Alignment of N. europaea Fur homolog coding sequences with E. coli and P. aeruginosa Fur proteins using ClustalW [31]. Identical residues are shaded black, with similar residues shaded grey. Metal binding site 1 residues are indicated with circles, and site 2 residues are indicated with triangles, as identified from the crystal structure of P. aeruginosa Fur. Residues indicated by straight line highlight a motif thought to be involved in DNA binding.
