    Our integrative analysis reveals that sulfur starvation critically regulates iron homeostasis by linking reduced Fe uptake to the induction of antioxidant defenses. This iron-buffering response likely mitigates oxidative damage from unincorporated Fe, representing a protective metabolic adaptation. Additionally, the concurrent attenuation of virulence pathways suggests that targeting sulfur metabolism could disrupt iron-dependent virulence gene regulation, offering therapeutic insights into nutritional immunity strategies. Collectively, our findings uncover a novel sulfur-iron axis that plays a central role in oxidative stress management and pathogenicity modulation in bacteria.
