Pyoverdine (or pyoverdin) is a fluorescent siderophore produced by the Gram negative bacterium Pseudomonas aeruginosa.[1]

In Pseudomonas aeruginosa PAO1 there are 14 pvd genes involved in the synthesis of the pyoveridine.[2]

Unlike Enterobactin, Pyoverdine/pseudobactins are iron-binding non-ribosomal peptides containing a dihydroxyquinoline derivative. The structure of the peptide differs between pseudomonads and over 40 structures have been described, while the chromophore, (1S)-5-amino-2,3-dihydro- 8,9-dihydroxy-1H-pyrimido[1,2-a]quinoline-1-carboxylic acid, is the same with the exception of azobactin from Azotobacter vinelandii, which possesses an extra urea ring.[3]

Structure of the peptide backbone in various fluorescent Pseudomonas strains. Amino acid three-letter code are used along with Q=chromophore, DXxx=D amino acid, aThr=allo-threonine, c=cyclic structure, cOHOrn=cyclo-hydroxyornithine, Dab=diaminobutyric acid, Ac=Acetyl, Fo=formyl OH=hydroxyl[3]
