[Isolation and properties of site-specific endonuclease BspTS514I from the thermophilic bacteria Bacillus species TS514].
New site-specific endonucleases BspBS31I, BstBS32I, BspIS41, BstTS5I, BspTS514I were isolated from five thermophilic soil bacteria Bacillus sp. BS31, B. stearothermophilus BS32, Bacillus sp. IS4, B. stearothermophilus TS5, Bacillus sp. TS514. The enzymes are isoschizomers of the restriction endonuclease BbvII. Endonuclease BspTS514I was obtained pure from interfering contaminations by two consecutive chromatographies on blue agarose and hydroxyapatite. The enzyme exhibits a maximal activity at 55 degrees C in 10 mM tris-HCl (pH 9.2), 10 mM MgCl2 and 50 mM NaCl.
