On the other hand, excess of iron could lead to formation of ROS, which could be toxic for the cell. Therefore, microorganisms have established a tight control on the intracellular iron content. The milestone of the bacterial iron-dependent response is the ferric uptake regulator (Fur) protein. In silico, biochemical and in vivo studies established the role of CAC1682 as a genuine iron-responsive regulator in the solvent-producing bacterium Clostridium acetobutylicum.
