==Overview==
==Overview==
The X-ray crystallographic structures of two mutants (K206Q and H207E) of the N-lobe of human transferrin (hTF/2N) have been determined to high resolution (1.8 and 2.0 A, respectively). Both mutant proteins bind iron with greater affinity than native hTF/2N. The structures of the K206Q and H207E mutants show interactions (both H-bonding and electrostatic) that stabilize the interaction of Lys296 in the closed conformation, thereby stabilizing the iron bound forms.
