Source: An. E.coli strain that carries the cloned Alu I gene from Arthrobacter luteus
Unit definition:
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer Y
Enzyme activity (%):
B | G | O | W | Y | ROSE |
75 | 75 | 10 | 50 | 100 | 50 |
