The results of this study show a previously unidentified connection between arginine metabolism, siderophore turnover, and oxidative stress inPseudomonas putida . Although the precise molecular mechanisms involved have yet to be characterized in full detail, our data are consistent with a model in which arginine biosynthesis and the derived pathway leading to polyamine production function as a homeostasis mechanism that helps maintain the balance between iron uptake and oxidative-stress response systems.
