Cobalt Targets Multiple Metabolic Processes in Salmonella ...

2007-8-24 · Cobalt is essential for growth of Salmonella enterica and other organisms, yet this metal can be toxic when present in excess. Wild-type Salmonella exhibits several metabolic defects when grown in the presence of cobalt, some of which generate visible growth consequences. Work herein identifies sulfur assimilation, iron homeostasis, and Fe-S cluster metabolism as targets for cobalt toxicity.
