| Outline of Final Research Achievements |
A stimulus-responsive amino acid, which induces stimulus-triggered amide/peptide bond cleavage, enables functional control of peptides and proteins. In this project, we challenged to accelerate the amide bond cleavage of the stimulus-responsive unit that should be the bases for practical stimulus-responsive amino acids. We first established a fluorescence-based system to easily monitor the amide bond cleavage. Then, several new stimulus-responsive units were synthesized and their kinetics of the amide bond cleavage was evaluated based on the fluorescence monitoring. Finally, we successfully found out a new stimulus-responsive unit, its amide bond cleavage is significantly accelerated under acid conditions.
