[BME 361 I--a new site-specific deoxyribonuclease type II from Bacillus megaterium 361]

Bme 361 I, a new site-specific type II deoxyribonuclease, was purified from Bacillus megaterium 361 by chromatography on phosphocellulose P 11 and hydroxylapatite. The enzyme recognizes and cleaves the nucleotide sequence 5'-GG decreases CC-3' in double-strand DNA. Thus it is a true isoschizomer of deoxyribonucleases Hae III and BspR I.
