Understanding the Core Mechanism: Native Chemical Ligation (NCL)
At its heart, the Native chemical ligation (NCL) protocol is an elegant solution to a long-standing challenge in molecular assembly. The process relies on the chemoselective reaction between two unprotected segments. Specifically, it involves reacting a C-terminal peptide thioester with an N-terminal cysteinyl peptide. This specific interaction is what facilitates the formation of a native-like peptide bond, allowing researchers to join segments that might otherwise be difficult to link.
From my observation, the beauty of this native peptide ligation strategy lies in its efficiency. Because it operates under relatively mild, aqueous conditions, it is increasingly used to generate proteins that are otherwise challenging to produce via traditional recombinant expression.
