摘要: The Pictet-Spenglerase strictosidine synthase (STR) has been characterized
as the central enzyme in the biosynthesis of around 2000 monoterpenoid indole alkaloids
in plants. In the light of a high therapeutic value and huge scaffold diversity these
alkaloids represent, STR as an enzyme has attracted great attentions in recent years, intending to be utilized in the formation
of new interesting alkaloids with unusual substitution pattern or even with novel scaffolds. For outlining the application
potential that STR possesses, together with insight into the reaction mechanism catalyzed by STR, strategies and
methods for exploring the applicability of STR have been updated in this article by taking R. serpentina STR (RS-STR)
and C. roseus. STR (CR-STR) as representative models, followed by introducing the latest released complex structures of
RS-STR with new substrates. Examples provided here, including substrate scaffold tailoring, X-ray crystal complex structure
comparison, protein engineering and biosynthetic pathway reprogramming, pave the way to finally construct novel
alkaloids libraries by chemo-enzymatic approaches.
