    • Rapid Additive-Free Selenocystine–Selenoester Peptide Ligation 

      Mitchell, Nicholas J.; Malins, Lara R.; Liu, Xuyu; Thompson, Robert E.; Chan, Bun; Radom, Leo; Payne, Richard J.
      Published 2015-10-21
      We describe an unprecedented reaction between peptide selenoesters and peptide dimers bearing N-terminal selenocystine that proceeds in aqueous buffer to afford native amide bonds without the use of additives. The ...
