Artificial Restriction DNA Cutter Using Nuclease S1 for Site‐Selective Scission of Genomic DNA

By combining a pair of pseudo‐complementary peptide nucleic acids (pcPNAs) with S1 nuclease, a novel tool to cut DNA at a predetermined site can be obtained. Complementary pcPNAs invade the DNA duplex and base pair to each strand of a target site, creating single‐stranded regions that are cleaved by S1 nuclease. The scission site can be freely modulated by the design of pcPNAs. This method can be used to cleave a single site in the human genome....
