Pseudomonas aeruginosa is an opportunistic pathogen which synthesizes two major siderophores, pyoverdine (Pvd) and pyochelin (Pch), to cover its needs in iron(III). Although the high affinity and specificity of Pvd toward iron(III) (pFe = 27.0) is well described in the literature, the physicochem. and coordination properties of Pch toward biol. relevant metals (Fe(III), Cu(II) or Zn(II)) have been scarcely investigated. We report a thorough physico-chem. investigation of Pch (potentiometry, spectrophotometries, ESI/MS) that highlighted its moderate but significantly higher affinity for Fe3+ (pFe = 16.0 at p[H] 7.4) than reported previously. We also demonstrated that Pch strongly chelates divalent metals such as Zn(II) (pZn = 11.8 at p[H] 7....
