[Characterization of the fluorescent pigment pyoverdine Pm, produced by Pseudomonas putida bacteria].
It has been shown that under iron-limited conditions Pseudomonas putida M produces large amounts of the fluorescent pigment, pyoverdine Pm, which is a siderophore and exhibits antibacterial activity. The absorption spectrum for the pyoverdine Pm has two main peaks, at 230 nm and 400 nm, respectively. It was demonstrated that pyoverdine Pm molecule besides dihydroxyquinoline moiety has a peptide chain contain five amino acids: threonine, serine, lysine, hydroxyaspartic acid and N delta-hydroxyornithine in a molar ratio 3:2:1:1:1.
