Filing pathway
Polyketides — 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 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.

| Streptomyces neyagawaensis NCBITaxon:42238 |
SOURCE_ASSERTION | mibig:BGC0000040 | PMID:16207901 |
Occurrences 8
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.
