  • 功能：
    Acts as a global negative controlling element, employing Fe(2+) as a cofactor to bind the operator of the repressed genes. Regulates the expression of several outer-membrane proteins including the iron transport operon.
  • 基因功能参考文献：
    1. The influence of oxygen availability on the levels of active Fur adds a previously undescribed layer of regulation in maintaining cellular iron homeostasis in E. coli. PMID: 29087312
    2. High iron supply inhibits the synthesis of the genotoxin colibactin by pathogenic Escherichia coli through a non-canonical Fur/RyhB-mediated pathway. PMID: 28637194
    3. Finally, Fur derepression and RecA activation in enterohemorrhagic Escherichia coli O157 were shown to participate in the nitric oxide-enhanced Stx1 and Stx2 production, respectively. PMID: 28294553
    4. The s report that O2 availability affects the gene expression programs of two Escherichia coli master regulators that function in iron homeostasis: the transcription factor Fur and the small RNA regulator RyhB. PMID: 26670385
    5. The key regulator of the response to serum-active and inactive-is the iron regulator Fur, which controls the expression of more than 80% of the serum-upregulated genes. PMID: 25118243
    6. Fur exhibits a comprehensive regulatory role affecting many fundamental cellular processes linked to iron metabolism in order to coordinate the overall response of E. coli to iron availability. PMID: 25222563
    7. s demonstrated that the EHEC lpf2 operon is regulated in response to temperature, pH, bile salts and iron, during the exponential phase of growth, and is controlled by Fur. PMID: 24966050
    8. In a murine model of urinary tract infection (UTI), deletion of fur alone did not attenuate virulence, whereas a DeltaryhB mutant and a Deltafur DeltaryhB double mutant showed significantly reduced bladder colonization. PMID: 25245805
    9. There is a transient change in the activity of the iron regulator Fur and of the oxidative stress regulator SoxS after Zn addition. PMID: 22016571
    10. results presented here show that ftnA iron induction is independent of RyhB and instead involves direct interaction of Fe(2+)-Fur with an 'extended' Fur binding site (containing five tandem Fur boxes) located upstream (-83) of the ftnA promoter. PMID: 20015147
    11. H2O2-inducible antioxidant defense system leading to an increase in catalase; hydroperoxidase HPI activity, is unaltered in Deltafur mutants PMID: 15878120
    12. Tyr 55 of Escherichia coli Fur, as well as the two thymines in positions 18 and 19 of the consensus Fur Box, are involved with binding. PMID: 16212958
    13. Affinity of Fur for different metals was determined & ranges over several orders of magnitude in the order: Zn(II)>> Co(II)> Fe(II)> Mn(II). Only Fe(II) binds with sufficient affinity to activate Fur significantly at physiological metal levels. PMID: 16216078
    14. an activation mechanism for E. coli Fur involves the folding/unfolding of the N-terminal helix PMID: 16690618
    15. Fur protein translation is coupled to that of an upstream open reading frame, translation of which is downregulated by the non-coding RNA RyhB. PMID: 17268550
    16. Fur function may be antagonized by intracellular H2O2 by oxidizing the Fur:Fe(2+) complex and inactivating repressor function. PMID: 17462026
    17. In this study, information theory was used to identify new Fur binding sites, 13 of which we confirmed experimentally. PMID: 17921503
    18. In the fur+ strain compared to those in the fur- strain, expression of chromosomal dihydroorotase activity and beta-galactosidase activity of pyrC-lacZ fusion plasmid was repressed to about 30% and 17%, respectively. PMID: 18176545
    19. The characteristic metabolism of rpoS mutants required the activity of Fur (ferric uptake regulator) in order to decrease the synthesis of the small RNA RyhB that might otherwise inhibit the synthesis of iron-rich proteins. PMID: 18556786
    20. Binding of both zinc and iron ions induced a similar change in Fur conformations, but shifted residues closer to DNA in a different manner. PMID: 19023664
    21. transcriptomic data identified the global transcription regulators ArcA, CRP, Fis, FNR, Fur, BaeR, CpxR, and IHF as targets and potential CO sensors PMID: 19091747
