title: Glyoxalase II: molecular characteristics, kinetics and mechanism.
abstract: The mechanism that has been proposed for glyoxalase II [36] is summarized in Figure 3. It involves direct nucleophilic attack of an active-site histidine on the thiol ester substrate to form an acyl-imidazole intermediate which then rapidly hydrolyses. This is consistent with the known susceptibility of thiol esters to aminolysis and with the lability of acyl-imidazoles [47].
