| Source | Flavobacterium aquatile N3 |
| Assayed on | pUC19 DNA |
| Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of pUC19 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.) + BSA |
| Enzyme activity (%) | | B | G | O | W | Y | R | | 25 - 50 | 50 - 75 | 10 - 25 | 10 - 25 | 100 | 100 |
|
| Optimal temperature | 37oC |
| Storage conditions | 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C. |
| Ligations | After 2-fold overdigestion with enzyme more then 90% of the DNA fragments can be ligated with T4 DNA Ligase at 16°C and recut. |
| Non-specific hydrolisis | No nonspecific activity was detected after incubation of 1 μg of pUC19 DNA with 1 u.a. of enzyme for 16 hours at 37°C.

| Reagents Supplied with Enzyme |
10 X SE-buffer Y, BSA |
| Methylation sensitivity | Blocked by CmATG methylation |
| Inactivation 20 minutes under | 65oC |
| Notes | To obtain 100% activity, BSA should be added the 1x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation. |
