WebTwo different procedures were used to prepare pure samples of 'cytochrome b1' (column chromatography) and 'bacterioferritin' (immunoprecipitation) from Escherichia coli K-12 strain CA265. Both were crystallized, and X-ray-crystallographic data were compared with those from the bacterioferritin of E. coli strain W3300 used as a standard. We conclude … WebIron starvation did not substantially affect cellular levels of CsrA or its small RNA (sRNA) antagonists, CsrB and CsrC. csrA disruption led to increased resistance to the lethal …
WebFeb 5, 2002 · All these genes encode iron-containing proteins, some of which are involved in iron storage. Our data suggest that the iron-sensor protein Fur positively regulates intracellular iron use and storage indirectly, by repression of RyhB in the presence of iron. Materials and Methods Bacterial Strains. WebFtnA and Bfr encode the distantly related iron-storage proteins ferritin and bacterioferritin, respectively. The plasmids carrying these genes were introduced individually into the Δfur background. Overproduction of any of these iron-storage proteins suppressed resistance evolution (fig. 3C). Taken together, both extracellular iron uptake and ...
WebIron storage proteins, ferritin (Ftn) and bacterioferritin (Bfr), are dynamic regulators of iron levels in bacteria. Ftn and Bfr appear to be essential for the survival and virulence of pathogens in a host, suggesting that these molecules may be good targets for the development of new antibiotics.
