UniProtKB description:  Effector DNase of a CBASS antivirus system (PubMed:32544385). CBASS (cyclic oligonucleotide-based antiphage signaling system) provides immunity against bacteriophage. The CD-NTase protein synthesizes cyclic nucleotides in response to infection; these serve as specific second messenger signals. The signals activate a diverse range of effectors, leading to bacterial cell death and thus abortive phage infection. A type II-C(AAAA) CBASS system (PubMed:32839535).
