To overcome these defense systems, phages and viruses have developed inhibitors called anti-CRISPRs (Acrs) that are capable of inhibiting the host CRISPR-Cas system via different mechanisms. Although the inhibitory mechanisms of AcrIIC1, AcrIIC2, and AcrIIC3 have been revealed, the inhibitory mechanisms of AcrIIC4 and AcrIIC5 have not been fully understood and structural data are unavailable. In this study, we elucidated the crystal structure of Type IIC anti-CRISPR protein, AcrIIC4. Our structural analysis revealed that AcrIIC4 exhibited a helical bundle fold comprising four helixes. Further biochemical and biophysical analyses showed that AcrIIC4 formed a monomer in solution, and monomeric AcrIIC4 directly interacted with Cas9 and Cas9/sgRNA complex. Discovery of the structure of AcrIIC4 and their interaction mode on Cas9 will help us elucidate the diversity in the inhibitory mechanisms of the Acr protein family.
