Regulation of bacterial iron homeostasis is often controlled by the iron-sensing ferric uptake repressor (Fur).

Furthermore it also coordinates an iron-sparing response that acts to repress the expression of iron-rich proteins (e.g. succinate dehydrogenase) when iron is limited.

FsrA: a small RNA Represses Expression of Succinate Dehydrogenase

Regulation of bacterial iron homeostasis is often controlled by the iron-sensing ferric uptake repressor (Fur). The Bacillus subtilis Fur protein acts as an iron-dependent repressor for siderophore biosynthesis and iron transport proteins. Furthermore it also coordinates an iron-sparing response that acts to repress the expression of iron-rich proteins (e.g. succinate dehydrogenase) when iron is limited. It has been shown that the downregulation of succinate dehydrogenase (SDH) is most likely caused by complementary binding of a small RNA, named fsrA, to the leader region of the sdhCAB mRNA, namely SdhC' (Fig. 1).
