Lamassu-Lipase system

traitmech:000562 · CLASS · PROPOSED

A Lamassu system in which an organism possesses a genome-encoded DefenseFinder Lamassu-Lipase subtype locus represented by the Lamassu-Lipase rule row requiring the Lamassu-Fam__LmuA_effector_Lipase and Lamassu-Fam__LmuB_SMC_Cap4_nuclease_II profiles.

Lamassu-Lipase is a DefenseFinder Lamassu subtype

Conservative subtype-level classification linking the DefenseFinder Lamassu-Lipase rule-row definition to Lamassu-Lipase system possession and its Lamassu parent.

NONMECHANISTIC · The graph captures Lamassu-Lipase as a DefenseFinder rule-row subtype of Lamassu system possession without asserting a Lamassu-Lipase-specific antiphage process, selecting between the rule-row LmuB profile and the Lipase-scoped LmuB HMM row, or resolving exact phage-triggered substrate chemistry, viral-DNA trigger, LmuC requirement, native host breadth, cell-death output, or whether every DefenseFinder Lamassu-Lipase prediction is a complete experimentally active locus.

Lamassu-Lipase is a DefenseFinder Lamassu subtype Interactive directed graph showing evidence-backed causal relationships for Lamassu-Lipase system.

Attached to causal_graphs#lamassu_lipase_locus_subtype_defense

Haudiquet et al. support a Lamassu family with diverse LmuA effectors and a conserved SMC-like sensor, and the pinned DefenseFinder HMM inventory and rules table support Lamassu-Lipase as a Lamassu-Fam subtype whose rule row requires Lamassu-Fam__LmuA_effector_Lipase and Lamassu-Fam__LmuB_SMC_Cap4_nuclease_II. This first-pass record follows the rule row but leaves the relationship between its LmuB Cap4-nuclease profile name and the Lipase-scoped Lamassu-Fam__LmuB_SMC_Lipase HMM row unresolved, along with exact lipase substrates, LmuC requirement, native hosts, phage triggers, cell-death output, and profile-to-activity criteria.

Evidence

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted Lamassu-Lipase system as a DefenseFinder-backed GENOMICS TraitRecord under the Lamassu system parent after an ignored-and-hidden duplicate review found no exact live TraitMech, METPO, history, or prior proposal record for the target local ID, placeholder METPO ID, proposal cohort, record slug, human label, or DefenseFinder subsystem; existing Lamassu-Fam__LmuA_effector_Lipase mentions were limited to forbidden-profile evidence on neighboring Lamassu-Fam subtypes, and the replacement placeholder is reserved in proposals/metpo_traitmech_v439.

  2. · REVIEW_CANONICAL_EXAMPLE_EVIDENCE_GAP · codex

    Reviewed Lamassu-Lipase system during initial curation and left canonical_examples empty because the pinned DefenseFinder tables support a rule-row subtype but not an accession-backed native microbial taxon exemplar tied to the Lamassu-Lipase profiles and experimentally verified endogenous activity. No paid research was used.
