Outline of Final Research Achievements

mRNA encoded proteins in the same metabolic pathway but also produces a regulatory RNA. This study revealed that the TCA cycle operon mRNA of facultative aerobic bacteria, sdhCDAB-sucABCD, processes SdhX small RNA from its 3'UTR to post-transcriptionally regulate the ackA mRNA encoding acetate kinase via direct base-pairing mechanism. In addition, SdhX specifically regulates anaerobic fumarase gene fumB and unknown gene yfbV in Salmonella, while it regulates formate dehydrogenase gene fdoG and catalase gene katG in E. coli.

Academic Significance and Societal Importance of the Research Achievements

本研究は、オペロンmRNAは同じ代謝経路の酵素タンパク質をコードするだけでなく、その3’UTRから機能性RNAを生成し、他の代謝経路の遺伝子発現を転写後レベルで制御することを明らかにした。したがって、セントラルドグマにおいて単に遺伝情報の仲介役と考えられていたmRNAに新しい機能を見出し、1961年にJacobとMonodによって提唱されたオペロン説の概念を拡張することができた。
