Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.
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.
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 dom ...
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].
