Cutting sequence: (A/G)↓CCGG(T/C)

Isoschizomere: Cfr10 I, BsrF I

 

Source: Bacillus species.

 

Buffer supplied:  10x BssA I.

 

Substrate for unit definition: λ DNA.

 

Reaction conditions:  100 mM KCl, 20 mM Tris-HCl  (pH 8.5 at 25°C), 3  mM MgCl2, 0.04% Triton X-100, 100 μg/ml BSA. Incubate at 65°C under parafin oil.

 

Storage buffer: 50 mM KCl, 10 mM Tris-HCl  (pH 7.4),  0.1 mM EDTA,  1 mM dithiothreitol, 200 μg/ml BSA and 50% glycerol. Store at -20°C.

 

Absence of contaminants: Fifty units of BssAI do not produce any unspecific  cleavage products after 16 hrs incubation with 1 μg of  λ DNA at 65°C.  After 30-fold overdigestion with BssAI, greater than 95% of the DNA fragments can be ligated and recut with this enzyme.

 

Star activity:  Low salt concentration or large excess of enzyme results in the appearance of star activity.

 

Heat inactivation: No.
