VP1853 system

traitmech:000492 · CLASS · PROPOSED

A phage defense system in which an organism possesses a VP1853-family locus represented by the DefenseFinder VP1853__VP1853 custom HMM profile and experimentally linked to reduced bacteriophage plaquing when the cloned Vibrio parahaemolyticus RIMD 2210633 vp1853 cassette is expressed from a VSV105 plasmid.

VP1853 loci reduce bacteriophage plaquing

Conservative system-level sketch linking VP1853-family locus possession to reduced bacteriophage plaquing without resolving VP1853 component function or molecular output.

NONMECHANISTIC · The graph captures VP1853 as a RIMD 2210633 integron cassette with cloned phage-plating readouts, a PSI-BLAST homolog lead, one pinned DefenseFinder custom HMM-profile row, and no pinned DefenseFinder rule row. It does not assert native host breadth, exact profile-to-protein correspondence, molecular activity, phage trigger, substrate, complete homolog boundary, endogenous activity, or rule-level DefenseFinder detection criteria.

Attached to causal_graphs#vp1853_locus_reduces_bacteriophage_plaquing

Getz et al. support VP1853 as one of nine RIMD 2210633 integron-encoded cassettes whose cloned expression reduced phage plaquing, Supplementary Tables 8, 9, and 12 map VP1853 to VP_RS09025/Vp1853, WP_005483178.1, VSV105-vp1853, and a phage-plating fold change, and Supplementary Data 1 reports PSI-BLAST homologs. The pinned DefenseFinder HMM inventory records one VP1853 custom profile row. The pinned rules table has no VP1853 row, and the first-pass record does not resolve native host breadth, complete phage breadth, direct profile-to-protein correspondence, molecular output, or endogenous activity.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted VP1853 system as a DOI-backed GENOMICS TraitRecord under phage defense system after an ignored-and-hidden duplicate review found no exact same-scope live TraitMech, METPO, history, or prior proposal record; kept the graph at cloned integron-cassette level because molecular output, native activity, and rule rows remain unresolved; proposals/metpo_traitmech_v369 reserves the replacement placeholder.

  2. · REVIEW_CANONICAL_EXAMPLE_EVIDENCE_GAP · codex

    Reviewed VP1853 system canonical_examples and left them empty because Getz et al. directly support cloned VP1853 VSV105-plasmid assays, PSI-BLAST homologs, and a DefenseFinder VP1853 model, but not a direct named native microbial isolate exemplar with experimentally verified endogenous VP1853 activity. No paid research was used.
