WebMost recently, it was reported that three new SpCas9 variants, SpCas9-NRRH, SpCas9-NRTH, and SpCas9-NRCH, could recognize non-G PAMs (NRNH, where R is A or G and H is A, C, or T) in human cells (Miller et al., 2024). WebSpCas9 is driven by the sum of two forces: the positive charge of the chromosome-binding motif of the protein, and the RNA:DNA interaction between the guide RNA and the target DNA. Therefore, weakening the binding efficiency of SpCas9 will increase the criteria for a more precise match between the guide RNA and the target DNA for unwinding of the
