Streptococcus pyogenes Cas9 is a type II-A Cas9 protein and is the most used in most current CRISPR-based genetic engineering methodologies (1). CRIPSR RNAs (crRNAs) fused to trans-activating CRISPR RNAs (tracrRNA) direct sequence-specific cleavage by Cas9, introducing double-stranded breaks in cell-invading DNA in bacterial and archaeal CRIPSR/Cas9 systems (1,2). Cas9 requires the 5’-NGG-3’ protospacer adjacent motif (PAM) to destabilize the target DNA (3). Cas9’s HNH endonuclease domain cleaves the strand complementary to the crRNA while its RuvC endonuclease domain cleaves the non-complementary strand (2).
