Activation of fungal alpha-amylase by dithioerythritol
Acta Biologica Et Medica Germanica
|January 1, 1979
Abstract:
The activity of fungal alpha-amylase has been shown to be influenced by disulfide-reducing reagents. Thus, the enzymatic activity increases in the presence of dithioerythritol or 2-mercaptoethanol. L-Cysteine is also capable of increasing the activity, but the activation competes with an inactivation reaction which dominates at higher reagent concentrations (greater than 20 mM). A possible scheme interpreting the results is given.
