Description
Recognition site and hydrolysis position:
ACGT | A↑CGT |
TGCA | TGC↓A |
Source: An E.coli strain, that carries the cloned HpySE 526I gene from Helicobacter pylori SE526.
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.
Assayed on:
pUC19 DNA
Optimal SE-buffer: SE-buffer Y
Enzyme activity (%):
B | G | O | W | Y | ROSE |
75 | 75 | 10 | 25 | 100 | 50 |
Storage conditions: 10 mM Tris-HCl (pH 7.6); 100 mM NaCl; 0,1 mM EDTA; 200 μg/ml BSA; 1 mM DTT; and 50% glycerol. Store at -20°C.
Ligations:
After 5-fold overdigestion with enzyme about 95% of the DNA fragments can be ligated with T4 DNA Ligase and recut.
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.
Reagents Supplied with Enzyme:
Methylation sensitivity: Blocked by CG methylation
