Bacterial Iron Transport (Ferric Binding Protein)

Objective:
To investigate the mechanism of ferric binding protein mediated transport of Fe across the periplasmic space of Gram negative pathogens. Our approach is to characterize the coordination chemistry of ferric binding protein, a bacterial transferrin, using spectroscopic, kinetic and thermodynamic techniques.
