A. AcrIIC3 binds to Nme1Cas9 in the apo, sgRNA-bound, and sgRNA-dsDNA-bound states.
B. Architecture of the Nme1Cas9-sgRNA in complex with AcrIIC3, showing that two AcrIIC3 monomers fasten two Nme1Cas9-sgRNA complexes together.
C. Architecture of the Nme1Cas9-sgRNA in complex with AcrIIC3 and dsDNA, showing that AcrIIC3 does not fully prevent target DNA binding.
