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 ... 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.
