CvkR is a MerR-type transcriptional repressor of class 2 type V-K CRISPR-associated transposase systems
…and indirectly the abundance of the tracr-CRISPR RNA. We identify a widely conserved CvkR binding motif 5’-AnnACATnATGTnnT-3’. Crystal structure of CvkR at 1.6 Å resolution reveals that it comprises distinct…
