IUPAC definition : Endonucleases which recognize specific base sequences within a DNA helix, creating
a double-strand break of DNA. Type I restriction enzymes bind to these recognition
sites but subsequently cut the DNA at different sites. Type II restriction enzymes
both bind and cut within their recognition or target sites.;
