| Source | An E.coli strain, that carries the cloned gene CciNI from Curtobacterium citreus N |
| Assayed on | pUC-AD plasmid DNA.
pUC-AD (22562 bp) was obtained by a ligation of the vector pUC19/XbaI and a XbaI-fragment of Adenovirus-2 DNA, 19876 bp in length. pUC-AD contains 6 recognition sites of CciNI. |
| Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of pUC-AD 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 | Rose | | 25 - 50 | 50 - 75 | 75 - 100 | 75 - 100 | 100 | 100 |
|
| Optimal temperature | 37oC |
| 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. |
| Ligation | After 10-fold overdigestion with enzyme about 95% of the DNA fragments can be ligated and recut. |
| Non-specific hydrolisis | No nonspecific activity was detected after incubation of 1 μg of DNA pUC-AD with 10 u.a. of enzyme for 16 hours at 37°C.
