Outline of Research at the Start

微生物は発酵生産過程において、過酷な環境変化に曝される。微生物に環境耐性を付与して有用物質を大量生産させるには、環境変化に対する応答機構(代謝制御、遺伝子発現制御など)を明らかにする必要がある。代謝制御の仕組みとして、代謝酵素のアロステリック制御、フィードバック・フィードフォワード制御などが研究されてきた。分子生物学の発展以降、代謝酵素の転写・翻訳レベルの制御も明らかにされてきた。近年、ユビキチン修飾系による代謝制御の報告が続いているが、これらは氷山の一角に過ぎない。本研究では、ユビキチン修飾を介した代謝の環境応答機構を明らかにすることで、微生物の代謝改変法の開発に寄与する基盤的研究を行う。

Outline of Final Research Achievements

Microorganisms are exposed to severe environmental changes during fermentation and production process. In order to make microorganisms tolerant to environmental changes and fermentation processes, it is necessary to elucidate the response mechanisms (metabolic regulation, gene expression regulation, etc.) to environmental changes. In this study, we aimed to elucidate a new environmental response mechanism of the carbon metabolism system via ubiquitin modification in budding yeast. We reported the regulatory mechanism of the triacylglycerol lipase during the cell cycle and the mechanism that fine-tunes ribosome biosynthesis under starvation conditions.

Academic Significance and Societal Importance of the Research Achievements

微生物は自然界において、温度、凍結、乾燥、化学物質、浸透圧、pH、低栄養、異常タンパク質蓄積など、多様なストレスに曝されている。このようなストレスや環境の変化に対して、微生物は遺伝子発現、タンパク質間相互作用、酵素活性、代謝経路などを制御することで、巧みに適応している。しかし、発酵食品、バイオ燃料、アミノ酸、酵素など、有用物質を工業的に大量生産させる過程では、細胞の増殖が阻害され、死に至るような環境変化に曝されることがありえる。本研究では、環境変化に対する応答機構を解明して、工業的に有利な環境耐性を備えた微生物の創出を目指そうとする点に学術的意義と社会的意義がある。
