siderophore production

traitmech:000186 · CLASS · PROPOSED

A physiological trait in which bacteria biosynthesize and release siderophores that scavenge extracellular iron for uptake.

Trait evidence (4)

  • DOI:10.1111/1462-2920.14937
    Siderophores are iron-chelating molecules produced by bacteria to access iron, a key nutrient.

    Schalk et al. define bacterial siderophores as produced iron-chelating molecules that enable iron access.

  • DOI:10.1111/1462-2920.14937
    They are released by bacteria into their environment to scavenge iron and bring it back into the cells.

    The same review supports the release, extracellular scavenging, and uptake clauses in the local definition.

  • DOI:10.15698/mic2018.10.649
    Pyoverdines are fluorescent siderophores of pseudomonads that play important roles for growth under iron-limiting conditions.

    Ringel and Bruser support pyoverdine production as a fluorescent-pseudomonad siderophore-production subtype.

  • DOI:10.1073/pnas.0908760106
    The siderophore pyoverdine (PVD) is a primary virulence factor of the human pathogenic bacterium Pseudomonas aeruginosa

    Imperi et al. support Pseudomonas aeruginosa as a pyoverdine-producing bacterium.

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.

The pinned METPO snapshot contains only METPO:1000277 obsolete siderophore. GO:0019290 is limited to the siderophore biosynthetic process, GO:0015891 is a siderophore transport process, and CHEBI:26672 denotes the siderophore molecule rather than the organism-level biosynthesis-and-release trait.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted siderophore production as a DOI-backed TraitRecord after a repository-wide duplicate review covering ignored and hidden files; METPO has only an obsolete siderophore class in the local snapshot and the replacement placeholder is reserved in proposals/metpo_traitmech_v63.
