Crystal structure of Cas9 in complex with guide RNA and target DNA
... In 2012, biochemical studies revealed that Cas9 is an RNA-guided DNA endonuclease with two nuclease domains (HNH and RuvC) [2] (Fig. 2(a)). The HNH domain cleaves the DNA strand complementary to the 20-nt guide sequence in the crRNAs (cDNA), while the RuvC domain cleaves the noncomplementary DNA str ...
