| banai a new isoschizomer of the type ii restriction endonuclease haeiii discovered in a bacillus anthracis isolate from amazon basin. | bacillus anthracis was isolated and identified from a bacterial collection of samples from the amazon river bank. type ii restriction endonuclease activity was detected in this prokaryote, the enzyme was purified, the molecular mass of the native protein estimated by gel filtration, and optima ph, temperature and salt requirements were determined. quality control assays showed complete absence of 'non-specific nucleases'. restriction cleavage analysis and dna sequencing of restriction fragments ... | 2002 | 12393207 |
