Figure 6: SpdCas9-assisted gene editing by the type II-C Cas9 from Neisseria cinerea (NcCas9).

(a) NcCas9 and SpdCas9 targets in the human POR locus. Targets are indicated by bars and PAMs are highlighted in purple (SpdCas9) and dark blue (NcCas9). (b) NcCas9 target cleavage activities (% indels) with or without the assistance of SpdCas9 binding at proximal locations. The sgRNA numbers correspond to the target numbers in a. M, wide-range DNA markers; ND, not determined.
