Effect of Copper Salts on Peptide Bond Formation Using Peptide Thioesters

(Matrix presented) In the present paper, systematic studies revealed that Cu(I) salts in general and Cu(II) salts under certain circumstances promote effective reaction between peptide thiol esters and the N-terminal amino function of a second peptide seg
