The interaction of α-chymotrypsin with α-N-acetyl-l-phenylalaninamidoxime - Peterson, P.E.; Niemann, C. (Elsevier)
α-N-acetyl-l-phenylalaninamidoxime, i.e., l-α-acetamido-β-phenylpropionamidoxine, although capable of combining with the catalytically active site of α-chymotrypsin is not hydrolyzed by this enzyme under conditions where the corresponding amide and hydroxamide will function as substrates.
