Predicted changes in ΔG associated with Ae4 activity. ΔG values calculated for Ae4 transport activity assuming stoichiometries of Cl−:Na+:HCO3− as 1:1:2 (top row), 1:2:3 (middle row), and 2:1:3 (bottom row), respectively. The intracellular Cl− (left column), Na+ (middle column), and HCO3− (right column) were individually changed (from 0.5 to 150 mM) while the other concentrations were kept fixed at [Cl−]i = 50.1 mM, [Na+]i = 15.5 mM, or [HCO3−]i = 19 mM.
