Abstract
Metalloregulatory proteins allow cells to sense metal ions and appropriately adjust the expression of metal uptake, storage, and efflux pathways. Bacillus subtilis provides a model for the coordinate regulation of iron and manganese homeostasis that involves three key regulators: Fur senses iron sufficiency, MntR senses manganese sufficiency, and PerR senses the intracellular Fe/Mn ratio. Here, I review the structural and physiological bases of selective metal perception, the effects of non-cognate metals, and mechanisms that may serve to coordinate iron and manganese homeostasis.Entities:
