…-Lx1-Ly1-…-Lym-NH2 with phenylalanine or tyrosine in Lx1 and glycine or alanine in the other positions were synthesized using elastase and δ-chymotrypsin to catalyse the formation of the peptide bonds adjacent to the aromatic residue. Such oligopeptides are useful substrates for studying the secondary specificity of chymotrypsin-like proteases.

δ-Chymotraypsin catalyzes peptide-bondformation between acylated amino-acid and peptide esters as the carboxyl component and amino-acid and peptide amides as the amino component. The conditions under which enzyme-catalyzed coupling can be used for fragment condensation in peptide synthesis is investigated. To illustrate the method the synthesis of tetra-, penta- and hexapeptides of the structure Ac-Lxn
