CHEBI:71609 EXACT SEEDED
A member of the class of 2,5-diketopiperazines that is piperazine-2,5-dione in which the two hydrogen at position 3 and those at position 6 are replaced by benzylidene and isobutylidene groups (the 3Z,6Z-geoisomer).

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 other, 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 noursei ATCC 11455 NCBITaxon:316284 |
SOURCE_ASSERTION | mibig:BGC0000851 | PMID:12498889 |
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.
