CHEBI:45257 EXACT SEEDED antibacterial

An amino cyclitol glycoside that is 4,6-diaminocyclohexane-1,2,3-triol having a 2,6-diamino-2,6-dideoxy-α-D-glucosyl residue attached at position 1 and a β-D-ribosyl residue attached at position 2. It is an antibiotic produced by Streptomyces ribosidificus (formerly S. thermoflavus).

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 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.

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.
