Structural basis for RNA-mediated assembly of type V CRISPR-associated transposons

Authors : Schmitz, Michael (2023)

CRISPR systems have been co-opted by Tn7-like elements to direct RNA-guided transposition. Type V-K CRISPR-associated transposons rely on the concerted activities of the pseudonuclease Cas12k, the AAA+ ATPase TnsC, the Zn-finger protein TniQ, and the transposase TnsB. Here we present a cryo-electron microscopic structure of a target DNA-bound Cas12k-transposon recruitment complex comprising RNA-guided Cas12k, TniQ, TnsC and, unexpectedly, the ribosomal protein ...
