RESULTS AND DISCUSSIONS Screen for Fur-regulated Promoters and Sequence Analyses of DNA Regions Identified by FURTA Fur-regulated promoters and iron binding proteins carried on a plasmid can be identified by transference into E. coli H1717 ( Stojiljkovic et al. , 1994 ) , which carries fhuF < lacZ ; a Fur-regulated gene fusion sensitive to changes in repressor ( Fur-Fe ) þ2 concentration .

Members of the Fur protein family regulate iron and zinc transport in Escherichia coli and characteristics of the Fur-regulated fhuF protein .

Regardless of the explanation , these results appear at odds with previous studies , which established that cells exposed to Co contain less iron and reported up-regulation of Fur-controlled entB and fhuF also directly destabilize particularly labile Fe -- S clusters such as those present on Fe -- S scaffolds .
