Filing pathway
Fatty acids — computed by NPClassifier npclassifier.gnps2.org@2026-09-07, which is why it is pinned rather than recomputed. The gene cluster's asserted class is nrps, from MIBiG.

A claim that this taxon makes the compound. The basis says what the evidence addressed — a knockout and a database assertion are not the same claim.

A locus claim and a taxon claim are different questions. Heterologous expression settles the first and leaves the second where the isolation report left it.
Open questions 1
name-disagreement — ChEBI calls this structure 'GPL-21' and MIBiG calls it 'glycopeptidolipid'. They share a Standard InChIKey, so if the names denote different compounds then one upstream record has the wrong structure. Check which.
