title: [Degradation of inactivated alpha-amylase by associated proteases].
abstract: Alpha-Amylase preparations often contain small quantities of proteolytic activity which are difficult to remove. On the example of fungal alpha-amylase, such associated proteases have been shown to possess a specific activity to the denatured amylase molecules. The amylase is not attacked under native conditions, whereas in the thermal denaturation a rapid degradation of only the inactivated molecules occurs. A specific metabolic function of these associated proteases in the return of denatured amylase molecules to the amino acid pool is suggested.
