Acylation of α-Chymotrypsin by Oxygen and Sulfur Esters of Specific Substrates: Kinetic Evidence for a Tetrahedral Intermediate

The acylation step of the α-chymotrypsincatalyzed hydrolysis of N-acetyl-L (or DL)-tryptophan p-nitrophenyl, p-nitrothiophenyl, ethyl, and thiolethyl esters has been studied by the stopped-flow technique at 25°. The acylation rate constant, k(2), and the enzyme substrate dissociation constant, K(s),...
