1. Electron and Proton Transfer in Nitric Oxide Reductase : NO Binding, NO Reduction and no Pumping
Abstract : Nitric oxide reductase (NOR) from Paracoccus denitrificans catalyzes the two electronreduction of NO to N2O (2NO + 2H+ + 2e- → N2O + H2O) as part of the process ofdenitrification, the step-wise reduction of nitrate to dinitogen. The NOR-catalyzedreaction is central in the nitrogen cycle, since in this step the N=N double bond isformed. READ MORE

2. Active Transport of Ions across Biomembranes : A Kinetic Study of Cytochrome c Oxidase Reconstituted into Phospholipid Vesicles
Abstract : Ion transport across membranes is of uttermost importance for us. It is the foundation for signaling of various kinds e.g. in the nerve-system. READ MORE

3. Proton transfer across and along biological membranes
Abstract : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. READ MORE

4. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP
Abstract : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. READ MORE

5. Structure and Function of Cytochrome c Oxidase
Abstract : Aerobic organisms, ranging from bacteria to humans, obtain their energy through the process of respiration. Electrons from the breakdown of food are transported through the membrane-bound enzyme complexes of the respiratory chain, to the terminal acceptor molecule, oxygen. READ MORE
