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."}],"article_type":"original","date_created":"2024-03-20T10:42:05Z","scopus_import":"1","_id":"15134","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"quality_controlled":"1","oa":1,"status":"public","month":"05","publication":"Nature Communications","oa_version":"Published Version","author":[{"full_name":"Schwartz, Evan A.","last_name":"Schwartz","first_name":"Evan A."},{"first_name":"Tess M.","last_name":"McBride","full_name":"McBride, Tess M."},{"first_name":"Jack Peter Kelly","id":"96aecfa5-8931-11ee-af30-aa6a5d6eee0e","orcid":"0000-0003-0456-0753","last_name":"Bravo","full_name":"Bravo, Jack Peter Kelly"},{"last_name":"Wrapp","full_name":"Wrapp, Daniel","first_name":"Daniel"},{"first_name":"Peter C.","last_name":"Fineran","full_name":"Fineran, Peter C."},{"last_name":"Fagerlund","full_name":"Fagerlund, Robert D.","first_name":"Robert D."},{"last_name":"Taylor","full_name":"Taylor, David W.","first_name":"David W."}],"doi":"10.1038/s41467-022-30402-8","pmid":1,"external_id":{"pmid":["35595728"]},"extern":"1","intvolume":"        13","article_number":"2829","publication_status":"published"}]
