|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||SE-buffer FaeI (33 mM Tris-acetate (pH 8.3 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.) + BSA|
|Enzyme activity (%)|
|25 - 50||50 - 75||10 - 25||10 - 25||75 - 100||100|
|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.|
|Ligation||After 3-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 2 u.a. of enzyme for 16 hours at 37°C.
|Reagents Supplied with Enzyme||
10 X SE-buffer FaeI, 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.
