The restriction endonuclease Bnal, being BamHl true isoshisomer, is isolated from B. natto B3364 strain. Its molecular weight, stability and optimal reaction conditions are studied. Comparative investigations have shown that according to these physicochemical characteristics the BamHl and Bnal enzymes differ from each other in spite of their analogous specificity.
