PalA I

Description

Recognition site and hydrolysis position:

Source: An E. coli strain , that carries the cloned gene from Pseudomanas alcaligenes BS17Unit 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.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer Y
Enzyme activity (%):

Storage conditions: 10 mM Tris-HCl (pH 7.5); 100 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol; Store at -20°C.
Ligations:
After 5-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and 95% of these can be recut.
Non-specific hydrolisis:
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C. Reagents Supplied with Enzyme 10 X SE-buffer Y
Reagents Supplied with Enzyme:
Methylation sensitivity: Blocked by CG methylation.
