A chemoselective chemical ligation method is disclosed. The method joins two peptide segments efficiently to produce a larger peptide or protein, by generating a natural peptide bond (Xaa-Ser and Xaa-Thr) at the ligation site (Xaa represents any 5 amino acid). The method requires two steps (Fig. 1 (.....
