uses as electron donor

METPO:2000009 · OBJECT_PROPERTY · REVIEWED

An OBJECT_PROPERTY relating an organism to a chemical entity (e.g. a CHEBI class) that the organism oxidises as an electron donor for energy conservation or biosynthetic reductant. The intended use is predicate + class composition at assertion time, e.g. `<organism> METPO:2000009 CHEBI:18276` ("organism uses molecular hydrogen as electron donor").

2026-05-10T00:00:00-07:00 · DEPRECATED_PROPERTY_RECORD · codex
Deprecated generic chemical-use relation carrier; later replacement should use more specific trait records that combine the relation with the chemical, metabolic role, growth condition, and positive or negative usage context.
2026-05-16T08:00:00-07:00 · UNDEPRECATED_AS_COMPOSITION_PRIMITIVE · claude
Restored from DEPRECATED to REVIEWED. METPO modeling uses the predicate + class composition pattern (this OBJECT_PROPERTY composed with a CHEBI electron-donor chemical at assertion time) rather than precomposed substrate-specific TraitRecords. Added DOI-backed definition and evidence.
2026-05-17T10:00:00-07:00 · ADDED_EXTERNAL_PREDICATE_XREF · claude
Added xrefs ['MICRO:0001462'] to record an external equivalence predicate (MICRO:0001462 'uses electron donor'). MICRO:0001462 'uses electron donor' is the direct equivalent. Source: OLS4 property search.
