryonolic acid biosynthesis in cultured Luffa cells, but also for studying the regulation of the branch point in triterpenoid biosynthesis to supplydiverse ... b-amyrinsynthase. In this study, we used the Glycyrrhiza glabraGgbAS1 b-amyrin synthase cDNA [6] to isolate cDNA for anew OSC family member from the Luffa cDNA library byheterologous hybridization....
