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.
Usage
Sensitive to impurities present in some DNA preparations. For example, DNA purified by standard miniprep procedures is cleaved at lowe rates. To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
Properties
Campatible Ends NdeI
Thermal inactivation enzyme is inactivated by incubation at 65°C for 20 mins.
Methlation effect Methylation sensitivity not tested
Non-specific hydrolisis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 20 u.a. of enzyme for 16 hours at 37°C.
Ligations After 10-fold overdigestion with enzyme 80% of the DNA fragments can be ligated and recut. In the presence of 10% PEG ligation is better.
Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 1mM DTT; 200 μg/ml BSA, 50% glycerol; Store at -20°C.
Optimal temperature 37°C
Optimal buffer Y?(33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) +?BSA
Assayed on Lambda DNA
Source E.coli strain that carries the cloned FauND I gene from Flavobacterium aquatili ND
Recognition sites CA↑TATG
