Trypsin-catalyzed peptide synthesis has been studied by using ''inverse substrate,'' i.e., p-amidinophenyl ester derived from alpha-amino acid derivative as an acyl donor component. Inverse substrate can afford acyl trypsin in a very specific manner, liberating the site-specific p-amidinophenyl moiety as the leaving group. Thus a variety of alpha-amino acid residues which are a part of p-amidinophenyl ester can be involved in the trypsin-catalyzed coupling reaction. The method has been shown to be successful as expected. In conclusion, the method was proposed as a new procedure which overcomes the disadvantage of enzymatic peptide synthesis.
