Outline of Final Research Achievements

Glucose induction of sigX was shown to be mediated by an autoregulatory system including CshA, YlxR, and TsaD. CshA associates with RNA polymerase and the acetylation promotes the association. CshA-RNAP regulates ylxR and YlxR regulates tsaD. YlxR is a nonspecific DNA-binding protein that associates with chromosomes and regulates transcription of about 400 genes according to RNA-seq analysis. TsaD modifies tRNA and modified tRNA would be required for proper protein translation. Thus, tsaD was predicted to affect CshA acetylation through production of acetyl CoA by the pyruvate dehydrogenase PdhABCD. Western analysis showed that in the tsaD strain, PdhA failed to undergo normal translation and subsequent folding, and thus aggregation was observed. Hence TsaD was required for protein quqlity contro of PdhA.

Academic Significance and Societal Importance of the Research Achievements

枯草菌でのタンパク質アセチル化の制御を含む新たなグルコース反応系の普遍性が今後の課題である。YlxRは、非特異的DNA結合性と転写制御活性を持つNucleoid-associated proteinであり、多くの細菌門で保存されている。TsaEBDも、全生物界に保存されたtRNAの修飾酵素である。この酵素は真核細胞ではテロメア維持に関わることが知られており、tRNA修飾以外の機能も予想されているが、細菌では欠損による表現型すら知られていなかった。従ってTsaD欠損によりPdhABCDのタンパク質品質保持に障害が起きるという発見は、細菌でのTsaEBDの機能解明の契機となることが期待される。
