Filing pathway
Alkaloids — 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 other, from MIBiG.
Producer organisms 0
None. The compound has a characterized gene cluster whose host NCBI does not name, which for an uncultured symbiont is the honest state — see the discussion below.
Occurrences 5
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
unnamed-producer — No producer claim is written from BGC0000830, which gives NCBITaxon:77133 (uncultured bacterium — shared by every unplaced bacterium), because the taxon names no single organism. The cluster is kept: a characterized locus is an origin assertion whether or not its host has a name, and for a compound from an uncultured symbiont that is the honest state. Name the producer if the primary literature does.
