Zinc transporters have crucial roles in cellular zinc homeostatic control. The 2.9-A resolution structure of the zinc transporter YiiP from Escherichia coli reveals a richly charged dimer interface stabilized by zinc binding. Site-directed fluorescence resonance energy transfer (FRET) measurements and mutation-activity analysis suggest that zinc binding triggers hinge movements of two electrically repulsive cytoplasmic domains pivoting around four salt bridges situated at the juncture of the cytoplasmic and transmembrane domains ...
