Recognition site | C↑CCGGG GGGCC↓C |
Source | An E.coli strain, that carries the cloned gene XmaI from Xanthomonas malvacearum |
Assayed on | Adenovirus -2 DNA |
Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of Adenovirus -2 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 | 75 - 100 | 50 - 75 | 0 - 10 | 0 - 10 | 100 | 50 |
|
Optimal temperature | 37oC |
Storage conditions | 20 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C. |
Ligation | After 3-fold overdigestion with enzyme 95% of the DNA fragments can be ligated. Of these 90% can be recut. |
Non-specific hydrolisis | No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 3 u.a. of enzyme for 16 hours at 37°C
