naturalproductmech:mibig-8220bd1a70 MINTED SEEDED

Grounding review: No 3-star ChEBI entry shares this structure, so the record keeps a content-hashed identifier.

What these status tags mean

Curation status describes a workflow state. SEEDED means the record entered through the source-seeding workflow; it does not imply that no later curation occurred. PROPOSED marks an addition awaiting review; REVIEWED records curator sign-off on identity, structure, filing class and producer claims; DEPRECATED retains a superseded or out-of-scope record. These are workflow decisions, not independently verified human review. Agent-assisted contributions may appear in the record history.

Grounding describes the identifier mapping: EXACT uses an ontology identity asserted by the source; MINTED keeps a local identifier when no defensible ontology identity is available; REVIEW_NEEDED flags an exact structure whose ontology identity needs adjudication. The grounding note retains any unresolved alternatives. These tags do not establish the strength of producer or activity evidence.

Structure

Standard InChIKey	IDDKYWGBXFPXSV-JLVGNTQSSA-N
SMILES	O=C(CNC([C@](O)(C)C1=O)=O)NC(/C=C/C(N(C)CC(O[C@@H](CCCCCCCCCCCCCC)[C@@H]1C)=O)=O)=C
Stereochemistry	fully defined

Filing pathway

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 nrps, pks, from MIBiG.

Producer organisms 2

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.

Taxon	Basis	Cluster	Evidence
Micromonospora sp. RV43 NCBITaxon:1661387	SOURCE_ASSERTION	mibig:BGC0001330	PMID:26637117
Salinispora arenicola CNR107 NCBITaxon:1169167	SOURCE_ASSERTION	mibig:BGC0001331	PMID:28221346

Occurrences 1

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.

shared-structure — This structure is reported by more than one MIBiG entry: BGC0001330, BGC0001331. Confirm they describe the same compound rather than an upstream cross-reference error.
