Chemical inhibition of a bacterial immune system
Small molecules inhibit type II Thoeris anti-phage systems from diverse bacteria. One compound, IP6C, improves phage-therapy against P. aeruginosa & is effective against Thoeris in polymicrobial communities

Bacterial defense via RES-mediated NAD+ depletion is countered by phage phosphatases
Many bacterial defense systems restrict phage infection by breaking the molecule NAD+ to its constituents, adenosine diphosphate ribose (ADPR) and nicotinamide (Nam). To counter NAD+ depletion-mediated defense, phages evolved NAD+ reconstitution pathway 1 (NARP1), which uses ADPR and Nam to rebuild NAD+. Here we report a bacterial defense system called aRES, involving RES-domain proteins that degrade NAD+ into Nam and ADPR-1″-phosphate (ADPR-1P). This molecule cannot serve as a substrate for NARP1, so that NAD+ depletion by aRES defends against phages even if they encode NARP1. We further discover that some phages evolved an extended NARP1 pathway capable of overcoming aRES defense. In these phages, the NARP1 operon also includes a specialized phosphatase, which dephosphorylates ADPR-1P to form ADPR, a substrate from which NARP1 then reconstitutes NAD+. Other phages encode inhibitors that directly bind aRES proteins and physically block their active sites. Our study describes new layers in the NAD+-centric arms race between bacteria and phages and highlights the centrality of the NAD+ pool in cellular battles between viruses and their hosts. ### Competing Interest Statement The authors have declared no competing interest.

A methylome-derived m6-dAMP trigger assembles a PUA-Cal-HAD immune filament that depletes dNTPs to abort phage infection
Bacteria must distinguish phage attack from normal homeostatic processes, yet the danger signals that trigger many defence systems remain unknown. Here, we show that a PUA-Calcineurin-CE-HAD module from Escherichia coli ECOR28 confers broad anti-phage protection by binding Dam-methylated deoxyadenosine monophosphate (m6-dAMP) generated during phage-induced chromosome degradation. Ligand binding converts a preassembled PUA-Calcineurin-CE hexamer loaded with six HAD phosphatases into a polymerising filament. The filament acts as a high-flux dNTP sink through a two-enzyme cascade: HAD first dephosphorylates dATP to dADP, and Calcineurin-CE then converts dADP to dAMP. dNTP collapse halts phage replication and enforces abortive infection. Multiple mobile-element DNA mimic proteins block filament assembly, revealing a direct phage counter-defence. More broadly, our findings extend a conserved, cross-kingdom paradigm of immune filament assembly to nucleotide-depletion antiviral defence and suggest modified-nucleotide sensing by related PUA-Calcineurin-CE modules as a widespread, underappreciated bacterial strategy. ### Competing Interest Statement The authors have declared no competing interest.

Preprint out: We characterise PUA-Cal-HAD, a widespread bacterial antiphage defence family. An infection cue switches a preassembled complex into an immune filament that drains dNTPs via a coupled two-enzyme cascade, and phage DNA mimics can block filament assembly (anti-polymerisation).
