Description
Recognition site and hydrolysis position:
CAGNNNCTG | CAGNNN↑CTG |
GTCNNNGAC | GTC↓NNNGAC |
Source: Pseudomonas stutzeri 217
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 |
25 | 50 | 10 | 25 | 100 | 100 |
Storage conditions: 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA, 50% glycerol; Store at -20°C.
Ligations:
After 5-fold overdigestion with enzyme > 95% of Lambda DNA fragments can be ligated with T4 DNA Ligase and recut.
Non-specific hydrolisis:
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C.
Reagents Supplied with Enzyme:
Methylation sensitivity: not tested
Notes: When using a buffer other than the optimal (suppied) SEBuffer, it may benecessary to add more enzyme to achieve complete digestion.
