Two types of artificial tools that cut double-stranded DNA through hydrolysis of target phosphodiester linkages have been recently developed. One is the chemistry-based artificial restriction DNA cutter (ARCUT) that is composed of a Ce-IV-EDTA complex, which catalyses DNA hydrolysis, and a pair of pseudo-complementary peptide nucleic acid fragments for sequence recognition. Another type of DNA cutter, zinc finger nuclease (ZFN), is composed of the nuclease domain of naturally occurring Fokl restriction endonuclease and a designed zinc finger DNA-binding domain. For both of these artificial tools, the scission site and specificity can be freely chosen according to our needs, so that even huge genomic DNA sequences can be selectively cut at the target site. In this article, the chemical structures, preparation, properties, and typical applications of these two man-made tools are described.
