  • Title: Free radical fragmentation of cardiolipin by cytochrome c.
    Author: Yurkova I, Huster D, Arnhold J.
    Journal: Chem Phys Lipids; 2009 Mar; 158(1):16-21. PubMed ID: 18983994.
    Abstract:
    The effect of cytochrome c (cyt c) on degradation of cardiolipin in its polar part was investigated in cardiolipin/phosphatidylcholine (CL/PC) liposomes incubated with cyt c/H(2)O(2)/and (or) ascorbate by high-performance thin layer chromatography and MALDI-TOF mass spectrometry. It has been shown that phosphatidic acid (PA) and phosphatidylhydroxyacetone (PHA) were formed in the system under conditions where hydrogen peroxide favours a release of heme iron from cyt c. The formation of PA and PHA occurs via an OH-induced fragmentation taking place in the polar moiety of cardiolipin. Formation of fragmentation products correlated with the loss of CL in CL/PC liposomes incubated with cyt c/H(2)O(2)/ascorbate or with Cu(2+)/H(2)O(2)/ascorbate.
