Convergent Synthesis
Convergent Synthesis — A peptide synthesis strategy where multiple fragments are synthesized separately and then joined, enabling production of longer peptide chains with higher purity.
What Is Convergent Synthesis?
Convergent synthesis is a strategy for making long peptides by independently synthesizing shorter fragments, then joining them. This approach circumvents the exponential decrease in yield and purity that occurs with stepwise SPPS of long sequences. Each fragment is purified to high purity before ligation.
Strategies
- NCL: Thioester + Cys fragments joined in aqueous solution to give native peptide bond
- Segment condensation: Protected fragments coupled in solution using coupling reagents
- Enzymatic: Sortase-mediated ligation of LPXTG + GGG fragments
