Figure Lengend Snippet: (A) Unrooted phylogenetic tree of meningococcal Cas9 orthologs. Groups 1 (blue), 2 (orange), and 3 (green) have PIDs with >98%, ~52%, and ~86% identity to Nme1Cas9, respectively. Three representative Cas9 orthologs (one from each group) (Nme1Cas9, Nme2Cas9 and Nme3Cas9) are indicated.

Figure Lengend Snippet: (A) Nme2Cas9 genome editing of endogenous human sites in HEK293T cells following transient transfection of Nme2Cas9- and sgRNA-expressing plasmids. 40 sites were screened initially (Table S1); the 14 sites shown (selected to include representatives of varying editing efficiencies, as measured by TIDE) were then re-analyzed in triplicate. An Nme1Cas9 target site (with an N4GATT PAM) was used as a negative control.

Figure Lengend Snippet: (A) In vitro cleavage assay of Nme1Cas9 and Nme2Cas9 in the presence of five previously characterized anti-CRISPR proteins (10:1 ratio of Acr:Cas9). Top: Nme1Cas9 efficiently cleaves its target in the absence of an Acr or in the presence of a negative control Acr (AcrE2). All five type II-C Acr families inhibited Nme1Cas9, as expected. Bottom: Nme2Cas9 inhibition mirrors that of Nme1Cas9, except for the lack of inhibition by AcrIIC5Smu.

Figure Lengend Snippet: (A) Nme2Cas9 and SpyCas9 efficiencies vary based on the locus and target site. Dual sites (flanked by NGGNCC sequences) throughout the genome were selected for direct comparisons of editing by the two orthologs in HEK293T cells. Box-and-whisker plots indicate editing efficiencies at 28 dual sites by Nme2Cas9 and SpyCas9 (left). The sites that showed no editing were excluded from the analysis. Relative efficiencies of Nme2Cas9 and SpyCas9 show that Nme2Cas9 is less efficient than SpyCas9 (right), on average. Editing efficiencies by both Cas9 orthologs at all 28 sites were included in the analysis of relative efficiencies in the right panel.
