This protein adopts a bilobed architecture consisting of a REC lobe and a NUC lobe connected by an arginine-rich bridge helix and a linker loop. The C-terminal region, known as the PI domain, can be divided into a Topoisomerase-homology (TOPO) domain (Pfam:PF18070) and a C- terminal domain (this entry). This domain forms a twisted six- stranded anti-parallel beta-sheet [1,2].

Cas9 cleaves double-stranded DNA targets with a protospacer adjacent motif (PAM) and complementarity to the guide RNA. The Cas9 WED domain has a fold comprising a twisted five-stranded beta sheet flanked by four alpha helices, and is responsible for the recognition of the distorted repeat: anti-repeat duplex. WED domains are responsible for the recognition of single-guide RNA scaffolds [1].

This domain, and the HNH (Pfam:PF13395) domain of Cas9, are used to cleave the DNA strands complementar ...This entry represent a RuvC endonuclease domain (RNAseH-like) domain found in CRISPR-Cas9 from Streptococcus pyogenes and related sequences [1-5]. This domain, and the HNH (Pfam:PF13395) domain of Cas9, are used to cleave the DNA strands complementary (target) and non-complementary (non-target) to the crRNA, respectively [5]. This domain is related to Pfam:PF18541.

Cas9 cleaves double-stranded DNA targets with a protospacer adjacent motif (PAM) and complementarity to the guide RNA. When this domain is combined with the C-terminal domain it is called the Pam-interacting (PI) domain. The Cas9 orthologs from different microbes have highly divergent sequences but their PI domains share a conserved core fold and recognize distinct PAM sequences [1].
