Abstrakt: In this work, we developed a novel strategy, prior disulfide bond-mediated Ser/Thr ligation (PD-STL), for the chemical synthesis of peptides and proteins. This approach combines disulfide bond-forming chemistry with Ser/Thr ligation (STL), converting intermolecular STL into intramolecular STL to effectively proceed regardless of concentrations. We demonstrated the effectiveness of PD-STL under high dilution conditions, even for the relatively inert C-terminal proline at the ligation site. Additionally, we applied this method to synthesize the N-terminal cytoplasmic domain (2-104) of caveolin-1 and its Tyr14 phosphorylated form.
