Pyoverdine is a complex of polar yellow-green pigments first reported by Gessard, Pasteur Institute, France in 1892. The pigment class comprises >100 analogues produced by a large number of Pseudomonas strains, with Pyoverdine Group I produced by Pseudomonas aeruginosa PA01. Structurally pyoverdine group I is an octapeptide bound to a 2,3-diamino-6,7-dihydroxyquinoline derived chromophore. The core structure is coupled to a Krebbs cycle acid (succinate, fumarate, malate etc.). Pyoverdine is a primary virulence factor of the human pathogenic bacterium Pseudomonas aeruginosa, acting as a siderophore and a virulence-related signal molecule. Pyoverdine plays an important role for the bacterial growth under iron-limited conditions. Source: Pseudomonas sp.
