Overview

Mode of Action (MoA) AlphaFold 3 predicts high-confidence interactions between Cas5e (https://www.ncbi.nlm.nih.gov/protein/QZE32570.1) and AcrIE5 (ipTM = 0.81, pTM = 0.86).
Evidence In Pseudomonas aeruginosa strains ectopically expressing AcrIE5 (ECO_0000017) and harboring active type I-E CRISPR-Cas targeting phage JBD8, phage replication was restored, demonstrating CRISPR inhibition. Binding it supported by computational structure modeling evidence (ECO_0006368).
