Abstract

A search for neutral ester type specific substrates of a-chymotrypsin usable with enzyme concentrations of the order of 10-5. I1 has resulted in the selection of several acylated-L- valine methyl esters. The constants KS and k, have been evaluated for the a-chymotrypsin- catalyzed hydrolysis of acetyl-, chloroacetyl-and benzoyl-L-valine methyl ester in aqueous solutions at 25.0'and pH 7.90+ 0.01 and 0.1. lI in sodiuni chloride and for the latter specific ...
