  • Title: [The role of the state of protein-lipid interactions in stimulated membranes in the conformation of C40-carotenoids].
    Author: Maksimov GV, Musuralieva GT, Churin AA, Pashchenko VZ.
    Journal: Biofizika; 1989; 34(3):420-4. PubMed ID: 2788461.
    Abstract:
    It was shown by Raman spectroscopy that conformation of carotenoid in the frog nerve membranes at rest and at propagation of rhythmic excitation depends on the state of protein-lipid interaction modified by exposition of the nerve in solution with trypsin, alpha-chymotrypsin, urea, glutaraldehyde, SH-reagents, isopropanol and system "Fe-ascorbate". It is suggested that the level of the protein-lipid interactions in excitable membranes with the intramembrane potential determines C40-carotenoid conformation at the propagation of rhythmic excitation by he nerve.
