Overview

Mode of Action (MoA) binds at the junction between Cas7.6f and Cas8f to inhibit DNA duplex splitting.
Evidence Ectopic expression (ECO_0000017) of AcrIF6 in Pseudomonas aeruginosa resulted in inhibition of type I-F CRISPR-Cas system activity, as demonstrated by restored replication of CRISPR-targeted bacteriophages in plaque assays.
