This is an alpha-helical lobe domain found in Cas9 proteins. Cas9 enzymes adopt a bilobed architecture composed of a nuclease lobe containing juxtaposed RuvC and HNH nuclease domains and a variable alpha-helical lobe likely to be involved in nucleic acid binding. Amino acid residues located in both the nuclease and alpha-helical lobe clefts are highly conserved within type II-A Cas9 proteins [1].	Domain
A	PF22702	Cas9 RuvC domain (Cas9_RuvC)	Cas9 RuvC domain	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 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.	Domain
