Cas9 Orthologs with Minimal PAM Requirements

In their recent paper Chatterjee and colleagues (2018) describe a natural protospacer adjacent motif (PAM) plasticity of previously uncharacterized Cas9 endonuclease from Streptococcus canis (ScCas9).  Chatterjee et al (2018) report ScCas9’s affinity to minimal 5’-NNG-3’ PAM sequences and describe its accurate editing capabilities, […]
