The capability for electrogenic inward transport of substrates that carry different net charge is a phenomenon observed in a variety of membrane-solute transporters but is not yet understood. We employed the two-electrode voltage clamp technique combined with intracellular pH recordings and the giant patch technique to assess the selectivity for bidirectional transport and the underlying stoichiometries in proton to substrate flux coupling for electrogenic transfer of selected anionic, cationic… CONTINUE READING
