Definition: A restriction enzyme is a DNA-cutting protein, found mainly in bacteria and archaea, that recognizes a specific short DNA sequence and cleaves the double helix at or near that site. By ...
Sau3AI is a type II restriction enzyme widely used for genetic manipulation, such as genome library construction. Sau3AI consists of two domains, the N-terminal domain (Sau3AI-N) and the C-terminal ...
Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...
