  • Title: [Energy levels and ion wave functions in gramicidin channels].
    Author: Dmitriev AV, Isaeva GA, Isaev PP, Baryshnikov VG, Lastochkin AV.
    Journal: Biofizika; 2002; 47(5):864-8. PubMed ID: 12397958.
    Abstract:
    A model study of the motion of Na+ ions in the cavity of membrane gramicidin channels was performed by the methods of quantum mechanics. An approximation of the distribution of the electrostatic potential along the channel axis, determined by charges on the atoms of the gramicidin A molecule, was obtained. The energy distribution and the wave functions for the stationary states of the ions were determined. The solutions of the Schrödinger equation for two conformers were compared.
