Summary:An object of the present invention is to provide a novel method having high efficiency and versatility for a peptide thioester and peptide. The present invention provides a method for producing a peptide thioester, comprising the steps of: (1) providing a peptide thioester having a CGC triplet at the C-terminal; (2) causing a transfer between an SH group of the C-terminal cysteine and a carbonyl group of the glycine in the CGC triplet to obtain an R-X-CG-thioester; and (3) causing, in the R-X-CG-thioester, a transfer between the SH group of the cysteine and a carbonyl group of X, and a transfer between an amino group of the cysteine and a thiol group of the glycine to obtain a peptide thioester, and a method for producing a peptide using the peptide thioester produced by this method.
