Outline of Final Research Achievements |
All of the > 30,000 trierpenoinds are synthesized via squalene. To start accessing those structurally and functionally diverse compounds, we have developed a novel screening system to visualize squalene consumption. By using this as a screening principle, we have identified activity mutants of squalene cyclizing enzymes, enabling efficient microbial synthesis of cyclic triterpenoids. By combining these mutant enzymes with pathways for squalene-like molecules, we succeeded in establishing pathways toward numbers of novel compounds that have not been previously reported.
