⊟Phenotype[edit | edit source]
IsrR is required for optimum growth in iron-depleted media.
IsrR is required for full virulence in a mouse sepsis model of virulence.
IsrR downregulates nitrite production in anaerobic conditions.
IsrR associates by base-pairing to fdhA, gltB2, narG and nasD mRNAs to downregulate their translation.

- Functional name (symbol): isrR for iron sparing response RNA (Coronel-Tellez et al, 2022).
- IsrR and its regulation by Fur are conserved in the genus Staphylococcus.
- The isrR gene has two Fur boxes and is expressed under low iron growth conditions.
- IsrR has 3 C-rich regions (CRR) involved in pairing with its mRNA targets. Many targets and putative targets of IsrR are mRNAs expressing iron-containing enzymes.
- The putative function of IsrR is to downregulate non-essential iron-containing enzymes in order to spare iron in bacteria. [edit]
