| Assayed on | Adenovirus -2 DNA |
| Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of Adenovirus -2 DNA in 1 hour at 37°C in a total reaction volume of 50 μl. |
| Optimal SE-buffer | Y (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) |
| Enzyme activity (%) | | B | G | O | W | Y | R | | 75 - 100 | 50 - 75 | 0 - 10 | 0 - 10 | 100 | 50 |
