Overview

Mode of Action (MoA) inhibit a broad range of nucleic-acid-targeting defense systems, but MoA is unknown
Evidence Ectopic expression (ECO_0000017) of Bdi1 in Pseudomonas aeruginosa inhibits Zorya type I, RADAR, Hypnos, and Druantia type I antiphage defense systems in plaque formation and culture collapse assays. Site-directed mutagenesis of residues D14A, L33E, and W54A abolishes Bdi1-mediated inhibition of Zorya type I (ECO_0001038).
MoA Category unknown
Subtype(s) of the defence system(s) inhibited by the protein Defence Subtype Druantia type I;Zorya type I;Hypnos;RADAR
