While a myriad of CRISPR-Cas systems have been identified to date, type I-C is one of the most commonly found subtypes in nature. Interestingly, the type I-C system employs a minimal Cascade effector complex, which encodes only three unique subunits in its operon. Here, we present a 3.1 Å resolution cryo-EM structure of the <jats:italic>Desulfovibrio vulgaris</jats:italic> type I-C Cascade, revealing the molecular mechanisms that underlie RNA-directed complex assembly. We demonstrate how this minimal Cascade utilizes previously overlooked, non-canonical small subunits to stabilize R-loop formation. Furthermore, we describe putative PAM and Cas3 binding sites. These findings provide the structural basis for harnessing the type I-C Cascade as a genome-engineering tool."}],"publication":"Nature Communications","intvolume":"        11","type":"journal_article","day":"23","doi":"10.1038/s41467-020-19785-8","pmid":1,"month":"11","external_id":{"pmid":["33230133"]},"article_type":"original","oa_version":"Published Version","extern":"1","oa":1,"publication_status":"published","author":[{"last_name":"O’Brien","full_name":"O’Brien, Roisin E.","first_name":"Roisin E."},{"first_name":"Inês C.","last_name":"Santos","full_name":"Santos, Inês C."},{"first_name":"Daniel","last_name":"Wrapp","full_name":"Wrapp, Daniel"},{"last_name":"Bravo","full_name":"Bravo, Jack Peter Kelly","id":"96aecfa5-8931-11ee-af30-aa6a5d6eee0e","orcid":"0000-0003-0456-0753","first_name":"Jack Peter Kelly"},{"full_name":"Schwartz, Evan A.","last_name":"Schwartz","first_name":"Evan A."},{"full_name":"Brodbelt, Jennifer S.","last_name":"Brodbelt","first_name":"Jennifer S."},{"full_name":"Taylor, David W.","last_name":"Taylor","first_name":"David W."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41467-020-19785-8"}],"article_processing_charge":"Yes","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"date_updated":"2024-06-04T05:52:51Z","date_published":"2020-11-23T00:00:00Z","publisher":"Springer Nature","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":11,"status":"public"}
