Synthesis

The protein human CCL2 has been synthesized using a combination of solid phase peptide synthesis (SPPS) and native chemical ligation (NCL). The thioester-peptide segment was synthesized using the sulfonamide safety-catch linker and 9-fluorenylmethoxycarbonyl (Fmoc) SPPS, and pseudoproline dipeptides were used to facilitate the synthesis of both CCL2 fragments. After assembly of the full-length peptide chain by NCL, a glutathione redox buffer was used to fold and oxidize the CCL2 protein. CCL2 was crystallized and the structure was determined by X-ray diffraction at 1.9-A resolution. This is probably one of the first crystal structures of a protein prepared using the sulfonamide safety-catch linker and NCL.
