Enzyme inhibitor This ester (FW = 251.28 g/mol; Abbreviation ATEE) is a substrate for chymotrypsin that is frequently used in assays of that enzyme. The reaction can be followed by observing the production of free carboxyl groups or by the decrease in absorbance at 237 nm and pH 7. Supersaturated stock solutions (i.e., 10-20 mM) can be prepared by dissolving ATEE in water at 85°C, followed by rapidly cooling to room temperature. These solutions are typically stable for six to twelve hours. N-Acetyl-L-tyrosine ethyl ester inhibits protein-disulfide reductase, glutathione-requiring; thiolsubtilisin; complement component C’.
