This domain is found at the N-terminal end of CRISPR-associated nuclease/helicase Cas3 subtype I-F/YPEST from Pseudomonas aeruginosa and similar sequences predominantly found in proteobacteria. In the type I-F CRISPR-Cas system, Cas3 is fused with Cas2 at the N terminus. This entry represents the Cas2 domain of Cas3, which shows a four-stranded beta-sheet and two alpha-helices, in a structure that resembles that of Cas2 from the Escherichia coli. It appears N- terminal to the histidine-aspartate (HD)-type nuclease domain (Pfam:PF18019) [1,2].	Domain
M, N	PF21802	CRISPR-associated Cas3 subtype I-F/YPEST-like, C-terminal domain (Cas3-like_C)	CRISPR-associated Cas3 subtype I-F/YPEST-like, C-terminal domain	This domain is found at the C-terminal end of CRISPR-associated nuclease/helicase Cas3 subtype I-F/YPEST from Pseudomonas aeruginosa. Cas3 contains an HD nuclease domain (Pfam:PF18019), RecA1, RecA2, a long linker region, and this C-terminal domain. ...	This domain is found at the C-terminal end of CRISPR-associated nuclease/helicase Cas3 subtype I-F/YPEST from Pseudomonas aeruginosa. Cas3 contains an HD nuclease domain (Pfam:PF18019), RecA1, RecA2, a long linker region, and this C-terminal domain. This domain shows two alpha-helices and two six-stranded beta-blades [1,2].	Domain
M, N	PF18019	Cas3, HD domain (Cas3_HD)	Cas3, HD domain	This HD domain is found at the N-terminus of Cas3 enzymes fused to a helicase domain. This domain is sometimes found as a separate protein. It acts as a nuclease that cleaves ssDNA.	Domain
