As one tour-de-force, Gasiunas... WebJan 1, 2024 · The many known Cas9 orthologs identified from Streptococci share a conserved RxR PAM-binding motif within the PI domain that confers a unanimous NGG PAM specificity. To reveal the PAM diversity among Streptococci Cas9s, SpCas9 was used as a query to mine SpCas9-like proteins via BLASTp in the NCBI database.
