PF22335Cas10/Cmr2, second palm domain (Cas10-Cmr2_palm2)Cas10/Cmr2, second palm domainThis entry represents the second palm domain of Cas10 subunit (named Csm1 in Type III-A and Cmr2 in III-B systems) from type III CRISPR-Cas systems [6]. This domain contains a conserved GGDD motif that is important for DNA polymerase activity [1-5]. ...Domain
PF18211Csm1 subunit domain B (Csm1_B)Csm1 subunit domain BThis domain is found in the Csm1 subunit of the Csm complex found in Thermococcus onnurineus. Csm is a type III-A CRISPR-Cas system, which is an RNA-guided immune defense mechanism that detects and destroys foreign DNA or RNA. This domain is known as ...Domain
PF20824CRISPR RNA silencing complex Cmr2 subunit, second helical domain (Cmr2_hel_dom2)CRISPR RNA silencing complex Cmr2 subunit, second helical domainThe prokaryotic CRISPR RNA-Cas protein (Cmr) complex provides protection against mobile genetic elements by cleaving foreign RNA. Its largest subunit is Cmr2. This protein shows a N-terminal HD (histidine-aspartate) domain, two RRM domains resembling ...Domain
