Methyltrypsin-catalyzed peptide synthesis has been studied by using conventional alkyl ester and p-guanidinophenyl ester derivatives of alpha-amino acid as the acyl donor component. They were found to be coupled with alpha-amino acid derivatives (acyl acceptor component) to produce dipeptide. The behavior of methyltrypsin toward both the substrates has been studied.

Although proteases are capable of synthesizing peptide bonds, they are not proficient at peptide fragment ligation. Further manipulations are needed to shift the native enzyme activity from the cleavage to the synthesis of peptides. This account reports on the synthetic potential of nonactivatable trypsinogen and zymogen-like enzymes designed to minimize proteolytic side reactions during peptide synthesis.
