Outline of Final Research Achievements |
Several enzymes involved in the biosynthesis of natural products, such as plant polyketide synthase and CoA-ligase, exhibit remarkable catalytic versatility and substrate promiscuity. This makes the enzymes an excellent platform for enzyme engineering and further production of structurally divergent molecules. In this study, on the basis of the X-ray crystal structures of the enzymes, we succeeded in production of chemically and structurally divergent unnatural natural products, by structure-based enzyme engineering and precursor directed biosynthesis. In addition, we succeeded in elucidation of biosynthetic machinery of complex natural products including calyculin, teleocidin, and antimycin.
