RyhB is a noncoding RNA regulated by the Fur repressor. It has previously been shown to
cause the rapid degradation of a number of mRNAs that encode proteins that utilize iron …

The small RNA RyhB has recently been shown to negatively regulate a number of mRNAs
encoding dispensable iron‐using proteins in Escherichia coli. The resulting decrease in the …

A small RNA, RyhB, was found as part of a genomewide search for novel small RNAs in
Escherichia coli. The RyhB 90-nt RNA down-regulates a set of iron-storage and iron-using …

Iron is one of the most important metals in the metabolism of many organisms, including
bacteria, in which it serves as a cofactor in multiple enzymatic reactions. Most of the earlier …

The Fe2+‐dependent Fur protein serves as a negative regulator of iron uptake in bacteria.
As only metallo‐Fur acts as an autogeneous repressor, Fe2+ scarcity would direct fur …

For most living organisms, iron is both essential and potentially toxic, making the precise
maintenance of iron homeostasis necessary for survival. To manage this paradox, bacteria …

While iron is essential to sustain growth, its excess can be detrimental to the cell by
generating highly toxic reactive oxygen species. Regulation of iron homeostasis thus plays a …

Iron (Fe) is a double‐edged sword for most living organisms. Although it is essential for the
catalytic activity of a large number of enzymes, ferrous iron (Fe2+) becomes cytotoxic in the …

FtnA is the major iron‐storage protein of Escherichia coli accounting for≤ 50% of total
cellular iron. The FtnA gene (ftnA) is induced by iron in an Fe2+–Fur‐dependent fashion …

In many bacteria, iron homeostasis is controlled primarily by the ferric uptake regulator (Fur),
a transcriptional repressor. However, some genes, including those involved in iron storage …
