gelatinase activity

traitmech:000136 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active gelatinase protease.

Trait evidence (2)

  • DOI:10.1128/JB.01311-07
    One of the well-studied virulence factors of Enterococcus faecalis is a secreted bacterial protease, termed gelatinase

    Del Papa et al. identify Enterococcus faecalis gelatinase as a secreted bacterial protease and experimentally test maturation steps needed for full protease activity.

  • DOI:10.1128/IAI.73.3.1606-1612.2005
    all gelatinase-positive isolates but little to no translocation for gelatinase nonproducers

    Zeng, Teng and Murray score Enterococcus faecalis isolates by gelatinase production and distinguish gelatinase-positive from gelatinase-negative phenotypes.

Resolve an exact external ontology class for gelatinase activity before adding a TraitRecord xref.

CURATION TODO OPEN gelatinase-activity-xref-gap · raised by codex · 2026-09-11

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

GO:0008233 is the generic peptidase-activity class and MICRO:0000649 denotes a gelatinase assay, so both are too broad or assay-level for equivalent TraitRecord xrefs.
