This entry represents the C-terminal domain of CRISPR-associated nuclease/helicase Cas3 subtype I-F/YPEST from Pseudomonas aeruginosa (Cas3), a DNA-degradation enzyme that forms part of the CRISPR-Cas bacterial immune system. Cas3 contains a Cas2 domain, an HD nuclease domain (Pfam:PF18019), RecA1, RecA2, a long linker region, and a C-terminal domain (this entry). This domain contains two alpha-helices and two six-stranded beta-blades [6].	Domain
