| Source | E.coli strain that carries the cloned Sal I gene from Streptomyces albus |
| Assayed on | Lambda DNA (HindIII-digest) |
| Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (HindIII-digest) in 1 hour at 37°C in a total reaction volume of 50 μl. |
| Optimal SE-buffer | O (50 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 100 mM NaCl; 1 mM DTT.) |
| Enzyme activity (%) | | B | G | O | W | Y | Rose | | 0 - 10 | 10 - 25 | 100 | 25 - 50 | 0 - 10 | 5 |
