[Effect of N-alkylimidazoles on oxidation of o-dianizidine catalyzed by horseradish peroxidase].
Effect of a number of N-alkylimidazoles (from N-methyl to N-octylimidazole) on peroxidase oxidation of o-dianizidine at pH 8.0 is studied. Alkylimidazoles studied are found to activate the reaction under given conditions, the activation type being non-competitive KA and (alpha) values are similar for all the activators, which suggests a similar mechanism of their action. Similar KA values suppose an insignificant role of hydrophobic interactions in the binding of N-alkylimidazoles with the enzyme.
