NATIVE CHEMICAL LIGATION AT SERINE AND THREONINE SITES
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 (a)): a) reacting the starting peptide(s) to form an acetal intermediate with an acetal group at the ligation site; b) converting said acetal intermediate to a desired peptide or protein with said natural peptide bond.
