Crystal structure of the Vibrio cholerae ferric uptake regulator (Fur) reveals insights into metal co‐ordination
Open accessAbstract
Summary: The ferric uptake regulator (Fur) is a metal‐dependent DNA‐binding protein that acts as both a repressor and an activator of numerous genes involved in maintaining iron homeostasis in bacteria. It has also been demonstrated in Vibrio cholerae that Fur plays an additional role in pathogenesis, opening up the potential of Fur as a drug target for cholera. Here we present the crystal structure of V. cholerae Fur that reveals a very different orientation of the DNA‐binding domains compared with that observed in Pseudomonas aeruginosa Fur. Each monomer of the dimeric Fur protein contains two metal binding sites occupied by zinc in the crystal structure. In the P. aeruginosa study these were designated as the regulatory site (Zn1) and structural site (Zn2). This V. cholerae Fur study, together with studies on Fur homologues and paralogues, suggests that in fact the Zn2 site is the regulatory iron binding site and the Zn1 site plays an auxiliary role. There is no evidence of metal binding to the cysteines that are conserved in many Fur homologues, including Escherichia coli Fur. An analysis of the metal binding properties shows that V. cholerae Fur can be activated by a range of divalent metals.

“Crystallographic studies of E. coli Fur (10) and its homologs from other bacteria (11, 12, 13, 14, 15) revealed that Fur proteins may exist as a homodimer or a tetramer, with each monomer containing three metal-binding sites: site 1 (coordinated by His-87, Asp-89, Glu-108, and His-125) is located within the dimerization domain; site 2 (coordinated by His-33, Glu-81, His-88, and His-90) connects”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
