Source | An E.coli strain, that carries the cloned gene BamHI from Bacillus amyloliquefaciens H |
Assayed on | Lambda DNA |
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. |
Optimal SE-buffer | G (10 mM Tris-HCl (pH 7.6 at 25°C); 10 mM MgCl2; 50 mM NaCl; 1 mM DTT.) + BSA |
Enzyme activity (%) | B | G | O | W | Y | Rose | 25 - 50 | 100 | 75 - 100 | 75 - 100 | 25 - 50 | 100 |
|
Optimal temperature | 37oC |
Storage conditions | 10 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0,1 mM EDTA; 100 μg/ml BSA; 1 mM DTT; 50% glycerol. Store at -20°C. |
Ligation | After 50-fold overdigestion with enzyme approximately 90% of the DNA fragments can be ligated and recut. |
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.

Reagents Supplied with Enzyme |
10 X SE-buffer G, BSA
|
Methylation sensitivity | Not blocked by Dam methylation (GmATC) GGATCC |
Inactivation 20 minutes under | 65oC |
Notes | High enzyme concentration may result in star activity.
To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation.
