Phages often degrade the genome of their bacterial host to individual nucleotides. Here we describe Metis, a bacterial defense system that directly senses phage-mediated host genome degradation. Metis...

Arbitrium phages belonging to different species and genera can influence each other’s infection dynamics by secreting chemically similar, non-cognate signal peptides. These findings indicate that arbi...

In this issue of Cell Host & Microbe, Osterman et al. discover aRES, a new family of bacterial immune proteins that deplete cellular NAD+, generating cleavage products that cannot be utilized by canon...

A functional screen reveals phage sponge proteins that bind Pycsar, Thoeris and CBASS signalling molecules to inhibit bacterial immunity.

Many bacterial defense systems restrict phage infection by breaking down the molecule nicotinamide (Nam) adenine dinucleotide (NAD+) into adenosine di…
