WebApr 29, 1997 · An RNA-cleaving DNA enzyme, in contrast, is responsible for both target recognition and cleavage and operates with catalytic turnover. The 10-23 enzyme has a catalytic rate of ≈0.1 min −1 and Km < 1 nM under simulated physiological conditions. WebDNA cleavage domain The non-specific DNA cleavage domain from the end of the FokI endonuclease can be used to construct hybrid nucleases that are active in many different cell types. The FokI domain functions as a dimer, requiring two constructs with unique DNA binding domains for sites in the target genome with proper orientation and spacing.
WebApr 14, 2024 · CRISPR-Cas immune systems provide immunity against viruses using RNA-guided endonucleases like Cas9 and Cas12a. Viruses can evade these Cas endonucleases through the evolution of mutants that block cleavage by creating mismatches between the guiding RNA and the viral DNA. We show that although Cas12a can tolerate some …
