Abstract
A new restriction endonuclease Sst12I belonging to the II type and recognizing the sequence 5'-CTGCAG-3' was isolated from the bacterial strain Streptomyces sp. St-12. The enzyme hydrolyzes DNA between adenine and guanine residues; thus, it is a true isoschizomer of restrictase PstI. In contrast to PstI, the restriction endonuclease Sst12I hydrolyses DNA both at 37 degrees and 55 degrees C and remains active after long-term storage.
