-        The evolutionary pressure imposed by phage predation on bacteria and archaea has resulted in the development of effective anti-phage defence mechanisms, including restriction–modification and CRISPR–Cas systems. Here, we report on a new defence system, DISARM (defence island system associated with restriction–modification), which is widespread in bacteria and archaea. DISARM is composed of five genes, including a DNA methylase and four other genes annotated as a helicase domain, a phospholipase D (PLD) domain, a DUF1998 domain and a gene of unknown function. Engineering the Bacillus paralicheniformis 9945a DISARM system into Bacillus subtilis has rendered the engineered bacteria protected against phages from all three major families of tailed double-stranded DNA phages. Using a series of gene deletions, we show that four of the five genes are essential for DISARM-mediated defence, with the fifth (PLD) being redundant for defence against some of the phages. We further show that DISARM restricts incoming phage DNA and that the B. paralicheniformis DISARM methylase modifies host CCWGG motifs as a marker of self DNA akin to restriction–modification systems. Our results suggest that DISARM is a new type of multi-gene restriction–modification module, expanding the arsenal of defence systems known to be at the disposal of prokaryotes against their viruses.

 DISARM (Defense Island System Associated with Restriction-Modification) is a defense system widespread in prokaryotes, encoded by a 5-gene cassette. DISARM provides broad protection against double-stranded DNA phages, including siphophages, myophages, and podophages :ref{doi=10.1038/s41564-017-0051-0,10.1101/2021.12.28.474362}.
 
- It was reported to restrict incoming phage DNA and methylate the bacterial host DNA, which could be responsible for self from non-self discrimination :ref{doi=10.1038/s41564-017-0051-0}. This suggests a [Restriction-Modification](/defense-systems/rm)-like (RM-like) mechanism, yet some pieces of experimental evidence hint that DISARM actually acts through a novel and uncharacterized molecular mechanism :ref{doi=10.1038/s41564-017-0051-0,10.1038/s41467-022-30673-1}.

 Yet this system was also shown to protect against phages whose genomes are exempt of CCWGG motifs :ref{doi=10.1038/s41564-017-0051-0}. Moreover, a recent study reports that the absence of methylases (DrmMI or DrmMII) of the DISARM system from a *Serratia sp.* does not result in autoimmunity :ref{doi=10.1101/2021.12.28.474362}. Both these results suggest additional phage DNA recognition mechanisms. 
 
-Hints of these additional mechanisms can be found in recent structural studies, which show that DrmA and DrmB form a complex that can bind single-stranded DNA :ref{doi=10.1038/s41467-022-30673-1}. Moreover, the DrmAB complex seems to exhibit strong ATPase activity in presence of unmethylated DNA, and  reduced ATPase activity in the presence of a methylated DNA substrate :ref{doi=10.1038/s41467-022-30673-1}. Finally, binding of unmethylated single-stranded DNA appears to mediate major conformational change of the complex, which was hypothesized to be responsible for downstream DISARM activation :ref{doi=10.1038/s41467-022-30673-1}.
