CC -!- FUNCTION: CBASS (cyclic oligonucleotide-based antiphage signaling
CC system) provides immunity against bacteriophage. The CD-NTase protein
CC synthesizes cyclic nucleotides in response to infection; these serve as
CC specific second messenger signals. The signals activate a diverse range
CC of effectors, leading to bacterial cell death and thus abortive phage
CC infection. A type II-C(AAG) CBASS system (PubMed:32839535).
CC {ECO:0000269|PubMed:32544385, ECO:0000303|PubMed:32839535}.
CC -!- FUNCTION: Cyclic trinucleotide synthase that catalyzes the synthesis of
CC 3',3',3'-cyclic AMP-AMP-GMP as the major product, a second messenger
CC for cell signal transduction. {ECO:0000269|PubMed:30787435}.
CC -!- FUNCTION: Protects E.coli against phage T2 infection. When the cdnD-
CC cap2-cap3-cap4 operon is introduced in E.coli there is a more than
CC 10(3) decrease in the efficiency of T2 plaque formation. The operon
CC does not protect against phage T5 and only about 10-fold against T7.
CC {ECO:0000269|PubMed:32544385}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + GTP = cyclic AMP-AMP-GMP + 3 diphosphate;
CC Xref=Rhea:RHEA:60476, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:37565, ChEBI:CHEBI:143810;
CC Evidence={ECO:0000269|PubMed:30787435};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:60477;
CC Evidence={ECO:0000305|PubMed:30787435};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:G2SLH8};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250|UniProtKB:G2SLH8};
CC -!- INDUCTION: Part of the CBASS operon consisting of cap4-cdnD-cap2-cap3.
CC {ECO:0000305|PubMed:32544385}.
CC -!- SIMILARITY: Belongs to the CD-NTase family. D02 subfamily.
CC {ECO:0000305|PubMed:30787435}.
