Structural basis for inhibition of SpyCas9 by the anti-CRISPR protein AcrIIA26
{{output}}
CRISPR-Cas9 systems provide adaptive immunity in prokaryotes by targeting and cleaving invading phage DNA. In response, phages have evolved anti-CRISPR (Acr) proteins to inhibit Cas9 and evade this immune response. AcrIIA26 is a type II-A anti-CRISPR protein t... ...
