abstract：:Crystallographic studies on flavodiiron proteins (FDPs) have revealed that the common sequence core ( approximately 400 residues) that defines this protein family comprises two structural domains. The N-terminal domain (of approximately 250 residues) displays a metallo-beta-lactamase-like-fold, being indeed structural...
