Producer organisms

Organisms that biosynthesize this compound. Cluster link evidence is how the upstream source graded the gene cluster, so it is populated only for a source that grades it. An empty cell is not weaker support: a curator-authored producer carries its support in Evidence instead. Where the source entry named several compounds, the evidence is marked inherited, meaning it covers this compound together with the cluster's other products rather than singling it out. Those products need not be related to each other: a cluster can list an intermediate, a precursor and a finished antibiotic side by side.
