Aromatic L-amino acid decarboxylase (AADC) catalytic mechanism has been proposed to proceed through two consecutive intermediates (i.e., Michaelis complex and the external aldimine). Limited proteolysis of AADC that preferentially digested at the C-terminal side of Arg334 was slightly retarded in

Vibrio harveyi luciferase, an alpha beta dimer, was effectively inactivated by treatment with the methylation agent methyl p-nitrobenzene sulfonate. However, inactivation of luciferase in the presence of excess amounts of this reagent did not follow pseudo-first-order kinetics. After taking the

When Trimeresurus flavoviridis phospholipase A2 was reacted with methyl p-nitrobenzenesulfonate, its activity decreased following first-order kinetics. The pH dependence of the rate constants of inactivation showed that His-48 with an apparent pKa of 6.5 controls the reaction. In the pH

Incubation of L-threonine dehydrogenase from Escherichia coli with methyl p-nitrobenzenesulfonate results in a time- and concentration-dependent loss of enzymatic activity. As the concentration of the methylating agent is increased, the rate of inactivation reaches a limiting value of 0.01 min-1
