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	PF17893	CRISPR-associated endonuclease Cas9 beta-hairpin domain (Cas9_b_hairpin)	CRISPR-associated endonuclease Cas9 beta-hairpin domain	This is beta-hairpin domain found in Cas9 proteins from Actinobacteria. The beta-hairpin domain is not conserved in all type II-C Cas9 proteins. The beta-hairpin in Cas 9 from Streptococcus pyogenes blocks the HNH domain active site [1].	Domain
A	PF17894	Topo homolgy domain in CRISPR-associated endonuclease Cas9 (Cas9_Topo)	Topo homolgy domain in CRISPR-associated endonuclease Cas9	This is the Topo-homology domain found in Cas9 proteins from Actinobacteria. This domain bears structural similarity to a domain found in topoisomerase II [1].	Domain
A	PF18525	Cas9 C-terminal domain (Cas9_C)	Cas9 C-terminal domain	This is the C-terminal domain of Cas9 enzymes found in actinobacteria [1].	Domain
