Research Interests (研究概要)

One of the greatest mysteries regarding the origin of life is how it came to utilize functional polymers. It is crucial to understand how amino acid-based and nucleic acid-based macromolecules, such as proteins and RNAs, were created and maintained through chemical evolution in a non-equilibrium system, as well as their functionality, evolvability, and heredity. Currently, we are employing various synthetic biology and analytical chemistry methods to reconstruct and analyze the properties of primitive proteins, RNAs, and their precursors through in vitro evolution experiments. We are also working on connecting a cell-free protein synthesis system with enzyme cascades to create metal cofactors and various amino acid synthesis pathway in a mixotrophic way inside the test tube. This approach will allow us to  bridge the gap between the central dogma and metabolism, an important key step toward creating a self-sustaining artificial cell. Also we are conducting computational approach such as molecular dynamics (MD) simulation to understand the precise interaction between fatty acid membrane and small molecules. Additionally, we collaborate with geochemists to experimentally investigate which primitive terrestrial and extraterrestrial environments are conducive to producing key building blocks and active functional polymers. Our long-term goal is to develop a more universal and plausible scenario for the emergence of recursive life-like system.

生命の起源に関する諸問題の中でも大きな謎の一つに、どのようにして生命が機能性のポリマーを獲得・利用するようになったのかという問いがあります。タンパク質とRNAというアミノ酸と核酸ベースの高分子がエネルギーの非平衡状態の中でどのような化学進化の過程で作られ、維持されるようになったのか、またそれらの機能、進化、遺伝性を理解することが重要であると考えています。現在我々は合成生物学と進化分子工学を駆使して原始的なタンパク質、RNAおよびそれらの前駆体の特性を再構築し分析しています。また、無細胞翻訳系を酵素反応と組み合わせることで、試験管内で鉄硫黄クラスターや様々なアミノ酸を単純な無機物と有機物から合成することに成功しています。このアプローチにより、セントラルドクマと代謝のを接続した人工細胞の作成に向けた重要な一歩を踏み出すことができました。また、分子動力学（MD）シミュレーションを用いて、脂肪酸の膜系とアミノ酸や核酸、ペプチドといった小分子の精密な相互作用とダイナミクスを理解することを目指しています。さらに地球化学者らと協力して、生命の起源研究の観点から深海熱水系近傍のCO2流体が貯留されている環境がどのように生体関連高分子の合成に寄与するのかを実験的に調べています。我々の長期的な目標として、生命のような再帰的に維持されるシステムが出現するための最も確からしいシナリオを描くことを目指しています。
