curacomycin
CHEBI:156426 EXACT SEEDED antibacterial
A homodetic cyclic peptide found in several Streptomyces species, consisting of 3-hydroxyasparagine, L-ornithine, L-isoleucine, D-leucine, D-valine and 5-chloro-L-tryptophan joined in sequence in a cyclic arrangement by peptide linkages. It exhibits antibacterial properties.

Filing pathway
Amino acids and peptides — 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, 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.

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.
