title: [Site-specific endonuclease BspR7I from thermophilic strain of Bacillus sp. R7].
abstract: A site-specific endonuclease which recognizes the sequence 5'-CCTNAGG-3' was purified to homogeneity from the thermophilic strain Bacillus sp. R7. The endonuclease (BspR7I) is monomeric protein with an apparent molecular weight of 37 kD. The enzyme is active over a wide range of NaCl concentrations, pH, and temperatures. BspR7I cleaves DNA substrates according to the scheme: 5'-CC decreases TNAGG-3' 3'-GGANT increases CC-5', hence the endonuclease represents an isoschizomer of Bsu361.
