A traceless thioester-producing protocol featuring carboxypeptidase Y-mediated hydrazinolysis of cysteinyl prolyl leucine-tagged peptides has been developed. The hydrazinolysis followed by thioesterification affords cysteinyl prolyl thioesters. Self-editing of the tag and subsequent trans-thioesterification yields peptide thioesters. The developed protocol was successfully applied to the conversion of recombinant proteins to thioesters.
