| Research Abstract |
Polyketide synthases (PKSs) are important enzymes involved in the construction of basic carbon skeletons of polyketides. In this study, structure and reaction control mechanisms by iterative type I PKSs were investigated. On the 6-methylsalicylic acid synthase, a new catalytic domain named "Thioester Hydrolase" domain was identified which is involved in the product release. In addition, new aspects on the reaction control mechanisms of non-reducing type I PKSs, reducing type I PKSs, and PKS-NRPS (non-ribosomal peptide synthase) were identified.
