| Research Abstract |
The peptide thioester is used as a building block for protein synthesis. In this research, we developed new methods for the peptide thioester synthesis. Based on the structure of Cys-Pro ester(CPE), Cys-Pro-Cys sequence was found to produce a peptide thioester. It could be prepared as a recombinant protein. When N-substitute Gly residue is introduced instead of the Pro residue in the CPE structure, this CNGE peptide produces the thioester more efficiently than the CPE peptide.
