Crystal structure of cas9
WebThe crystal structure of the latter RNA contains two independent duplexes per asymmetric unit, thus allowing observation of four independent UaU dimer steps. ... The development of CRISPR-Cas9 ... Cas9 features a bi-lobed architecture with the guide RNA nestled between the alpha-helical lobe (blue) and the nuclease lobe (cyan, orange, and gray). These two lobes are connected through a single bridge helix. There are two nuclease domains located in the multi-domain nuclease lobe, the RuvC (gray) which cleaves the non-target DNA strand, and the HNH nuclease domain (cyan) tha…

WebHowever, in the crystal structure of Cas9 bound to such a partial duplex, the HNH active site is not positioned close to the scissile phosphate (Figure 5c). One possible reason for this inactive conformation could be due to the lack of a 3′ end of sgRNA used for crystallization, which is critical for stabilizing the closed active state of ...
