Ferric Uptake Regulator (FUR) protein: properties and

9 hours ago Annalsmicrobiology.biomedcentral.com Show details

The Ferric uptake regulator (Fur) protein is a global iron regulator found in most prokaryotes. Although the Fur protein is involved in a variety of metabolic pathways, it is specifically known for the regulation of several iron responsive genes. It binds to the highly conserved sequences located in the upstream promoter region known as iron boxes, using ferrous ion as a co-repressor.

Transcriptional regulation by Ferric Uptake Regulator (Fur

6 hours ago Frontiersin.org Show details

Ferric Uptake Regulator (Fur) is a transcription factor which utilizes Fe2+ as a corepressor and represses siderophore synthesis in pathogens. Fur, directly or indirectly, controls expression of enzymes that protect against ROS damage. Thus, the challenges of iron homeostasis and defense against ROS are addressed via Fur.

Frequently Asked Questions

Which is a member of the ferric uptake regulator family?

The family is named for its founding member, known as the ferric uptake regulator or ferric uptake regulatory protein ( Fur ). Fur proteins are responsible for controlling the intracellular concentration of iron in many bacteria.

Is there a ferric uptake regulator in E coli?

A mutation in Ferric Uptake Regulator (Fur) encoded by the fur gene was identified in E. coli mutants that exhibited constitutive expression of iron uptake genes ( Hantke, 1981, 1984; Bagg and Neilands, 1985 ).

What's the maximum dose of Ferrlecit you can take?

The maximum dosage should not exceed 125 mg per dose. Ferrlecit is available as a single-dose vial, containing 62.5 mg of elemental iron in 5 mL volume. Known hypersensitivity to sodium ferric gluconate or any of its components.

How are ferrites can prevent and eliminate RF?

Extensive laboratory work has shown that ferrite chokes make very effective RFI filters if properly applied. This Tech Topic stud- ies the use of ferrites to eliminate RF interference to audio systems. Ferrites are ceramics consisting of various metal oxides formulated to have very high per- meability.
