초록

The Vibrio vulnificus vuuA gene, of which expression is repressed by a complex of iron and ferric uptake regulator (Fur), was characterized to localize the Fur-binding site in its upstream regulatory region. In silico analysis suggested the presence of two possible Fur-binding sites; one is a classical Fur-box and the other is a previously reported distinct Fur-binding site. Site-directed mutagenesis and DNase I protection assays revealed the binding site for the iron-Fur complex, which includes an extended inverted repeat containing a homologous sequence to the classical Fur-box.
