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