Activity Regulation
Binding Site
Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units.; EC=3.2.1.1;
DNA Binding
EC Number 3.2.1.1
Enzyme Function FUNCTION: This amylase is a highly liquefying-type: oligomers appeared at the beginning of incubation, followed by a graded decrease in the amounts of maltotriose, maltose and glucose in prolonged incubation.
Temperature Dependency BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is about 90 degrees Celsius. Highly thermostable. Retains 70% of its maximal activity after heating 1 hour at 90 degrees Celsius, but no decrease in activity was observed within the same time at 80 degrees Celsius.;
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 5.5. Stable above pH 5.5.;
Pathway
