Summary Two series of inverse substrates,m-guanidinophenyl andm-(guanidinomethyl)phenyl esters derived fromN-(tert-butyloxycarbonyl)amino acid, were prepared as an acyl donor component for trypsin-catalyzed peptide synthesis. The kinetic behavior of these esters toward tryptic hydrolysis was analyzed. They were found to couple with an acyl acceptor such asl-alaninep-nitroanilide to produce dipeptide in the presence of trypsin.Streptomyces griseus trypsin was a more efficient catalyst than the bovine trypsin. Within the enzymatic peptide coupling methods, this approach was shown to be advantageous, since the resulting peptides are resistant to the enzymatic hydrolysis.
