A site-specific endonuclease SscL1 I preparation has been isolated and purified to near homogeneity from the strain Staphylococcus sp. L1 without admixtures of other nuclease activity. DNA cleavage proceeds according to the scheme: 5'-G down arrow ANTC-3' 3'-CTNA up arrow G-5', and thus the isolated enzyme is an isoschizomer of restriction endonuclease HinfI and belongs to the second class of restriction endonucleases. SscL1 I works over a broad range of temperature and pH. The enzyme is characterized by high stability during storage.
