Visualizing structural dynamics during nuclease activation across evolutionarily diverse IscB and CRISPR-Cas9 enzymes
Abstract Cas9 nucleases of CRISPR-Cas adaptive immune systems are programmable RNA-guided DNA endonucleases that evolved from the transposon-associated IscB enzymes. Comparative structural studies have revealed substantial architectural elaboration during this evolutionary transition, including the replacement of the l...
