Outline of Final Research Achievements

Sigma factor is a component of RNA polymerase (RNAP), which is a central machinery for gene transcription. In bacillus subtilis we observed that transcription of one of the extracellular function sigma factor gene, sigX, is several-fold induced by glucose. We took the hypothesis that acetylation of lysine residues in RNAP may lead to change the affinity of RNAP to SigX. However, this was not verified. Instead, the experiments to search all genes required for glucose induction of sigX revealed the cshA gene and its acetylation is important for this phenomenon.CshA is known to be associated with RNAP, and thus, acetylation of CshA would change affinity of RNAP to SigX.

Academic Significance and Societal Importance of the Research Achievements

微生物は多様な機能を持ち、自然界での生態系や人体の健康にも密接な関わりがあるので、その生命活動を詳細に理解することは、微生物機能の人間生活や産業への応用を考える上で大切である。本研究では、枯草菌という昔からよく研究されてきた細菌を用いて、グルコースという栄養分が枯草菌の生理活動にどのように影響するのかという古くて新しい疑問の一端を遺伝子とタンパク質の相互作用という観点から解明した。
