The present disclosure pertains to the field peptide stapling and/or macrocyclization, where a structural motif is used to improve the properties of amino acid sequences (e.g. protease resistance, cellular penetration, biological activity). Also within the scope of the disclosure are methods for unstapling the S,S-tetrazine-containing amino acid sequence. The disclosure is also directed to methods for the reductive removal of thiocyanates from an amino acid sequence with cysteine to recycle back to the native amino acid sequence.
