Reactivation of yeast glucose-6-phosphate dehydrogenase denaturated by saturated fatty acids.

P Tortora, N Burlini, G M Hanozet, A Guerritore.   

Abstract

Activity of yeast glucose-6-phosphate dehydrogenase, inactivated by treatment with saturated fatty acids, can be partially restored by incubation in a medium of suitable ionic composition. The effectiveness of ions in the reactivation process is inversely related to their 'chaotropic' properties. Time-dependence of reactivation extent suggests a 2-step mechanism of enzyme inactivation and the existence of an intermediate form that aggregates through a 2nd-order reaction, producing irreversibly inactive enzyme.
