| Outline of Final Research Achievements |
Complex polyether natural products are constructed by epoxidations followed by cyclizations as exemplified by Cane, Celmer and Westley. Two key enzymes, epoxidase and epoxide hydrolase, are involved in the highly regioselective and stereoselective reactions. To elucidate the function of those enzymes, we conducted in vitro (or in vivo) analysis utilizing substrate analogs and figure out the regulation mechanism in part. Additionally, we achieved chemoenzymatic synthesis of oxasqualenoid by utilizing functionally characterized EPX. These findings open the door for the enzymatic synthesis of polyether skeleton.
