Anti-CRISPR proteins, illustration

---

Illustration of two anti-CRISPR (Acr) proteins (AcrF1 and AcrF2) bound to a CRISPR RNA-guided surveillance complex. CRISPR-mediated adaptive immune systems are bacterial immune systems that recognise and destroy a viral pathogen's DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) genome. Viruses have evolved their own proteins that target and inhibit CRISPR proteins. AcrF1 and AcrF2 are produced by viruses that attack Pseudomonas sp. bacteria.
