Outline of Final Research Achievements

The purpose of this study was to develop a stable secondary metabolite production system in heterologous expression of exogenous gene cluster for secondary metabolite biosynthesis derived from heterogenous microorganisms using an engineered Stretomyces avermitilis as a host. In this study, we developed an efficient method to introduce a large gene cluster for secondary metabolite biosynthesis. In addition, we developed an experimental method for stable retention of the introduced gene cluster in cells, a multiple gene introduction system and a combinatorial biosynthesis by the multiple gene introduction system.

Academic Significance and Societal Importance of the Research Achievements

S.avermitilis は認定宿主として登録されており、大腸菌などと同様に取り扱うことが可能である。本菌は現在も抗生物質生産のために利用されており、その様な産業微生物を二次代謝産物生産の為の包括的な異種発現宿主として利用する試みは成されていない。遺伝的な背景および遺伝子導入系が整備されていない生産菌の保有する二次代謝産物について、本研究によって得られる成果により、その生合成遺伝子群を汎用宿主に導入すれば、生産過程の包括的な解析の展開が可能となる。さらに、これまで遺伝的な不安定性あるいは分子遺伝学的な基盤の整備が乏しくて解析が断念された多くの二次代謝産物についても適用が期待できる。
