Investigations of biological processes by using peptide, protein, or its derivative are undoubtedly valuable. In this field, chemical synthesis of native or modified peptides/proteins is indispensable. Fragment condensation strategy, such as thioester method or native chemical ligation, is widely used for chemical synthesis of large peptides and proteins. C-Terminal peptide/protein thioesters have been used as building blocks for the fragment condensation strategy. Therefore, development of methodologies for preparing C-terminal peptide/protein thioesters is one of the most attracting theme in recent peptide/protein chemistry field. In this review, the methodologies for preparing C-terminal peptide/protein thioesters utilizing chemistry, biochemistry, or gene engineering are summarized.
