SOME DIFFERENCES BETWEEN BAMHI AND BNAI, THE RESTRICTASES WITH THE SAME SPECIFICITY

Summary

    The restriction endonuclease Bnal, being BamHl true isoshisomer, is isolated from Bac. 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.
