Kranzusch, Gil Amitai, Rotem Sorek* INTRODUCTION: Many innate immune pathways in bacteria, plants, and animals use nucleotide derivatives as intracellular immune signaling molecules. Phages have evolved counterdefense “sponge” proteins that inhibit bacterial immune signaling by binding and sequestering the immune signals as well as enzymes that can cleave and inactivate the signaling molecules. A few antidefense sponge and enzyme protein families were recently discovered serendipitously, suggesting that they are abundant among phages. …
