Methods Decision tree analysis was carried out using clinical data collected from 1502 stroke patients with same subtypes diagnosed identically by two experts with more than 3 years of clinical experience. Among 9 tongue indicators, 6 major tongue indicators (red tongue, pale tongue, yellow fur, white fur, thick fur, teeth-marked tongue) were selected by decision tree analysis. Each PI has a sp...
Vibrio anguillarum Fur mutants, 775met9 and 775met11, were characterized. V. anguillarum 775met9 had a change of D to G at position 104 located in the carboxy terminus resulting in impaired Fur activity. Computer analysis predicts perturbation of an alpha-helix in the carboxy terminus which may interfere with Fur protein conformation. Strain 775met11 had a change in the start codon resulting in...
BACKGROUND Availability of the essential nutrient iron is thought to vary greatly in the gastric mucosa, and thus the human gastric pathogen Helicobacter pylori requires regulatory responses to these environmental changes. Bacterial iron-responsive regulation is often mediated by Ferric Uptake Regulator (Fur) homologs, and in this study we have determined the role of H. pylori Fur in regulation...
The iron-directed, coordinate regulation of genes depends on the fur (ferric uptake regulator) gene product, which acts as an iron-responsive, transcriptional repressor protein. To investigate the biological function of a fur homolog in the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1, a fur knockout strain (FUR1) was generated by suicide plasmid integration into this gene ...
We previously identified a novel regulator of the exotoxin A gene (toxA) in Pseudomonas aeruginosa, PtxR, that belongs to the LysR family of prokaryotic regulatory proteins. Preliminary data also suggest that PtxR affects the expression of siderophores in P. aeruginosa. Because toxA expression and siderophore production in this organism are coordinately regulated by the ferric uptake regulator ...
