A catalytically essential histidine residue (His-195) of chloramphenicol acetyltransferase (CAT) acts as a general base in catalysis, abstracting a proton from the primary hydroxy group of chloramphenicol. The pKa of His-195 has been determined from the pH-dependence of chemical modification.

Protein science : a publication of the Protein Society, 7(8), 1802-1810 (1999-03-19)
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

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

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

The binding of the apolar fluorescent dye 8-anilinonaphthalene-1-sulfonate (ANS) to Naja naja atra phospholipase A2 (PLA2) as well as the enhancement of ANS fluorescence of the PLA2-ANS complex decreased with increasing pH in a pH range from 3 to 9.
