Summary:
Pyoverdines are a group of structurally related siderophores produced by fluorescent Pseudomonas species, in which they provide the primary iron uptake system.

Even though the structures of more than 50 different pyoverdines from different strains and species of Pseudomonas have been determined, they all possess similar structure composed of three parts: a conserved fluorescent dihydroxyquinoline chromophore, an acyl side chain (either dicarboxylic acid or amide) bound to the amino group of the chromophore, and a variable peptide chain linked by an amide group bound to the C1 (rarely C3) carboxyl group of the chromophore [Visca07].

Instances:
ferribactin ,
pyoverdine I

SMILES: C(N[a peptide])(=O)[CH]1(N2(C3(=C(C=C(N[an acyl group])C(NCC1)2)C=C(O)C(O)=C3)))
