A compact Druantia defense clears phage infections via single-stranded DNA recognition and directional duplex unwinding

Stephanie Himpich, Thomas Gaudin, Lena M. Grass…·Markus C. Wahl

This paper describes how the Druantia type III-A defense system in E. coli clears phage infections by recognizing single-stranded DNA and unwinding DNA duplexes directionally.

The co-localizing Zorya II, Druantia III, and ARMADA II defense systems on O-island 172 confer synergistic anti-phage defense in enterohemorrhagic Escherichia coli

Huihui Li, Vu Van Loi, Costanza Borelli…·Haike Antelmann

This study identifies that the co-localizing Zorya II, Druantia III, and ARMADA II defense systems on O-island 172 in EHEC confer synergistic anti-phage defense, with Druantia III and ARMADA II providing most of the phage resistance.
