title: [A new type of cleavage of the recognition site by the site-specific endonuclease Bst 4.4I from Bacillus stearothermophilus 4.4].
abstract: A site-specific endonuclease Bst 4.4I was isolated from the cell extract of Bacillus stearothermophilus 4.4 and partially purified by chromatography on Ultragel AcA-44 and heparin-Sepharose. It was shown that the endonuclease cleaves lambda and M13 DNA yielding distinct fragments just as endonucleases of II and III types but, in contrast to them can produce two two-strand cuts separated with 30 to 32 nucleotides in the region of the recognition site.
