WebEnzyme inactivation is generally explained as a chemical process involving several phenomena like aggregation, dissociation into subunits, or denaturation (conformational changes), which occur simultaneously during the inactivation of a specific enzyme [2,3]. WebG-values of enzyme inactivations depended on the concentration of enzyme solutions. Previously added thiol compounds were found to protect the inactivation of sulfhydryl enzyanes by gamma irradiation. Radiolytic damages to enzymes and coenzymes were investigated quantitatively.

WebAllosteric enzymes change shape between active and inactive shapes as a result of the binding of substrates at the active site, and of regulatory molecules at other sites. In the simple case of an allosteric enzyme with an active and inactive form, the change in reaction rate with increasing substrate concentration is typically an "S-shaped" curve.
