Electrodes modified with lipid membranes to study quinone oxidoreductases.

Abstract:

:Quinone oxidoreductases are a class of membrane enzymes that catalyse the oxidation or reduction of membrane-bound quinols/quinones. The conversion of quinone/quinol by these enzymes is difficult to study because of the hydrophobic nature of the enzymes and their substrates. We describe some biochemical properties of quinones and quinone oxidoreductases and then look in more detail at two model membranes that can be used to study quinone oxidoreductases in a native-like membrane environment with their native lipophilic quinone substrates. The results obtained with these model membranes are compared with classical enzyme assays that use water-soluble quinone analogues.

  • Impact of post-translational modifications of proteins on the inflammatory process.

    abstract::PTM (post-translational modification) is the chemical modification of a protein after its translation. The well-studied PTM is phosphorylation, but, recently, PTMs have been re-focused by extensive studies on histone modifications and the discovery of the ubiquitin system. Histone acetylation is the well-established e...
