We are developing biomacromolecules that control enzymes and cells.

Research Summary

We are engineering functional biomacromolecules applicable to medical and basic researches, by integrating technologies in synthetic and structural biology including peptide/RNA in vitro evolution, X-ray crystallography, etc. Utilizing the same technologies, we are also trying to reconstruct the evolutional pathway of primordial proteins.

Research Theme

  • We are engineering peptides that control cells and enzymes for use in medical and basic science.
  • We are trying to experimentally reconstruct evolutional pathway from primordial peptides to elaborate proteins.
