Extended Data Fig. 4: Structural models of DNA-bound SpCas9 complexes.
From: R-loop formation and conformational activation mechanisms of Cas9

Cartoon representations of DNA-bound 6-, 8-, 10-, 12-, 14-, 16-, 18-nt match (checkpoint and catalytic) complexes of SpCas9. Each model was generated based on the corresponding map shown in Extended Data Fig. 3.
