Research Interests (研究概要)

One of the great mysteries among the questions concerning the origin of life is how life came to utilize functional polymers. It is important to understand how amino acid-based and nucleic acid-based macromolecules, 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 using 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 with geochemists to experimentally investigate in which primitive terrestrial and extraterrestrial environments are favorable for producing active functional polymers. Our long-term goal is to develop a more universal and plausible scenario for the emergence of life-like systems.

生命の起源に関する諸問題の中でも大きな謎の一つが、どのようにして生命が機能性のポリマーを利用するようになったかという点である。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。過去には翻訳系に関わるアミノ酸のキャリアであるtRNA分子の進化に着目した研究を行ってきたが、現在は主に宇宙生物学における「生命の起源」問題を中心に扱っている。特に合成生物学的な手法を用いて、過去にありえた分子を試験管内で合成し、ハイスループットにその機能と進化実験を行っている。また地球化学の研究者達とともに、原始地球を想定した環境や氷衛星などの地球外環境において生命につながるような化学進化が進むのかを様々な分析法を用いて調べている。長期的な目標として生命システムに至るより普遍的で確からしいシナリオを描くことを目指している。
