Native chemical ligation is utilized for the generation of homogenous samples of full-length proteins with site-specific chemical modifications. It is commonly used for the site-specific installation of post-translational modifications, in particular those that to-date cannot be readily incorporated by other means. Here, we describe the assembly of recombinantly expressed and/or chemically synthesized protein fragments via this chemoselective bioconjugation reaction. Derivative ligation methods are also discussed to enable the greatest amount of flexibility for the generation of a desired protein.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
