traitmech:000312 · CLASS · PROPOSED

A phage defense system in which an organism possesses an Audmula locus that can restrict bacteriophage infection.

Trait evidence (3)

  • DOI:10.1093/nar/gkae671
    These systems were named after cheese, cattle or fermentation related deities (Rhea, Aristaios, Kamadhenu, Fliodhais, Audmula, Rugutis and Hesat)

    Grafakou et al. named Audmula among seven not previously described lactococcal antiphage systems.

  • DOI:10.1073/pnas.2426508122
    we isolated 66 phage escape mutants which had become insensitive to 13 distinct, plasmid-encoded lactococcal phage resistance systems (i.e. Rhea, Kamadhenu, Rugutis, Audmula, PARIS, type II CBASS, Septu, AbiA, AbiB, AbiD/F, AbiG, AbiJ, AbiP)

    Mosterd et al. later included Audmula among the distinct plasmid-encoded lactococcal phage-resistance systems investigated by phage escape-mutant isolation.

    Audmula | 10\.1093/nar/gkae671 | Discovery of antiphage systems in the lactococcal plasmidome

    The DefenseFinder article registry maps the named Audmula system to the Grafakou et al. lactococcal antiphage-system discovery paper.

Audmula loci confer bacterial phage defense

Conservative system-level sketch linking possession of an Audmula locus to restricted bacteriophage propagation without asserting the unresolved phage trigger or molecular output.

NONMECHANISTIC · The graph captures Audmula as a named lactococcal anti-phage system while leaving its direct phage trigger, molecular substrate, antiviral effector output, natural locus breadth, and the absence of pinned DefenseFinder HMM or rule rows unresolved.

Edge evidence

  • Audmula locus contributes to restricted phage propagation RO:0002326

    The lactococcal plasmidome screen discovered Audmula as a named antiphage system, and the DefenseFinder article registry maps the Audmula system to that discovery paper.

Attached to causal_graphs#audmula_locus_restricts_phage

Grafakou et al., Mosterd et al., and DefenseFinder support Audmula as a named anti-phage system, but the direct trigger, molecular substrate, antiviral effector output, natural locus breadth, and profile-to-component model are not resolved enough here to assert a narrower mechanistic child trait.
