Unclassified — 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, pks, from MIBiG.

Producer organisms 1

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.

Somebody found the compound in this organism and cited it. That is not a claim that the organism makes it, and nothing here promotes one to the other.

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 'romidepsin' and MIBiG calls it 'FR901228'. They share a Standard InChIKey, so if the names denote different compounds then one upstream record has the wrong structure. Check which.
