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.; |
