WebReaction. In native chemical ligation, the ionized thiol group of an N-terminal cysteine residue of an unprotected peptide attacks the C-terminal thioester of a second unprotected peptide, in an aqueous buffer at pH 7.0 and room temperature. This transthioesterification step is reversible in the presence of an aryl thiol catalyst, rendering the reaction both … WebMar 5, 2003 · We conclude that the enhanced reactivity of MCRred1 is due to the replacement of a relatively exchange-inert thiol ligand in MCRox1 with a weakly coordinating upper axial ligand in red1 that can be easily replaced by incoming ligands.
