Recognition Sequence :
Unit Definition :
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (dcm-) in 1 hour at 37°C in a total reaction volume of 50 μl.
Reaction Temperature :
Storage Buffer :
10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol
After 5-fold overdigestion with enzyme 95% of the DNA fragments can be ligated and recut.
Acinetobacter calcoaceticus B7
Assayed on :
Lambda DNA (dcm-)
Working buffer :
G (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 50 mM NaCl; 1 mM DTT.)
Non-specific hydrolisis :
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 37°C.
Concentration, u.a./ml :
20min Under 65°C
Methylation sensitivity :
Blocked by overlapping Dcm methylation (CmCWGG): CCANNNCCTGG or CCAGGNNNTGG.
