Zra I

Enzyme name Zra I
Prototype (AatII)
SKU SE-E463
Turbo version Not available
High-concentration version Not available
Recognition site
5'… GAC▼GTC …3'
3'… CTG▲CAG …5'
Source An E.coli strain that carries the cloned Zra I gene from Zoogloea ramigera 11
Optimal buffer SE-buffer B
Optimal temperature 37 °C
Inactivation temperature 80 °C
Buffer activity
BGOWYROSE
10050252575100
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.
Assayed on Lambda DNA
Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
Ligation After 10-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut. In the presence of 10% PEG
Nonspecific hydrolysis 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.
Methylation sensitivity not tested
Supplied with enzyme 10 X SE-buffer B
Notes High enzyme concentration may result in star activity.The minimum number of units that resulted in complete digestion of 1 ug of substrate DNA in 16 hours is 0,5.ZraI cleaves linear plasmid DNA at a rate 1,5-2 times higher than supercoiled plasmid DNA.
