Description

Recognition site and hydrolysis position:

VCTCGAGB VC↑TCGAGB
BGAGCTCV BGAGCT↓CV

Source: An E.coli strain that carries the cloned PspX I gene from Pseudomonas species A1-1
Unit definition:
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (HindIII-digest) in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on:
Lambda DNA (HindIII-digest)
Optimal SE-buffer: SE-buffer Y
Enzyme activity (%):

B G O W Y ROSE
50 50 25 75 100 25

Storage conditions: 10 mM Tris-HCl (pH 7.5); 200 mM KCl; 0.1 mM EDTA; 7 mM 2 -mercaptoethanol, 200 μg/ml BSA; 50% glycerol. Store at -20°C.
Ligations:
After 20-fold overdigestion with enzyme more than 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 10 u.a. of enzyme for 16 hours at 37°C.Reagents Supplied with Enzyme

10 X SE-buffer Y, BSA
Reagents Supplied with Enzyme:
Methylation sensitivity: not tested
Notes: To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml.
Do not use BSA for long incubation.
