Abstract

The CRISPR-associated endonuclease Cas9 can be targeted to specific genomic loci by single guide RNAs (sgRNAs). Here, we report the crystal structure of Streptococcus pyogenes Cas9 in complex with sgRNA and its target DNA at 2.5 Å resolution. The structure revealed a bilobed architecture composed of target recognition and nuclease lobes, accommodating the sgRNA:DNA heteroduplex in a positively charged groove at their interface. Whereas the recognition lobe is essential for binding sgRNA and DNA, the nuclease lobe contains the HNH and RuvC nuclease domains, which are properly positioned for cleavage of the complementary and noncomplementary strands of the target DNA, respectively. The nuclease lobe also contains a carboxyl-terminal domain responsible for the interaction with the protospacer adjacent motif (PAM). This high-resolution structure and accompanying functional analyses have revealed the molecular mechanism of RNA-guided DNA targeting by Cas9, thus paving the way for the rational design of new, versatile genome-editing technologies.

  • SpCas9-NG shows reduced editing efficiency on 5′-NGC-3′ PAM targets and tends to increase off-target activity.

    “For example, SpCas9-NG shows reduced editing efficiency on 5′-NGC-3′ PAM targets and tends to increase off-target activity (Nishimasu et al., 2014).”

    From Emerging applications of gene editing technologies for the development of climate-resilient crops (2025) · cites this paper as Nishimasu et al., 2014

    The Results section on PAM specificity examines SpCas9 and PI-domain chimeras at NGG and NGGNG PAMs, not SpCas9-NG at NGC targets. A search of our copy for SpCas9-NG, NGC editing efficiency, and off-target activity found no passage assessing the claimed effects. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
