Abstract: The characterization of the S' subsite specificity of native and ethylated alpha-chymotrypsin has been studied via acyl transfer reaction in acetonitrile containing 10 vol% of water. Using Ac-Tyr-OEt as acyl donor, we investigated the partitioning of acyl-chymotrypsins between water and amino acid and peptide-derived nucleophiles. For the investigation of S'2 subsite specificity, a series of 19 dipeptides of the general structure Ala-Xaa (Xaa represents all natural amino acids except cysteine) were used. From …
