Sequence of ionophore conformational changes induced by a simulated membrane/water interface.
We demonstrate how the progressive passage through an interface simulated by a linear increase in dielectric constant may mediate a reversible transconformation of Na+/X537A (lasalocid A) from a cyclic to an extended structure. During the passage through the interface, the complex adopts progressively a more extended conformation favorable to the Na+ complexation or decomplexation at the interface.
