Structural and dynamic insights into the role of conformational switching in the nuclease activity of the Xanthomonas albilineans Cas2 in CRISPR-mediated adaptive immunity
Clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR-associated (Cas) proteins constitute a microbial, adaptive immune system countering invading nucleic acids. Cas2 is a universal Cas protein found in all types of CRISPR-Cas systems, and its role is implicated in new spacer acquisition into CRISPR loci. In subtype I-C CRISPR-Cas systems, Cas2 proteins are metal-depend...
متن کاملWhat makes Xanthomonas albilineans unique amongst xanthomonads?
Xanthomonas albilineans causes leaf scald, a lethal disease of sugarcane. Compared to other species of Xanthomonas, X. albilineans exhibits distinctive pathogenic mechanisms, ecology and taxonomy. Its genome, which has experienced significant erosion, has unique genomic features. It lacks two loci required for pathogenicity in other plant pathogenic species of Xanthomonas: the xanthan gum biosy...
متن کاملTotal synthesis of albicidin: a lead structure from Xanthomonas albilineans for potent antibacterial gyrase inhibitors.
The peptide antibiotic albicidin, which is synthesized by the plant pathogenic bacterium Xanthomonas albilineans, displays remarkable antibacterial activity against various Gram-positive and Gram-negative microorganisms. The low amounts of albicidin obtainable from the producing organism or through heterologous expression are limiting factors in providing sufficient material for bioactivity pro...
متن کاملCas1 and the Csy complex are opposing regulators of Cas2/3 nuclease activity.
The type I-F CRISPR adaptive immune system in Pseudomonas aeruginosa (PA14) consists of two CRISPR loci and six CRISPR-associated (cas) genes. Type I-F systems rely on a CRISPR RNA (crRNA)-guided surveillance complex (Csy complex) to bind foreign DNA and recruit a trans-acting nuclease (i.e., Cas2/3) for target degradation. In most type I systems, Cas2 and Cas3 are separate proteins involved in...
متن کاملStaphylococcal nuclease: sequential assignments and solution structure.
Sequential assignments are reported for backbone 15N and 1H of nearly all residues of staphylococcal nuclease (Nase) complexed with thymidine 3',5'-diphosphate and Ca2+. Because of the relatively large size of the Nase ternary complex, Mr 18K, the crucial element of our assignment strategy was the use of isotope-edited two-dimensional NMR spectra, particularly 15N-edited nuclear Overhauser enha...
