  • Title: Cytochrome c specifically induces non-bilayer structures in cardiolipin-containing model membranes.
    Author: de Kruijff B, Cullis PR.
    Journal: Biochim Biophys Acta; 1980 Nov 18; 602(3):477-90. PubMed ID: 6254562.
    Abstract:
    (1) The effect of cytochrome c addition on the phospholipid structure of liposomes composed of cardiolipin, phosphatidylserine, phosphatidylglycerol, phosphatidylcholine or phosphatidylethanolamine in a pure form or in mixtures was investigated by 31P-NMR and freeze-fracture techniques. (2) Cytochrome c specifically induces the hexagonal Hii phase and possibly an inverted micellar structure of part of the phospholipids in cardiolipin-containing model membranes. (3) These results are compared with the effect of Ca2+ on cardiolipin and are discussed in relation to the structure and function of the inner mitochondrial membrane.
