Cation Interactions and Membrane Potential Induce Conformational Changes in NaPi-IIb.

Biophysical journal - 6 Sept 2016

Patti Monica, Fenollar-Ferrer Cristina, Werner Andreas, Forrest Lucy R, Forster Ian C

Abstract excerpt

Voltage-dependence of Na(+)-coupled phosphate cotransporters of the SLC34 family arises from displacement of charges intrinsic to the protein and the binding/release of one Na(+) ion in response to changes in the transmembrane electric field. Candidate coordination residues for the cation at the Na1 site were previously predicted by structural modeling using the x-ray structure of dicarboxylate transporter VcINDY...
