Filing pathway
Carbohydrates — 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 saccharide, from MIBiG.
Producer organisms 5
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.

shared-structure — This structure is reported by more than one MIBiG entry: BGC0000728, BGC0000729, BGC0000730, BGC0000731, BGC0000733. Confirm they describe the same compound rather than an upstream cross-reference error.
