Apyc1 |
pyrimidine cyclase system for antiphage resistance (Pycsar) |
CLAN001 |
Bsp38 of Bacillus subtilis |
PMID:35395152 |
SBSphiJ Apyc1 efficiently hydrolyses a wide range of cyclic mononucleotides; 273 Acb1 and 107 Apyc1 phage proteins were identified. |

CLAN004 |
phi3T of B. subtilis |
Yirmiya et al., 2023 Antine et al., 2023 |
Gad1 forms an octameric web that encases the GajAB complex and inhibits DNA recognition and cleavage. |

Gad2 |
Gabija |
CLAN007 |
SPbetaL7 of B. subtilis |
Yirmiya et al., 2023 |
Alphafold2 predicted that Gad2 is an enzyme with a nucleotidyltransferase protein domain, suggesting that it inhibits Gabija via a mechanism of action different than Gad1. |

Tad1 |
Thoeris |
CLAN023 |
SBSphiJ7 of B. subtilis |
PMID:36174646 |
Tad1 proteins are not an enzymes, but are 'sponges' that bind and sequester the immune signaling molecule (cyclic ADP-ribose or gcADPR) produced by TIR-domain proteins, thus decoupling phage sensing from immune effector activation and rendering Thoeris inactive. |

Had1 |
Hachiman |
CLAN024 |
SBSphiJ4 of B. subtilis |
Yirmiya et al., 2023 |
Had1 (Hachiman anti-defense 1) is a Hachiman-inhibiting family of phage proteins. The mechanism of Hachiman defense is unknown. |
| APIS027 |
DSAD1 |
defence-associated sirtuin (DSR) |
CLAN026 |
SPbeta phages of B. subtilis |
PMID:36192536 |
DSAD1 is a phage anti-DSR2 protein that binds and inhibits Defence-associated sirtuins (DSR2). In bacteria, N-terminal sirtuin (SIR2) domains within DSR2 were shown to participate in defence systems including prokaryotic argonautes (pAgo), Thoeris, AVAST, defence-associated sirtuin (DSR), etc. |

Tad2 |
Thoeris |
CLAN023 |
Bacillus phage SPO1 |
Yirmiya et al., 2023 |
Tad2 is a "sponge" that sequesters the immune signaling molecules produced by Thoeris TIR-domain proteins in response to phage. |

MpaR |
SOS response |
CLAN041 |
prophage of Listeria monocytogenes 10403S |
PMID:31754112 |
MpaR plays a critical role in the de-repression (induction) of the two phage elements and is sufficient for ϕ10403S induction. |

AriS |
SOS response |
CLAN060 |
prophage of Listeria monocytogenes 10403S |
PMID:35443160 |
LMRG_02920 (AriS) encodes in prophage L. monocytogenes strain 10403S. It acts as a RecA inhibitor and inhibits the bacterial SOS response. |
