description | <i>Ganoderma lucidum</i> is a medicinal fungus abundant in triterpenoids, its primary bioactive components. Although numerous <i>Ganoderma</i> triterpenoids have already been identified, rare <i>Ganoderma</i> triterpenoid saponins were recently discovered. To create novel <i>Ganoderma</i> saponins, ganoderic acid G (GAG) was selected for biotransformation using four <i>Bacillus</i> glycosyltransferases (GTs) including BtGT_16345 from the <i>Bacillus thuringiensis</i> GA A07 strain and three GTs (BsGT110, BsUGT398, and BsUGT489) from the <i>Bacillus subtilis</i> ATCC 6633 strain. The results showed that BsUGT489 catalyzed the glycosylation of GAG to GAG-3-<i><span style="font-variant: small-caps;">o</span></i>-<i>β</i>-glucoside, while BsGT110 catalyzed the glycosylation of GAG to GAG-26-<i><span style="font-variant: small-caps;">o</span></i>-<i>β</i>-glucoside, which showed 54-fold and 97-fold greater aqueous solubility than that of GAG, respectively. To our knowledge, these two GAG saponins are new compounds. The glycosylation specificity of the four <i>Bacillus</i> GTs highlights the possibility of novel <i>Ganoderma</i> triterpenoid saponin production in the future. |
