{"language":[{"iso":"eng"}],"abstract":[{"text":"CRISPR-Cas systems are adaptive immune systems that protect prokaryotes from foreign nucleic acids, such as bacteriophages. Two of the most prevalent CRISPR-Cas systems include type I and type III. Interestingly, the type I-D interference proteins contain characteristic features of both type I and type III systems. Here, we present the structures of type I-D Cascade bound to both a double-stranded (ds)DNA and a single-stranded (ss)RNA target at 2.9 and 3.1 Å, respectively. We show that type I-D Cascade is capable of specifically binding ssRNA and reveal how PAM recognition of dsDNA targets initiates long-range structural rearrangements that likely primes Cas10d for Cas3′ binding and subsequent non-target strand DNA cleavage. These structures allow us to model how binding of the anti-CRISPR protein AcrID1 likely blocks target dsDNA binding via competitive inhibition of the DNA substrate engagement with the Cas10d active site. This work elucidates the unique mechanisms used by type I-D Cascade for discrimination of single-stranded and double stranded targets. Thus, our data supports a model for the hybrid nature of this complex with features of type III and type I systems.","lang":"eng"}],"keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"date_published":"2022-05-20T00:00:00Z","_id":"15134","year":"2022","day":"20","publication_status":"published","oa_version":"Published Version","type":"journal_article","title":"Structural rearrangements allow nucleic acid discrimination by type I-D Cascade","doi":"10.1038/s41467-022-30402-8","publication_identifier":{"issn":["2041-1723"]},"scopus_import":"1","status":"public","date_created":"2024-03-20T10:42:05Z","publication":"Nature Communications","citation":{"ieee":"E.
