The bacterial Cyclic-oligonucleotide-Based Anti-phage Signaling System (CBASS) contains a CD-NTase that synthesizes cyclic di- and tri-nucleotides, and bacterial STING proteins recognize c-di-GMP generated by CD-NTase during phage infection and signal the infected bacteria to commit suicide. Here, the authors provide insights into the molecular basis for c-di-GMP recognition of bacterial STING proteins by determining two STING protein crystal structures with bound c-di-GMP from Prevotella corporis and Myroides sp. ZB35.
