Family :

RyhB

Id:

RF00057

Type:

Gene; sRNA;

Taxonomy:

Eukaryota; Bacteria;

Ontology:

Not found

Description:

The RyhB 90-nt RNA down-regulates a set of iron-storage and iron-using proteins when iron is limiting;
it is itself negatively regulated by the ferric uptake repressor protein, Fur (Ferric uptake regulator).
RyhB RNA levels are inversely correlated with mRNA levels for the sdhCDAB operon, encoding succinate
dehydrogenase, as well as five other genes previously shown to be positively regulated by Fur
by an unknown mechanism. These include two other genes encoding enzymes in the tricarboxylic acid
cycle, acnA and fumA, two ferritin genes, ftnA and bfr, and a gene for superoxide
dismutase, sodB [1]. This ncRNA gene was recently identified in a screen and called SraI
and was found to be expressed only in stationary phase [2].
