Source: Lysinibacillus manganicus An22


500 – 1000 u/ml         Store at -20°C

Recognition Sequence:



Sourse: Lysinibacillus manganicus An22

Supplied in: 10 mM Tris-HCl (pH 7.4); 50 mM NaCl; 0,1 mM EDTA; 200 µg/ml BSA; 1 mM  DTT; 50% glycerol.

Reaction Conditions:

 1XSEBuffer B.
Incubate at 37°C.

1XSEBuffer B: 10 mM Tris-HCl (pH 7.6 @ 25ºC), 10 mM MgCl2, 1 mM DTT

Unit Definition: One unit is defined as the amount of enzyme required to digest 1 µg of  λ DNA in 1 hour at 37°C in a total reaction volume of 50 µl.

Quality Control Assays

Ligation: After 10-fold overdigestion with ZraI, approximately  90% of λ DNA fragments can be ligated with T4 DNA Ligase and recut. In the presence of 10% PEG ligation is better.

16-Hour Incubation: A 50 µl reaction containing 1 µg of λ DNA and 10 units of enzyme incubated for 16 hours resulted in the same pattern of DNA bandsas a reaction incubated for 1 hour.

Oligonucleotide Assay: No detectable degradation of a single- and double-stranded oligonucleotide was observed after incubation with 10 units of enzyme for 3 hours.

Enzyme properties

Activity in SEBuffers:

SEBuffer B              100%

SEBuffer G         50- 75%

SEBuffer O         25- 50%

SEBuffer W         25- 50%

SEBuffer Y          75-100%

SEBuffer ROSE        100%

When using a buffer other than the optimal (suppied) SEBuffer, it may be necessary to add more enzyme to achieve complete digestion.

Heat Inactivation: Yes   (80°C for 20 minutes)

Reagents supplied with enzyme: 10XSEBuffer B

Notes: High enzyme concentration may result in star activity. The minimum number of units that resulted in complete digestion of 1 µg of substrate DNA in 16 hours is 0,5. Zra I cleaves linear plasmid DNA at a rate 1,5-2 times higher than supercoiled plasmid DNA.
