Anti-CRISPR proteins AcrF1/2 bound to Csy surveillance complex with a 20nt spacer crRNA backbone region

Loading... Status: waiting for Mol* initialization Structural highlights 5xlp is a 6 chain structure with sequence from Pseudomonas aeruginosa, Pseudomonas aeruginosa UCBPP-PA14 and Pseudomonas phage JBD30. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Electron Microscopy, Resolution 4.2Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function CSY3_PSEAB CRISPR (clustered regularly interspaced short palindromic repeat) is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids). CRISPR clusters contain sequences complementary to antecedent mobile elements and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). Cas3 and Cascade participate in CRISPR interference, the third stage of CRISPR immunity (Potential). Involved in crRNA production or stability. The Csy ribonucleoprotein complex binds target ssDNA with high affinity but target dsDNA with much lower affinity. See Also CRISPR subtype I-F
