Lytic and Non-Lytic Permeabilization of Cardiolipin-Containing Lipid Bilayers Induced by Cytochrome c
The release of cytochrome c (cyt c) from mitochondria is an important early step during cellular apoptosis, however the precise mechanism by which the outer mitochondrial membrane becomes permeable to these proteins is as yet unclear. Inspired by our previous observation of cyt c crossing the membrane barrier of giant unilamellar vesicle model systems, we investigate the interaction of cyt c wi...
متن کاملCytochrome c causes pore formation in cardiolipin-containing membranes.
The release of cytochrome c from mitochondria is a key signaling mechanism in apoptosis. Although extramitochondrial proteins are thought to initiate this release, the exact mechanisms remain unclear. Cytochrome c (cyt c) binds to and penetrates lipid structures containing the inner mitochondrial membrane lipid cardiolipin (CL), leading to protein conformational changes and increased peroxidase...
متن کاملCytochrome C interaction with cardiolipin/phosphatidylcholine model membranes: effect of cardiolipin protonation.
Resonance energy transfer between anthrylvinyl-labeled phosphatidylcholine as a donor and heme moiety of cytochrome c (cyt c) as an acceptor has been employed to explore the protein binding to model membranes, composed of phosphatidylcholine and cardiolipin (CL). The existence of two types of protein-lipid complexes has been hypothesized where either deprotonated or partially protonated CL mole...
متن کاملCardiolipin synthesis for the assembly of bacterial and mitochondrial membranes.
In this article, the formation of prokaryotic and eukaryotic cardiolipin is reviewed in light of its biological function. I begin with a detailed account of the structure of cardiolipin, its stereochemistry, and the resulting physical properties, and I present structural analogs of cardiolipin that occur in some organisms. Then I continue to discuss i) the de novo formation of cardiolipin, ii) ...
متن کاملAn investigation into the use of cardiolipin antigens. II. Complement-fixing properties of cardiolipin Wassermann antigen.
Complement-Fixing Properties of Cardiolipin This reagent was examined using two ranges of 0-6 per cent. to 0 0045 per cent. One range was suspended in saline at a dilution of 1 in 50 and the other at 1 in 200. No fixation of complement was obtained when using syphilitic sera. Mixtures of cardiolipin and lecithin were next tested for their complement-fixing ability in the presence of a suitable ...
