Evidence (2)
Imported from microbedecoder via ols-label-exact-chebi. source_id=kgmicrobe.trait:threonine;
Added 'DL-threonine' as a RELATED_SYNONYM (#260): the racemate under the stereo-unspecified parent — the same treatment `DL-Tyrosine` gets in this batch, except that CHEBI:26986 is already held by this record, so it is a synonym rather than a new one. RELATED rather than EXACT because the racemate is narrower than the parent. NOT CHEBI:16857 L-threonine, which CultureMech asserts (CultureMech#276). CultureMech uses this surface form and label_index did not contain it, so the lookup missed. No new record: CHEBI:26986 is this record's identifier, and in MIM the identifier IS the ontology CURIE, so a second record on it would be a duplicate primary key rather than added coverage.
