Abstract

Horse‐liver alcohol dehydrogenase has been dissociated and denatured by 6 M gaunidinium hydrochloride. Removal of the denaturat under optimum conditions of the solvent leads to partial reactivation.The concentrations of the enzyme, as well as the coenzyme (NAD+ and Zn2+, affect the reactivation significantly, since high concentrations promote the formation of inactive aggregation products.Analyzing the kinetics of reactivation and reassociation, conditions far from equilibrium of dissociation‐association provide maximum yieldddd (∼ 70%). The sigmoidal kineic traces suggest a superposition of first‐order transconformation and‐second‐order association reactions; the latter are corrobosrated by the concentration dependence of thereactivation reaction.The coenzyme, NAD+, had no the kinetics of reactivation. Addition of Zn2+ leads to a significant decrease of the rate and yield of ractivation.The process of renaturation, as reflected by the regain of navive fluorescence show complex kinetics: rapid relaxations are followed by slower first‐order and secon‐order processes which parallel reactivtion.
