Synthetic S. pyogenes Cas9s with novel PAM recognition
In 2015, Keith Joung’s lab performed...2015). From these screens, they identified four novel SpCas9 variants with altered PAM binding specificity...remaining variants (VQR, EQR, and VRER) recognize novel PAM sequences (shown above). The VQR, EQR, and VRER...
