| Outline of Final Research Achievements |
Novel polypeptides containing a zwitterionic structure similar to ionic liquids, which dissolve cellulose crystals, were designed and synthesized by chemoenzymatic polymerization using enzymes. The aqueous solution of the zwitterionic polypeptides effectively dissociated the bundle of cellulose nanocrystals. It was found that the cellulose network in the cell walls of cultured plant cells was dissociated by treatment with the zwitterionic polypeptides.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発されたzwitterion型ポリペプチドは、不溶不融で成型加工性に乏しいセルロースの結晶を効果的に解離することが可能であり、セルロースの化学構造を改変することなく簡便に加工する技術として産業的に有用性が高い。また、細胞毒性をほとんど示さずに植物細胞壁のセルロースネットワークを緩めることができ、植物細胞への効率的な物質輸送など植物科学分野への応用も期待できる。
